Pneumatic Pressure Connections

When not in use, blanking caps must be fitted to Ps/Pt ports.
Note: When carrying out a leak test, a leak of the blanking cap affects the performance of the ADTS.
The ADTS uses the following AN pneumatic connectors:
• AN-3, 37° flare (option)
• AN-4, 37° flare
• AN-6, 37° flare (option).

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.
