CHAPTER 1 INTRODUCTION
1.1
Description
The GE family of Air Data Test Sets (ADTS) provide accurate air data to test two, three and fourchannel systems.
The manufacturer has designed this equipment to be safe when operated using the procedures
detailed in this user manual.
The required aircraft instrument test values can be entered in either aeronautical or pressure
units. The ADTS will then automatically generate the correct pressure aims for all required
channels.
The aircraft air data computer system receives these parameters and calculates altitude, airspeed
and angle of attack (if applicable).

Positioning the ADTS
CAUTION
TO OPERATE, PLACE THE ADTS ON A HORIZONTAL SURFACE WITH THE FRONT PANEL UPPERMOST ,
THIS ALLOWS THE WATER IN THE WATER FILTER TO VENT . WATER CAN CONTAMINATE THE ADTS
MANIFOLD AND AFFECT ADTS PERFORMANCE.
Note: In control mode, the water drain, located near the cooling vent, produces a flow of air and some
water. The amount of water depends on the humidity and the operating time in control mode.
It is important that the position of the ADTS in relation to the aircraft altitude sensors is known. An
altitude correction must be made to allow for the difference in height between the ADTS reference
level and the reference level of the aircraft's altitude sensors (refer to the Aircraft Maintenance
Manual for this information).
Enter the altitude correction value, see section 3.6, Settings, ADTS settings menu.

Manual Venting of the Aircraft Pitot and Static Systems
ADTS status on power failure
On removal of power, the main output valve linking external ports Pt and Ps to the internal pressure
controllers will automatically close. The aircraft pitot and static systems remain safe but with the last
applied pressures now isolated and maintained in the hoses.
ADTS status on restoration of power
When power is restored to the ADTS the normal self test routine for the ADTS will be performed and at
the end of this the ADTS will exactly equalize the internal manifold pressures to match those of the
external aircraft hoses and then the output valves will be reopened. This process will at all times
protect the aircraft pitot and static systems from adverse pressure transients, differentials or
excessive rates.
When the output valves are fully opened, the normal parameter measurement screens become
available from the Dashboard and full control is again available. The testing may then either continue
from the same point (when the power failure occurred) or the aircraft pitot and static systems may be
safely controlled back to ground pressures.
Actions if power cannot be quickly restored
Two courses of action are possible at this point:
1. Leave the ADTS connected to the aircraft pitot and static systems with pipes safely isolated but
maintaining trapped pressures until such time as power can be restored.
2. Use the manual let-down valves on the ADTS front panel to safely bleed the trapped hose pressures
back to ambient ground. This must be carried out in a way that ensures the Pt to Ps differential
pressure remains at zero while the whole connected system is brought to ground pressure.
Open the valves slowly while monitoring the cockpit gauges for any excessive rate of change.
The order the manual let-down valves are opened is:

CHAPTER 4 CALIBRATION
4.1
Introduction
For the system to remain accurate, a calibration check should be carried out at regular intervals.
The recommended calibration period is 12 months. If the accuracy of the system is not within the
specification, carry out a calibration adjustment.
4.2
PIN protection
The ADTS contains some PIN protected menus, the Operating limits and the “Calibration” menu.
The factory set PIN codes are sent to the supervisor in a separate envelope.
Important note
Change these codes to prevent unauthorised access. Unauthorised access to these menus can
make this system inaccurate and could, in control mode, cause excessive rates of pressure
change.
4.3
Calibration process
This chapter describes the Ps and Pt sensor calibration. The “Tools”, “Calibration” “Sensor” menu
contains the PIN (default, 4321) protected calibration adjustment function “Calibration check”.
Note: Calibration checks must be performed from within the calibration check menu because the main
Ps/Pt measure display screen Pt readings may include “Auto Zero” offset.

procedure detailed below.
6. Repeat this procedure for the other channel.
Calibration adjustment
The procedure applies known pressures to the ADTS and then entering the exact applied pressure
using the ADTS Touch. After all calibration points have been entered, the ADTS automatically
calculates the necessary offset (zero) and slope (span) corrections.
The date of calibration adjustment is logged and stored during this procedure. It is important that the
ADTS Touch clock date is checked before starting a calibration adjustment or an incorrect date may
be recorded. Instructions for checking and setting the time and date can be found in section 3.6.
1. Select Ps/Pt. The Ps/Pt sensor correction screen opens.
2. Follow the on-screen instructions.
3. Repeat this procedure for the other channel.
4.5
Completion of sensor calibration
After completion of all calibration adjustment procedures, carry out the following:
• Make sure the calibration standard and the ADTS are at atmospheric pressure. Disconnect the
calibration standard from the ADTS.
• If there is no further calibration or testing required, exit menus, select standby or switch off the ADTS.
