2.15 RECOMMENDED OPERATOR MISSION TASKS
For typical mission flight, operators can do their tasks in 5 operational time frames:
•
Pre-Flight inspection of the physical condition of the turret
•
Pre-Takeoff check to prepare the turret for takeoff
•
In-Flight operation of turret while airborne
•
Pre-Landing check to prepare the turret for landing
•
Post-Flight shutdown to disable and stow the turret
Before flight, the operator
must
do a Pre-Flight inspection and make sure that:
•
the turret is correctly attached
•
purging of the turret is not necessary
•
all sensor windows are clean
Complete the Pre-Flight inspections in good time before the flight. This gives the operator sufficient time to
complete a turret purge or clean the sensor windows, if necessary. When the humidity in the turret is above the flight
limit, 1-2 hours is necessary to purge the turret. Do all other operator mission tasks at or during flight time.
