SmartCockpit Fokker 50, Manual

SYSTEM OPERATION 

Flight control lock 

The flight-control lock should be engaged during taxiing and parking. After setting the flight-
control lock, move the control column slightly forward and bring the ailerons and rudder to 
the neutral position; check the flight controls are locked. When releasing the lock, be aware 
of flight control movement due to wind. The PF should keep his feet on the rudder bar while 
the PNF should hold the control wheel. 
 

CAUTION: 

Applicable for aircraft equipped with LSAS. If the flight control lock is engaged 
while the flaps are traveling the system will see this as a wrong input during 
the test phase of the LSAS, this might cause a non reset-able FAULT of the 
LSAS. 

Flaps 

Normal operation 

The flaps are hydraulically operated and the flap position is controlled by a flap selector. 
Operating time from up (0) to 35 or reverse is approximately 15 seconds. 
 

Alternate operation 

The flaps are electrically operated and controlled by the alternate flap control switch. 
Alternate flap operation inhibits normal flap selection. To avoid nuisance alerts select the 
normal flap selector to the indicated flap position. Operating time from up (0) to 35 or reverse 
is approximately 180 seconds.
