CESSNA 172 TRAINING MANUAL
Introduction
This training manual provides a technical and operational description for most
models of the Cessna 172 series aeroplane, from the C172 and C172A to the
C172SP, and includes systems descriptions for the C172RG.
The information is intended for ground reference and as an instructional aid to
assist with practical training for type transition or ab-initio training, provided by an
approved training organisation.
The book is laid out according to a typical training syllabus progression for ease of
use.
This material does not supersede, nor is it meant to substitute any of the
manufacturer’s operation manuals. The material presented has been prepared from
the information provided in the pilots operating handbook for the model series,
Cessna maintenance manuals and from operational experience.
History
The Cessna aircraft company has a long and rich history. Founder Clyde Cessna
built his first aeroplane in 1911, and taught himself to fly it! He went on to build a
number of innovative aeroplanes, including several race and award winning designs.
In 1934, Clyde's nephew, Dwane Wallace, fresh out of college, took over as head of
the company. During the depression years Dwane acted as everything from floor
sweeper to CEO, even personally flying company planes in air races (several of
which he won!).
Under Wallace's leadership, the Cessna Aircraft Company eventually became the
most successful general aviation company of all time.
Cessna first began production of two-seat light planes in 1946 with the model 120
which had an all aluminium fuselage and fabric covered wings. This was followed by
a nearly identical model the 140, with aluminium clad wings. More than 7,000
model 120-140's were sold over four years when Cessna stopped production in
order to focus on four-seat aircraft.
Development of the C172
The Cessna 172 is probably the most popular flight training aircraft in the world.
The aircraft made her first flight in November 1955, the first production models
were delivered in 1957, and became an overnight sales success and over 1400
aircraft were built in its first full year of production. It is still in production in 2005,
more than 35 000 have been build.
The Cessna 172 started as a relatively simple tricycle undercarriage development of
the taildragger Cessna 170B. The airframe was basically a 170B, including the
“fastback” fuselage and effective 40º Fowler flaps. The gross weight was identical

CESSNA 172 TRAINING MANUAL
although the useful load went down 45 pounds. Later versions incorporated revised
landing gear, a lowered rear deck, and an aft window. Cessna advertised this added
rear visibility as “Omnivision”. The final structural development, in the mid-1960s,
was the sweptback tail still used today. The airframe has remained almost
unchanged since then, with updates mainly affecting avionics and engine fittings,
including the most recent the Garmin 1000 glass cockpit option. Production ended
in the mid-1980s, but was resumed in 1996 and continues at the time of writing.
The Cessna 172 evolved slowly over the years. The basic Cessna 172 remained in
production until replaced by the 172A of early 1960. The latest model of Cessna
172 introduced a new swept back tail and rudder, a shorter undercarriage and
changes of equipment. In 1961 the name "Sky Hawk" was introduced. The Cessna
172H was the last Continental powered 172. Electric flaps were introduced in 1964
with the 172E, and the 150hp Lycoming 0-320-E2D replaced the 145 hp Continental
0-300D in 1968.
In 1966 Cessna began assembly of US airframes at Reims Aviation in France. The
Cessna F172 was built by Reims Cessna through to 1971. Cessna also produced a
retractable version and most models are available as a seaplane version with
floats.
The Cessna 172 is part of a large family of high-wing, tricycle undercarriage, single
engine Cessna planes, ranging from the two-seater 150 and 152 to more advance
182 Skylane, the six-seat 206 and the turboprop Cessna 208 Caravan.

measurements of arm are taken. The datum is
established by the manufacturer.
Moment The product of the weight of an item multiplied by its
arm and expressed in inch-pounds. The total moment
is the weight of the aeroplane multiplied by distance
between the datum and the CG.

CESSNA 172 TRAINING MANUAL
Note: The correct technical is 'mass' instead of 'weight' in all of these terms, however in everyday
language and in many aircraft operating manuals the term weight remains in common use. Used in
this context there is no difference in meaning and the terms may be interchanged.

