3.9.6. Periodical rise and drop of boost pressure and speed (boost pressure control is
surging)
Orange caution lamp of TCU is not blinking.
Switch off
servo motor
for a moment
(max. 5 sec.). After a short regulating time operation should
stabilize.
ATTENTION:
If this action does not stabilize operation, switch off servo motor completely. If
needed, reduce engine speed until boost pressure and speed are within
the operating limits again.
Limited flying operation, as boost pressure control is no more possible.
Switching off the servo motor momentarily or permanently, has to be recorded by the pilot in the
logbook, stating the duration, exact time and duration of switching off.
3.9.7. Red boost lamp of TCU permanently illuminating
The maximum admissible boost pressure was exceeded.
Reduce speed and boost pressure manually to be within the operating limits.
Limited flying operation, as boost pressure control is no more or insufficiently possible.
ATTENTION:
The boost pressure will not be reduced automatically
In case of exceeding the max. admissible boost pressure, this has to be recorded by the pilot in the
logbook, stating the duration and exact time of exceeding of limits.
3.9.8. Red boost lamp of TCU blinking
The maximum “take-off” time limitation was exceeded.
Reduce speed and boost pressure at least to maximum continuous speed.
ATTENTION:
The boost pressure will not be reduced automatically.
In case of exceeding the “take-of” time limits, this has to be recorded by the pilot in the logbook,
staring the duration and exact time of exceeding of limits.
