1 INTRODUCTION AND DESCRIPTION
This three channel air data test system provides accurate air data to test a three port, pitot-static
Smart Probe ™and other three-channel systems. To control the system, a touch screen on the
front panel enables the user, using a stylus (supplied), to send commands to each control channel
and to control test pressures either manually or from a stored test sequence. An advanced hand
terminal connected to the front panel can perform the same functions as the touch screen.
User-written test sequences, produced on a spreadsheet program can be uploaded from a pc to
the ADTS 2XX. Once stored in the system, the test sequence uses tables of pressure data to
simultaneously generate pressure aims for all three channels.
Smart Probe ™
The probe uses three pressure measurement channels identified as Ps1, Ps2 and Pt. The aircraft
air data computer system receives these three parameters and calculates altitude, airspeed and
angle of attack.
where:
Ps1 = static pressure
Pt = pitot pressure
Ps2 = static pressure
Ps1 = altitude
Ps1 - Pt = Qc (airspeed)
Ps1 - Ps2 = differential pressure, calculated with Qc, to produce angle of attack.

WARNING: DO NOT DISCONNECT THE ADVANCED HAND TERMINAL WHEN ENERGIZED IN THE
HAZARDOUS AREA. THIS CAN CAUSE AN EXPLOSION.
zTo operate safely, the ADTS 2XX must be placed outside the user defined zone 2 hazardous area.
Only the ATEX certified hand terminal may be used inside the defined zone 2 hazardous area (refer
to section 5 for a definition).
CAUTION:
TOOPERATE, PLACE THE UNIT ON AHORIZONTAL SURFACE WITH
THE FRONT PANEL UPPERMOST (A) OR WITH THE PNEUMATIC
CONNECTOR PS1 UPPERMOST (B) THIS ALLOWS THE WATER IN THE
WATER FILTER TO VENT. WATER COULD CONTAMINATE THE
CONTROLLER MANIFOLD AND AFFECT CONTROLLER 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 2XX 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 in the SET-UP menu detailed in section 3.
WARNING: OBSERVE THE APPROPRIATE SAFETY INSTRUCTIONS AND TESTING PROCEDURES DETAILED
IN THE AIRCRAFT MAINTENANCE MANUALS AND COMPONENT MAINTENANCE MANUALS.