Pilot's Operating Handbook Information
The approved manufacturer's operating handbook, which may be commonly
referred to as a Pilot's Operating Handbook (POH), an Aircraft Flight Manual (AFM),
or an Owners Manual, is issued for the specific model and serial number, and
includes all applicable supplements and modifications. It is legally required to be on
board the aircraft during flight, and is the master document for all flight
information.
In 1975, the US General Aviation Manufacturer's Association introduced the 'GAMA
Specification No. 1' format for the 'Pilot's Operating Handbook' (POH). This format
was later adopted by ICAO in their Guidance Document 9516 in 1991, and is now
required for all newly certified aircraft by ICAO member states. Most light aircraft
listed as built in 1976 or later, have provided Pilot's Operating Handbooks (POHs) in
this format.
by D. Bruckert & O. Roud © 2006 Page 11
CESSNA 172 TRAINING MANUAL
GAMMA standardised the term 'Pilot's Operating Handbook' as the preferred term
for a manufacturer's handbook on light aircraft, however some manufacturers still
use different terms (see further explanation above under definitions).
This format aimed to enhance safety by not only standardising layouts but also by
creating an ergonomic format for use in flight. For this reason the emergency and
normal operating sections are found at the front of the manual, while reference and
ground planning sections are at the rear.
It is recommended that pilots become familiar with the order and contents of each
section, as summarised in the table below.
Section 1 General Definitions and abbreviations
Section 2 Limitations Specific operating limits, placards and specifications
Section 3 Emergencies Complete descriptions of action in the event of any
emergency or non-normal situation
Section 4 Normal

Section 5 Performance Performance graphs, typically for stall speeds, airspeed
calibration, cross wind calculation, takeoff, climb,
cruise, and landing
Section 6 Weight and

or tables
Section 7 Systems

Technical descriptions of aircraft systems, airframe,
controls, fuel, engine, instruments, avionics and lights
etc.
Section 8 Servicing

Maintenance requirements, inspections, stowing, oil
requirements etc.
Section 9 Supplements Supplement sections follow the format above for
additional equipment or modification.
Section 10 Safety
Information
General safety information and helpful operational
recommendations which the manufacturer feels are
pertinent to the operation of the aircraft
For use in ground training, or reference prior to flight, this text should be read in
conjunction with the POH from on board the aircraft you are going to be flying.
Even if you have a copy of a POH for the same model C182, the aircraft you are
flying may have supplements for modifications and optional equipment which affect
the operational performance.

AIRCRAFT TECHNICAL INFORMATION
The Cessna 172 aeroplane is an all-metal, single engine, four-seat, high-wing
monoplane aircraft, equipped with tricycle landing gear and designed for general
utility purposes.

CESSNA 172 TRAINING MANUAL
Models and Differences
The Cessna 172 had a number of type variants during its production history.
Additionally there are a number of modifications provided for the airframe,
instruments/avionics equipment and electrics.
Speeds often vary between models by one or two knots, sometimes more for
significant type variants. For simplification the speeds have been provided for the
C172 Skyhawk, which was produced in the largest numbers. All speeds have been
converted to knots and rounded up to the nearest 5kts. Generally multiple provision
of figures can lead to confusion for memory items and this application is safer for
practical use during conversion training.
Whenever maximum performance is required, as speeds also vary with
weight, and density altitude the Aircraft Operating Handbook must be
consulted for the correct figure.
During practical training reference should be made to the flight manual of the
aeroplane you will be flying to ensure that the limitations applicable for that
aeroplane are adhered to. Likewise when flying different models it should always be
remembered that MAUW, flap limitations, engine limitations and speeds may vary
from model to model.
Before flying different models, the Aircraft Operating Handbook should
be consulted to verify differences.
Main Differences in year of manufacturing
The following modification of Cessna 172 were made during years of production of
the aircraft:
The 1957 model has a 145hp Continental engine;
Model's after 1960 have a swept tail;
In 1963 a rear window appeared as well as a single piece windshield and longer
elevator;
1964 model were equipped with electric flaps instead of the “Johnson Bar”;
1968 models switched to Lycoming 150hp engines.
In 1971 the spring steel main landing gear was changed to tubular steel.
In 1981 Cessna switched to a 160-hp engine and gross weight of 2400lbs but
reduced flap travel of 30 degrees.
1996 and later models feature the Lycoming IO-360-L2A four cylinder, fuel
injected engine, an annunciator panel or optional Garmin G1000 EFIS avionics
suit.
A more comprehensive summary combined with serial numbers and model numbers
is contained in the table on the following pages.

