By using the ADTS Touch controls it is possible to present the Ps and Pt channel data for each of the 6
test condition rows in all of the formats shown in the table. By using the settings menu to change
either the chosen pressure or aeronautical unit it is very simple to convert the displayed aims and
measurement values to the desired format. Such changes can be done without turning off control, so
the terminal can effectively also be used as a pressure converter/calculator when designing your
aircraft test procedures.
The aircraft status screen can be used to give you a very quick overview of whether the aircraft is
climbing, descending or at stable altitude. If you make a mistake with your data entry, use the orange
green "hand" symbol to stop ramping and HOLD stable the current pressure, while you consider and
correct the intended test point aim. Pressing the now orange "hand" again will release the hold when
you are ready. The "Hand" returns to green as ramping to the corrected aim begins again. If the ADTS
Touch loses radio link or the cable accidentally becomes severed, the ADTS will automatically enter
the HOLD state after 10 seconds. If communications has not been re-established after 10 minutes,
then the ADTS will automatically begin a descent to ground pressures.
End of testing
When testing is complete, use the Aircraft status screen to initiate a descent to ambient ground pres-
sure at a safe rate. The rate may be increased or decreased if required from within this screen. To see
full parameter details, simply clear the status screen view. It can be recalled at any time. If working
with the ADTS.
When the ADTS displays the status as AT GROUND, it is then safe to disconnect the aircraft Ps and Pt
connections. The ADTS base unit will also show steady green on the rightmost aircraft status LED
when in this state.
