IAS Indicated Airspeed: is the speed shown on the on-board airspeed indicator. TAS True Airspeed: is calibrated airspeed corrected for altitude and temperature. VFE Maximum Flap Extended Speed: is the highest speed permissible with wing flaps in a prescribed extended position. VNO Maximum Structural Cruising Speed: is the speed that should not be exceeded except in smooth air, then only with caution. VNE Never Exceed Speed: is the speed limit that may not be exceeded at any time. VS Stalling Speed. VS0 Stalling Speed or the minimum steady flight speed at which the airplane is controllable in the landing configuration at the most forward center of gravity. VX Best Angle-of-Climb Speed is the speed which results in the greatest gain of altitude in a given horizontal distance. VY Best Rate-of-Climb Speed is the speed which results in the greatest gain in altitude in a given time. Vr Rotation speed: is the speed at which the aircraft rotates about the pitch axis during takeoff Vobs Obstacle speed: is the speed at which the aircraft flies over a 15m obstacle during takeoff or landing October ‘ 98 1-11 COSTRUZIONI AERONAUTICHE TECNAM S.r.l. F LIGHT MANUAL P92 Echo P92 Echo/100 GENERAL Meteorological Terminology OAT Outside Air Temperature is the free air static temperature expressed in degrees Celsius (°C). TS Standard Temperature is 15°C at sea level pressure altitude and decreased by 2°C for each 1000 ft of altitude. HP Pressure Altitude is the altitude read from an altimeter when the barometric subscale has been set to 1013 mb. Engine Power Terminology RPM Revolutions Per Minute: is the number of revolutions per minute of the propeller, multiplied by 2.273 (912UL) or 2.4286 (912S) yields engine RPM. Airplane Performance And Flight Planning Terminology Crosswind Velocity is the velocity of the crosswind component for which adequate control of the airplane during takeoff and landing was actually demonstrated. Usable fuel is the fuel available for flight planning. Unusable fuel is the quantity of fuel that cannot be safely used in flight. G is the acceleration of gravity. TOR is the takeoff distance measured from actual start to wheel liftoff point TOD is total takeoff distance measured from start to 15m obstacle clearing GR is the distance measured during landing from actual touchdown to stop point LD is the distance measured during landing, from 15m obstacle clearing to actual stop. S/R is specific range, that is, the distance (in nautical miles) which can be expected at a specific power setting and/or flight configuration per kilo of fuel consumed October ‘ 98 1-12 COSTRUZIONI AERONAUTICHE TECNAM S.r.l. F LIGHT MANUAL P92 Echo P92 Echo/100 GENERAL Weight And Balance Terminology Datum is an imaginary vertical plane from which all horizontal distances are measured for balance purposes. Arm is the horizontal distance from the reference datum to the center of gravity (C. G.) of an item. Moment is the product of the weight of an item multiplied by its arm. C. G. Center of Gravity is the point at which the airplane, or equipment, would balance if suspended. Its distance from the reference datum is found by dividing the total moment by the total weight of the airplane. Standard Empty Weight is the weight of a standard airplane, including unusable fuel, full operating fuels and full engine oil. Basic Empty Weight is the standard empty weight plus the weight of optional equipment. Useful Load is the difference between takeoff weight and the basic empty weight. Maximum Weight is the maximum weight of the aircraft. Maximum Takeoff Weight is the maximum weight approved for the start of the takeoff run. Maximum Landing Weight is the maximum weight approved for the landing touch down. Tare is the weight of chocks, blocks, stands, etc. used when weighing an airplane, and is included in the scale readings. Tare is deducted from the scale reading to obtain the actual (net) airplane weight. October ‘ 98 1-13 COSTRUZIONI AERONAUTICHE TECNAM S.r.l.