CESSNA 172 TRAINING MANUAL
Naming Terminology
The C172 series manufactured by Cessna in Wichita, like most Cessna models,
started with the C172 followed by the C172A and continued sequentially up until
the C172 R and S, with the exception of the models J and O which never completed
certification. Each new model release superseding the previous, with the exception
of model variants (such as the 172RG and R172K).
Model Variants
Some models carried an alternate prefix or suffix to designate a specific difference,
or model variant as detailed below.
Reims 172
The F172 for models D through M, was made by Reims in France, and according to
Cessna there are no significant differences apart from the engines on models prior
to 1971 (F172K and earlier), however there are some differences in manufacturing
processes.
Cessna 175 Certified Aircraft
Although marketed as a C172, the P172D, F172/FR172 and C172RG were all
designated under the C175 type data certification sheet by the FAA.
The P172D, where the 'P' indicated the geared engine referred to as “Powermatic”
by Cessna. The different type designator also reflected a larger distinction, the
aircraft is nearly identical to the C175C and treated as such for certification, it has
little in common with the C172D except the year of manufacture (1963).
The C172 RG – where the 'RG' designated a retractable Cessna as with other
models of Cessna. Produced between 1981 and 1985, the RG option was not
reintroduced when production commenced in 1996.
The prefix 'R' was originally given to the 210hp military version C172, made
specifically for the US Air Force, and should not be confused with the Reims ('F')
models or the retractable ('RG') models. The original military R172 was produced
for models R172E through to R172H, between 1964 and 1973, called by the USAF a
T41-B, C or D, depending on options (the C172H, originally made for the USAF was
called the T41-A). Most models retired into USAF aeroclubs, a few are in civilian
use, and some still remain in US and other air force operations. These models led to
the development of a civilian version, the R172K given the name Hawk XP and the
FR172K, Reims Hawk XP or Reims Rocket, with the same engine de-rated to 195hp,
produced between 1977 and 1981.

CESSNA 172 TRAINING MANUAL
Airframe
The airframe is a conventional semi-monocoque type consisting of formed sheet
metal bulkheads, stringers and stressed skin.
Semi-monocoque construction is a light framework covered by skin that carries
much of the stress. It is a combination of the best features of a strut-type
structure, in which the internal framework carries almost all of the stress, and the
pure monocoque where all stress is carried by the skin.
The fuselage forms the main body of the aircraft to which the wings, tail section and
undercarriage are attached. The main structural features are:
front and rear carry through spars for wing attachment;
a bulkhead and forgings for landing gear attachment at the base of the
rear door posts;
a bulkhead and attaching plates for strut mounting;
four stringers for engine mounting attached to the forward door posts.
The construction of the wing and empennage sections consists of:
a front (vertical stabilizer) or front and rear spar (wings/horizontal
stabilizer);
formed sheet metal ribs;
doublers and stringers;
wrap around and formed sheet metal/aluminium skin panels;
control surfaces, flap and trim assembly and associated linkages.
by D. Bruckert & O. Roud © 2006 Page 23
CESSNA 172 TRAINING MANUAL
The front spars are equipped with wing-to-fuselage and wing-to-strut attach
fittings. The aft spars are equipped with wing-to-fuselage attach fitting, and are
partial-span spars. The wings contain the integral ie. non bladder type fuel tanks.
The empennage or tail assembly consists of the vertical stabilizer and rudder,
horizontal stabilizer and elevator.
Seats and Seat Adjustment
The seating arrangement consists of two separate adjustable seats for the pilot and
front passenger, a split-back fixed seat in the rear, and a child's seat (if installed)
aft of the rear seat.
The pilot and copilot seats are adjustable in
forward and aft position, and in most models
also for seat height and back inclination. When
adjusting the seats forward and aft care should
be taken to ensure the position is locked. Seat
locks are available and installed on many aircraft
following accidents involving slipping of seat
position during critical phases of flight. Seat
back and height should be adjusted to ensure
adequate visibility and control before start-up.
Doors
There are two entrance doors provided, one on the left and one on the fight, and a
baggage door at the rear left side of the aircraft.
The door latch on early models was not locked, however on later models rotation of
the inside handle 90 degrees provided a latched and locked position. To open the
doors from outside the aeroplane, utilize the recessed door handle by grasping the
forward edge of the handle and pulling outboard. If the door is locked from the
inside, it will be impossible to grasp the door handle.

