3.7.4 Mach Test and Constant Mach
Example
To go to 0.45 Mach, proceed as follows:
•
Press
LEAK MEASURE/CONTROL
to enter Control Mode.
•
Press
SPEED/Qc
then
RATE
to display rate of change of airspeed.
•
The preset rate of speed is 300 kts/min.
•
Press
MACH/Pt
.
•
Enter an aim of 0.45.
•
Wait for the Mach aim to be achieved.
•
The system keeps the Mach aim constant by controlling/changing Pt (pitot) leaving Ps
(static) at a constant value.
On completion of testing, select
GROUND
and wait for the `Safe at Ground' message to be displayed,
see 3.7.8., refit the pitot and static blanking caps.
Notes
1
If the altitude Ps (static) changes, the system automatically adjusts Pt (pitot) to keep the Mach
value constant.
2
Use the nudge facility for small changes to the Mach aim value.
