PERATION USING THE
ADTS542F
[EN] English 83 K0553 Revision D
The direct connections to the aircraft Pitot and Static ports should be made using the adaptor
set approved in the AMM, or using equivalents supplied by a specialist port adaptor manufac-
turer.
We do not recommend the use of improvised connections since this can lead to excessive
leakage and potential damage to the aircraft avionics systems.
When all the required pipework has been connected, the ADTS should be turned on as soon as
possible to allow a few minutes for it to reach a stable operating temperature. This is a safe
action for the aircraft regardless of whether the ADTS Touch is connected or not at this time. No
changes in pressure will be applied to the aircraft until actively requested. Make the ADTS Touch
data connection to the ADTS, either by Bluetooth® data connection or cable (see section Blue-
tooth®).
Altimeter and Airspeed Indicator Testing
Limits Protection Checks
The ADTS will automatically power up with the HELICOPTER limits in force. This table enforces the
most restricted control range on the ADTS output pressures, so this default configuration is the
safest of the predefine limit sets if working on small, low speed aircraft.
Consult the AMM to check the approved maximum test ranges for Altitude, Rate of Climb,
Airspeed and Mach for your aircraft
It is important to have the ADTS limits set correctly configured for the following reasons:
a) Prevents operators mistakenly entering test aims which exceed the aircraft maximums.
b) Provides early real time warnings that ranges and rates are being exceeded (due to Pitot Static
system leak etc.,).
c) Will prevent inadvertent creation of excessive Mach conditions due to selection of inappro-
priate altitude and airspeed combinations.
d) Will ensure that the ADTS can successfully reach any extended range test points as required.
