What is the job of the proximity sensing system PSS
This is the system that consists of proximity sensors, proximity sensing electronic unit PSU, proximity switches and micro switches DPSS monitors the aircraft stores, ground spoilers, thrust levers, parking brake, flat position and sequences the landing gear
What does the PSEU monitor on the landing gear
The nose doors, position of the landing gear, up locks and unlocks
What happens to the nose wheel steering and the anti-skid after takeoff
The PSEU disables the nose wheel steering and anti-skid system.
What activates the nose wheel steering and anti-skid systems upon Landing
How is the main landing gear held in the down position?
The strut actuator have locking mechanisms that lock the gear in the down position
What is the maximum gear retraction speed
What would you do if on take off the landing gear lever would not go up
This would occur if the solenoid lock or PSS malfunctioned. Use the down lock release button next to the gear handle to manually override the solenoid lock.
What is the maximum speed to extend the landing gear
What powers the main landing gear auxiliary actuators during manual gear extension
Hydraulic system number two
How are the tires protected against an overheated wheel or break.
The main Wheels have for fusible plugs in each tire. If the tire is overheated, the plugs melt and the tires deflate to prevent the tire from bursting.
What is the speed limitation for the tires.
182 kias ground speed is the speed limit
What is the minimum speed the anti-skid is operational
10 knots, below this it does not operate
When would a" to low gear" rotation aural warning be heard.
When any of the three landing gear is not down and locked, the iaf is less than 190 kias and the radio altimeter read less than 500 feet AGL
What are the four areas that have fire and overheat detection.
.jet pipe and pylons
. Main landing gear
What two areas have smoking detection systems
. Cargo bay
What ducting is contained in The Jet zone.
14th station 10th stage bleed air ducting are contained in in this zone.
What does a fire extinguisher bottles contain
Halon and pressurized nitrogen
How many Loops are used to detect a fire or overheat the condition of the APU
Two Loops of the same design as the engine loops.
Where are the Apu fire detection Loops located
The loops are around the inside of the Apu enclosure
What is used for Fire Protection in the cargo bay.
2 Fire bottles in the AFT equipment Bay and 2 smoke detectors in the cargo bay
How many squids does the Apu fire bottle have.
What is the extinguishing agent in the cargo fire extinguisher bottles
Where is the fire extinguisher located on the flight deck
Behind the co pilot seat. It is a Halon fire extinguisher
How can the fire Bell on the flight deck be silenced
By pressing the master warning switch light
Which areas only have overheat protection
Main wheel wells, jet pipe and pylon areas.
Which areas of the aircraft are anti-iced
. Wing leading edges
. Engine cowls
. Air data probes
. Windshields and flight side windows
How will the ice detector know when the aircraft has exited ice conditions.
When did the ice conditions, the ice detector electronically heats the probe for 5 seconds during each 62nd cycle after hitting the probe if it does not accumulate any more ice, then the indication is removed
After the ice detector detects ice and the wing and cowl anit-ice systems are turned on, how does the ice warning change.
It changes from an Amber ICE ECAS message to an advisory green ice message
Where did the wings and cowls get bleed air for anti icing
The 14th stage bleed air out of the engine
What is the normal position of the 14th stage isolation valve
What is the purpose of the 14th stage isolation valve switch light
This valve allows both wings to be anti-ice from a single 14th stage engine source
Is the engine nose cone anti- iced
Yes by engine oil
Which position will the cowl anti-ice valve fail
The valves fail in the open position
How many heaters are in the pitot static probe and where are they located
There are two heaters in each probe and there is one in the base and another in the head
Are the forward Flight Deck windshields anti iced
Yes, anti-ice and also the defogged / demisted
What would happen if a windshield or window started to overheat
The overheat protection would remove power from the affected surface
Will the windshield tests work when the windshield switches are in the off position
What is the purpose of the spoilerons
The spoilerons aid the ailerons to provide greater role response at lower speeds
How are the ailron, elevator and Rudder Services moved
Through the controls the flight deck, control movement and transmitted via cable and or push rods to the power control unit that will hydraulically moved the surface
How many PCUs are on each aileron
How are the sproilerons moved
Hydraulically, but electronically controlled by fly-by-wire
How many PCUs power the rudder
How many degrees will the Rudder move
25 degrees both direction
What is the purpose of the yaw dampers
They improve directional stability and turn coordination. If these oscillations were not corrected by the YDs it could cause dutch roll.
How many PCUs are provided for each elevator
How does the horizontal stabilizer mechanically move
Two electric motors drive a screw Jack, which moves the horizontal stabilizer
When the inboard flaps are extended, how is the air directed over the flaps
Spring-loaded leading-edge vanes automatically extend when the flaps are deployed.
What is the job of the flight spoilers
They provide speed control and lift dumping
What is the degree range of the flight spoilers
Any position between 0 to 50 degrees
When is the take-off configuration warning system armed
When the aircraft is on the ground
How is a jammed elevator corrected
The jammed elevator PCUs will be overridden by the other two PCUs
What is done to correct a Rudder Cable Jam
The pilot just needs to apply increased Rudder pedal Force. The other two PCUs will override the jammed PCU.
What is the source of supplemental oxygen for the flight deck
An oxygen cylinder supplies the three oxygen masks on the flight deck
Where is the flight-deck oxygen bottle located
The bottle is located under the cabin floor near the front right
What are the 3 modes of the flight deck oxygen masks
. Normal diluted demand: ambient air is mixed with the oxygen.
. 100% pure oxygen
. 100% continuous flow under pressure.
What is the fully charged pressure of the flight-deck oxygen bottle
Where is the oxygen service panel located
The right side of the forward fuselage
How many passenger masks are on each side of the cabin
Three on the first officer's side and 2 on the captain side
How many times can the oxygen generator be used
Why should a person not touch the oxygen generator
Because it can reach temperatures of 500 degrees Fahrenheit or 260 degrees Celsius
What are the components of the portable oxygen system
. PBE protective breathing equipment
. Portable oxygen cylinder
. Portable mask
What is the duration of the passenger oxygen once it is activated
Approximately 13 minutes.