CESSNA 172 TRAINING MANUAL
Engine and Propeller
The C172 is powered by a Continental or Lycoming horizontally opposed, air-cooled,
engine.
Early models of 172 (before 1967 models) are powered with Lycoming 0-300, six
cylinder engine, in later models was replaced with Lycoming 0-320, four cylinder
engine. The O-320 engine had three versions before being replaced by the O-360
engine. The O-360 had two variations before introduction of the fuel injected IO-
360 engine in the “restart” models (1996 and later)
The Cessna R172K, like it's predecessor, the R172E to H is powered by a six
cylinder Continental IO-360, de-rated with lower maximum rpm to 195hp.
The engine designator O means the engine is normally aspirated, and I indicates
fuel injection. The numbers (300, 320, 360) indicate the cubic capacity of the
engine. The horsepower developed varies with a number of factors including the
engine design, performance, and maximum rpm.
The engines develop the following power at sea level:
Continental O-300 145 horsepower at 2700 rpm, 6 cylinder (C172 to
C172H);

Fuel System
Fuel systems for the different models are shown in the schematic diagrams on the
following pages. Details of three different systems are shown for the standard
system, the C172RG and the fuel injected model. The C172 fuel system is gravity-
fed from fuel tanks located in the high wings.
In standard fuel system, fuel is supplied to the engine from two wing tanks (one in
each wing).
The following summarises the approximate* total and usable fuel on the various
models of C172:
C172 - 42 total, 37 usable US gallons (159/140 litres) standard fuel tanks;
C172A, B - 42 total, 39 usable US gallons (159/147 litres) standard fuel
tanks;
C172C to H - 39 total, 36 usable US gallons (147/136 litres) standard fuel
tanks;
C172I, K, L, M - 42 total, 38 usable US gallons (159/144 litres) standard fuel
tanks;
C172I, K, L, M - 52 total, 48 usable US gallons (201/186 litres) long range
fuel tanks;
C172N,P - 43 total, 40 usable US gallons (163/151 litres) standard fuel
tanks;
C172N,P - 42 total, 40 usable US gallons (159/151 litres) long range fuel
tanks;
C172P - 68 total, 62 usable US gallons (257/234 litres) wet wing fuel tanks;
C172Q - 54 total, 50 usable US gallons (204/189 litres) standard fuel tanks;
C172R,S - 56 total, 53 usable US gallons (212/200 litres) standard fuel
tanks;
P172 - 52 total, 41.5 usable US gallons (197/158 litres) standard fuel tanks;
FR172,R172K - 52 total, 49 usable US gallons (197/185 litres) standard fuel
tanks;
FR172,R172K - 68 total, 66 usable US gallons (257/250 litres) long range
tanks;
C172RG - 66 total, 62 usable US gallons (250/235 litres) standard fuel
tanks;
*these figures are approximate as variations exist between type certification
information, and maintenance manuals, and more importantly, it should be
remembered, individual manufacturing tolerances, tanks can be modified by STCs,
and density changes will give rise to slight variations in tank capacity. The usable
tank capacity should be placarded on the fuel selector of the model you are flying.
Check the POH for fuel system on particular aircraft you are going to fly for the
correct quantities and operational requirements.
The amount of fuel we can put into fuel tanks is limited by the volume of the tanks,
and therefore usable fuel is always provided in volume, such as gallons and litres.

