What kind of pumps are usually used on transport aircraft as tank pumps (boost pumps) of the fuel system?
low pressure pumps / centrifugal pumps
How is the wing tank ventilation of a large aeroplanes arranged and what is the function of this type of ventilation?
- Ram air is picked up for ventilation.
- The ram air is guided through a surge and vent tank at the wing tips and vent lines into the tank.
- Ventilation avoids an excessive build up of positive or negative pressure inside the fuel tank.
- The use of ram air helps to avoid vapour build up at high altitudes.
What is the reason of flight deck window heating?
It is
- to provide (better) elasticity (2)
- to avoid ice formation and fogging. (2)
If the fire warning of an engine indicates an engine fire, what is the pilots action for fire extinguishing and what is the resulting extinguishing system configuration/action?
- The pilot will push the respective fire extinguishing button (e.g. A320) or will pull the respective fire handle (e.g. B737).
- Due to this the extinguishing is prepared (e.g. closure of engine fuel valves) and the extinguishing bottle is armed.
Describe an engine fire warning
Warning =
bell +
individual engine fire warning light
How many extinguishers must be provided for the main engines and the APU and other combustors by the fire extinguishing system of a large aeroplane (CS25)?
- The extinguishing system
- must provide one single-shot system for APU, burning heaters, and other combustion equipment.
- must provide two adequate dischargers for any main engine installation.
Describe an engine fire extinguishing process:
Step one:
pilot prepares extinguishing by arming the system (push fire extinguishing button or pull extinguishing handle)
Step two:
release extinguishing agent (by pushing the discharge switch or turning the handle)
(two steps, 2 points)
What will happen if the maximum pressure of the fixed installed oxygen bottle is exceeded?
oxygen is discharged overboard
What means "diluter-demand" concerning the flight deck oxygen mask?
When this mode is selected, the mask provides
oxygen mixed with ambient air,
and only when inhaling.
Name the operational modes of a flight deck oxygen system
normal (diltuter-demand) (1)
100% Oxygen (1)
emergency (100% Oxygen, constant flow) (2)
Passenger Oxygen system:
Describe the operation of an oxygen generator
The generator starts if the mask is pulled.
In the generator a burning process generates oxygen for passenger use.
Once initiated, the process cannot be interrupted.
How is the passenger oxygen system activated if oxygen generators are used?
- The passenger oxygen masks are provided by releasing (drop down)
- if the cabin pressure altitude exceeds the limit or when the system is activated by the respective switch in the flight deck.
- The system is "armed" by releasing the passenger oxygen masks.
- The oxygen supply is initiated by pulling one of the generator's oxygen masks.
List the correct actions that are required to get automatic deployment of ground spoilers after landing touch down (auto spoiler) and to retract the spoilers
- during approach, in-flight prior to landing: speed brake lever in ARMED position
- after touch down, extension : load on landing gear shock strut (compression) and wheel spin up
- for retraction: speed brake lever in DOWN position
A cabin door of a large transport aeroplane (e.g. A320) is used as an emergency exit.
Describe its features and operation
The door is marked at the outside and has a sign "exit" at the cabin side,
door handles are at the cabin side and at the outside,
as a large door at a hight of more than 6 ft, it is equipped with a slide,
the slide is automatically inflated when opened in "flight"-mode
slide inflation is arranged by the help of nitrogen expanding from a self contained slide inflation bottle.
