221
Is the anti-skid system capable of modulating pressure to individual wheels?
No, it can only remove brake pressure to the wheel pairs on the left or right mains
222
What protection does the anti-skid system provide while in-flight?
When the gear handle is down, the anti-skid system removes all brake pressure to the wheels to provide touchdown protection until a wheel begins rotating > 20 mph.
223
What effect would a failure of the nose wheel squat switch have on the anti-skid system?
Locked wheel sensing will release brake pressure anytime a wheel decreases to below 12 mph. The end result will be that you will have no brakes below 12 mph and will have to use the emergency brakes to stop the aircraft.
224

243
What is the source of bleed air?
6 bleed air ports on the 8th stage compressor

Why should you wait till the nose wheel is on the ground prior to deploying the drag chute in high crosswinds (>15 kts)?
The drag chute will increase the tendency to weathervane into the cross wind.
253
How do you release the drag chute after deployment?
Push the handle forward to the stowed position
254
Why would you want to release the drag chute?
To avoid the potential of the drag chute being ingested by an engine.
To avoid damage to the drag chute from dragging it along the ground
To avoid damage to the airport from snagging items with the drag chute
255
When would you want to release the drag chute?
When the aircraft has slowed to the point it is not in danger of over run and when the drag chute is loosing aerodynamic effectiveness.

270
What is the normal air source for pressurization?
8th stage bleed air from the air conditioning system
271
What is the air source for emergency pressurization?
8th stage bleed air, this bypasses the air condition system
272
Will the position of the bleed valves or air conditioning valve affect the emergency pressurization?
No
273
How would you activate the emergency pressurization?
There is a manually operated emergency pressurization valve in the emergency controls.
274
How is cabin altitude maintained?
Outflow valves vent cabin air
275
How many outflow valves are on the falcon?
2
276
Where are the outflow valves located?
The rear pressure bulkhead
277
What powers the outflow valves?
They are electro-pneumatic. The automatic controller requires 115 VAC non-shed and pneumatic air generated using bleed air. Manual control is entirely pneumatic.
278
What is the function of the manual pressurization controller (cherry picker)?
It overrides control of the outflow valves.
279
Can you use manual pressurization controller (cherry picker) if the pressurization controller is in the AUTO mode?
Yes, the cherry picker directly changes the position of the outflow valve. However, as soon as you release the cherry picker, the automatic pressurization controller will resume control of the valve.
280
What is the effect of placing the pressurization controller into the MANUAL mode?
Electrical power to the controller is removed. Control of pressurization is dependent on pneumatic input from the manual pressurization controller.
281
What is the air source for the manual pressurization controller (cherry picker)?
It is a 3 way valve and receives input pressures from the cabin air pressure (higher pressure) and the outside air pressure (lower pressure).
282
With the pressurization controller in the AUTO mode, and the aircraft on the ground, what position will the outflow valves be in?
When in ground mode, the controller will seek to maintain a 500' per min rate of change to match the outside air pressure, this will result in the outflow valve remaining partially open. A takeoff mode closes the outflow valve when the right throttle is advanced past 80-85% N1.
283
What limits the cabin from overpressurization?
Overpressure-releif valves open the outflow valves when the pressure differential reaches 8.5 psi.
284
What limits the cabin pressure from being lower than outside?
The outflow valves only limit air flow out of the cabin. The valves will not prevent air from flowing back into the cabin if air pressure is higher outside.
285
Why is the nose cone pressurized?
Required by the rotary inverters and some weather radars require it.
286
Is the nose cone pressurized in all falcons?
Only the early models and models with rotary inverters and some models of weather radars.
287
What is the function of the emergency depressurization (DUMP) switch?
It opens the outflow valves to allow the cabin to depressurize. It should be used if the cabin will not depressurize or last case in the event of an emergency to increase air flow to clear smoke and fumes from the aircraft.
288
Does the emergency depressurization (DUMP) switch require electrical power?
Yes, it is powered by non-shed DC. The automatic controller is AC powered so the dump switch is powered independently of the controller. The dump switch directly powers the open solenoid on both outflow valves.
289
When would you use the emergency pressurization (Source of air)?
When the normal source of pressurization from the air conditioning system is insufficient.
290
Is the emergency pressurization air conditioned?
No, it is hot bleed air.
