2. Transfer Jack - Only 1 extension available
3. Mechanical

Question 2

Is there split flap protection on the Falcon 20?

Answer 2

No.

Question 3

What could the pilot do if flaps were set at 25º but when the flap lever was set to 40º the aircraft suddenly began a roll into a 45º bank?

Answer 3

Retract flaps immediately to 25º since this is most likely a split flap condition.

Question 4

What is the purpose of the Arthur Q units?

Answer 4

They provide artificial feeling by increasing or decreasing the stiffness of the flight controls depending on the speed of the aircraft.

Question 5

If the Arthur Q units fail, what should be done?

Answer 5

Slow down below 265 knots.

Question 6

How many trim controls are on the Falcon 20?

Answer 6

Four

1. Normal pitch trim
2. Emergency tail trim
3. Rudder trim
4. Aileron trim

Question 7

Which trims are on a load shed bus?

Answer 7

Ailerons, rudder and emergency trim

Question 8

When will the stabilizer trim light and horn come on?

Answer 8

The light will come at 5.5º nose up trim.

The horn will sound on the ground with nose trim at 5.5º nose up and 84% power lever angle.

Question 9

When will the big, red airbrake light illuminate?

Answer 9

When airbrakes are extended
Power lever angle is greater than 84%
Nose gear is down and locked.

Question 10

If landing with the airbrake extended what corrections needs to be applied to the landing distance?

Answer 10

1000 ft

Question 11

Manual control linkages allow the aircraft to be flown at speeds up to __________ KIAS without any hydraulic power.

Answer 11

200

Question 12

The Arthur Q master panel warning lights will come on if the AQ unit is in the ___________ speed mode with airspeed above 265 kts and vice versa.

Answer 12

Low

Question 13

If the No 2. hydraulic system fails the Arthur Q unit will automatically revert to the __________ mode.

Answer 13

Low Speed

Question 14

What does the rudder gust damper do?

Answer 14

Prevents rudder damage from wind gust when the aircraft is on the ground and both hydraulic systems are off.

Question 15

What is one caution with respect to the trim stops about using the emergency trim switch?

Answer 15

The electrical stops in the system are deactivated so it is possible to drive the trim systems into the mechanical stops. This can be avoided by watching the trim indicator scale to monitor when the trim is close to the limit.

Question 16

How does the emergency flap button work?

Note: this is not the same as a manual flap extension

Answer 16

When depressed it directs transfer jack pressure to the flaps. To use it, put the flaps in the desired setting and then hold the emergency flap button down until the flaps reach the indicated position on the FLAPS position indicator.

Question 17

What are the steps for an emergency manual flap extension? (Do not confuse with the emergency flap button extension)

Answer 17

1. Pull the FLAPS circuit breaker
2. Grab the manual extension crank stowed on the left wall of the cabin aisle.
3. Insert the crank on the reduction gear for manual flap operation
4. Turn the crank clockwise about 200 turns for 25º flap extension.