Airframe Wing The wing is made up of a central light alloy torque box; a composite leading edge is attached to the front spar and geometrically similar flap and aileron are hinged to rear. Flaps and ailerons are both made up of an aluminum spar connected to formed sheet metal leading edge and ribs and are covered by a thermoretractible synthetic material. Fuselage The front part of the fuselage is made up of a truss structure with special steel tubing and, beginning at the cabin's rear section, by an aluminum alloy semimonococque structure. The engine housing is isolated from the cabin by a stainless steel firewall; the steel stringers engine mount is attached to the cabin's truss structure in four points. Empennage The vertical tail is entirely metal: the vertical stabilizer is made up of a twin spar with load carrying skin while the rudder consists of an aluminum torque stringer connected to light alloy ribs and skin. The horizontal tail is an all-moving type (stabilator); its structure consists of an aluminum tubular spar connected to ribs and leading edge; the entire structure is covered with thermoretractible synthetic material. Flight Controls Aircraft flight controls consist of aileron, rudder and stabilator control surfaces. The control surfaces are manually operated using a control stick for ailerons and stabilator and rudder pedals for the rudder; longitudinal control acts through a system of push-rods and is equipped with a trim tab. Aileron control is of mixed type with push-rods and cables; the cable control circuit is confined within the cabin and is connected to a pair of push-rods positioned in the wings that control ailerons differentially. Aileron trimming is carried out on ground through a small tab positioned on left aileron. October ‘98 7-49 COSTRUZIONI AERONAUTICHE TECNAM S.r.l.

F LIGHT MANUAL P92 Echo P92 Echo/100 GROUND HANDLING AND SERVICE Introduction This section contains factory-recommended procedures for proper ground handling and routine care and servicing. It also identifies certain inspection and maintenance requirements which must be followed if the aircraft is to retain its new-plane performance and dependability. It is wise to follow a planned schedule of lubrication and preventive maintenance based on climatic and flying conditions encountered locally. Airplane Inspection Periods Inspection intervals occur at 50, 100 hours and in accordance with special inspection schedules which are added to regularly scheduled inspections. Correct maintenance procedures are described in the aircraft’s Service Manual or in the engine’s Service Manual. Ground Handling Towing The aircraft is most easily and safely maneuvered by hand by pushing on wing struts near attachments or by pulling it by its propeller near the axle. A tow bar can be fixed onto nose gear fork. Aircraft may be steered by turning rudder or, for steep turns, by pushing lightly on tailcone to lift nose wheel. Parking And Tie-Down When parking airplane outdoors, head it into the wind and set the parking brake. If chocks or wedges are available it is preferable to use the latter. In severe weather and high wind conditions it is wise to tie the airplane down. Tie-down ropes shall be fastened to the wing strut attachments and anchoring shall be provided by ramp tie-downs. Nose gear fork can be used for front tie-down location. Flight controls shall be secured to avoid possible weathervaning to end travel damage of moving surfaces. For this purpose, seatbelts may be used to latch control stick to prevent its movement. Ottobre ‘98 8-55 COSTRUZIONI AERONAUTICHE TECNAM S.r.l. F LIGHT MANUAL P92 Echo P92 Echo/100 GROUND HANDLING AND SERVICE Jacking Given the light empty weight, lifting one of the main wheels can easily be accomplished even without the use of hydraulic jacks. It is in fact sufficient that while one person lifts one half-wing by acting on the spar immediately before the wingtip, another person places a suitable stand below the steel spring attachment. Leveling Aircraft leveling may become necessary to check wing incidence, dihedral or the exact location of CG. Leveling is obtained when the lower cabin edge and the main gear support beam are horizontal. Road Transport It is recommended to secure tightly all aircraft components onto the cart to avoid damage during transport. Minimum cart size are 7x2.5 meters. It is suggested to place wings under the aircraft’s bottom, secured by specific clamps. Secondary components such as stabilators and struts shall be protected from accidental hits using plastic or other material. For correct rigging and derigging procedure, refer to Service Manual. Cleaning and Care To clean painted surfaces, use a mild detergent such as shampoo normally used for car finish; use a soft cloth for drying The plastic windshield and windows should never be dusted when dry; use lukewarm soapy water and dry using chamois only. It is possible to use special glass detergents but, in any case, never use products such as gasoline, alcohol, acetone or other solvents. To clean cabin interior, seats, upholstery and carpet, it is generally recommended to use foam-type detergents. Ottobre ‘98 8-56
