PITOT STATIC
[EN] English 41 K0553 Revision D
Figure 3-6: Measure mode screen - Multi Channel
You can switch the system between aero units and pressure units using the toggle control (4).
Control mode
When CONTROL mode is selected at icon (1), the ADTS pumps and pressure control functions are
activated but will not cause any change in the current pressures unless requested by the oper-
ator.
The CONTROL mode screen also displays real time Pitot Static parameter measurements based
on the current pressures and rates of change of pressures present at the Ps and Pt ports. It also
has a 'Aim' field for each parameter to allow you to enter new target values for the controller of
the ADTS or any connected aircraft systems.
This screen may be configured at icon (2) to accept and present data in either aeronautical or
pressure units.
The Pt channel display may be configured at icon (3) to present either CAS or Mach (when in Aero
units) and either Qc or Pt (when in Pressure units).
A progress bar (4) indicates rate and percentage completion towards the requested new target
aim.
The effort meter (5) can swing left or right according to whether control of the requested pres-
sure for that channel is requiring predominantly vacuum (left) or pressure (right), e.g, an exces-
sive left swing when at an altitude set-point might give early indication of a leak to atmosphere
(continuous drain on vacuum pump resource).