CESSNA 172 TRAINING MANUAL
Electrical System
Electrical energy for the aircraft is supplied by a 14 or 28 volt, direct-current, single
wire, negative ground electrical system.
The system is either:
For models before 1967:
14 Volt system;
20, 35, or 50 amp generator;
12 volt battery with 25 or 33 amp-hours capacity.
For models after 1967, and before 1978:
14 Volt system;
52 or 60 amp alternator;
12 volt battery with a 25 or 33 amp-hours capacity.
For models 1979 and later:
28 volt system;
60 amp alternator;
24 volt battery with 17, 12.75 or optional 15.5 amp-hour capacity.
Additionally for models equipped with G1000 avionics:
24 volt standby battery (for operation of the G1000 essential bus only).
Battery
The 12 volt for models 1978 or earlier, or 24 volt lead-acid battery supplies power
for starting and furnishes a reserve source of power in the event of alternator
failure. The battery is mounted on the left forward side of the firewall (see picture
on the next page). Only the P172, C172RG, and R172 models. which are based on
the C175 airframe, have the battery mounted on the left hand side of the aft
fuselage behind the baggage compartment wall.
Battery capacity in amp-hours provides a measure of the amount of load the
battery is capable of supplying. This capacity provides a certain level of current for
a certain time. A 17 amp-hour battery is capable of steadily supplying a current of 1
amp for 17 hours and 2 amp for 8.5 hours and so on.
Standby Battery (G1000 Equipped Aircraft)
With G1000 equipped aircraft, a small standby battery is installed for the purpose of
maintaining electrical power to the G1000 essential bus. This powers the primary
flight display (PFD) and essential avionics and engine instruments in back up mode
only, in case of an electrical supply fault or failure of the main battery circuit.
The G1000 essential bus provides power to the PFD, AHRS, ADC, COM1, NAV1,
Engine and Airframe Unit, and standby instrument lights.

tracks, ensure rollers are free and in good
condition, and all fastenings secure.
Check for damage to surface and
security of all hinges, control
connections, and flutter weights.
Check condition, security and colour
of navigation light.
Check top and bottom wing surfaces
for any damage or accumulations. Ice
or excessive dirt must be removed
before flight.

Check visually for desired fuel level using
a suitable calibrated dipstick.
Check that fuel cap is secure again
after checking the fuel level.
Use sampler cup and drain a small
quantity of fuel from wing tank quick-
drain valve to check for water, sediment
and proper fuel grade.
Check the condition and security of
fairing (if fitted), strut and wheel.
Check the tyre for wear, cuts, bruises,
slippage and recommended tyre pressure.
Remember, any drop in temperature of
air inside a tyre causes a corresponding
drop in air pressure.
Check the security and condition of
hydraulic lines, disc brake assembly
and all fastenings.
Note, wherever possible roll aircraft forward, as any tyre damage or flat spots
will tend to come to rest on the point of contact with the ground where they
cannot be seen.

Nose
Check security of nuts and split pins,
state of tyre
Check freedom of operating linkage,
and security and state of shimmy
damper.
Check condition and security of air filter.
Air filter should be clear of any dust or
other foreign matter. Visually check
exhaust for signs of wear, if engine is
cool check exhaust is secure.
Check landing light and taxi lights for
condition and security (if cowl mounted).
Check oil level above minimum.
Before first flight of the day and after
each refuelling, take a fuel sample.
Check strainer drain valve, oil cap and
inspection cover are properly closed
once inspection complete.

Cruise at 10,000ft pressure altitude 2300 rpm 101 KTAS, 5.6 gph
*Cruise figures provided from the pilots operating handbook should be used with a
contingency factor, a block cruises speed and fuel flow that allows for contingency
and climb and descent are normally applied.
Ground Planning
Provided below is an example for completion of your ground planning. Blank forms
can be obtained from C172 POH and a flying school.
In this example, the airplane needs to carry two pilots, 20 pounds of baggage, and
sufficient fuel to fly 1.5 hours en route at 8000ft on a private flight under visual
flight rules.
Route Planning
The first step in any flight planning is to determine the route, this is normally
carried out on a Nav. Worksheet, then transferred to the Flight Log for use in flight.
An example of a Nav. Worksheet is shown below.
