Answer 10

The pilots have priority over the attendants and other.

Question 11

How are the galleys secured to the aircraft structure?

Answer 11

Cabin galleys are normally fixed to the seat rails with additional fasteners to the walls and ceiling so that the relatively heavy galley can withstand acceleration well above normal flight loads.

Question 12

Describe the methods of retaining cargo in the different types of cargo bays?

Answer 12

Bulk Compartments - (loose objects + living animals) - A cargo net suspended across the compartment prevents cargo from shifting when the aircraft is in flight. The net webbing is attached to anchor plates on the side walls and loop fittings on the ceilings.

Container or Pallet Compartments - Cargo to be loaded is in normalised containers or pallets (LD-3 half containers)

Question 13

How can you retract an air-stairs if main electrical power if off?

Answer 13

Air-stair can be retracted or extended with aircraft battery power or with 115 volt AC power (ground power)

Question 14

Answer 14

Escape Slides are installed at all the aircraft exits.

Question 15

Where are emergency ropes installed in large transport aircraft?

Answer 15

In civil passenger aircraft which have emergency exists without escape chutes, emergency ropes are provided. They are also fitted by overwlng emergency exits.

Emergency ropes are also fitted by the crew emergency exits. The crew may escape from the cockpit by sliding down these ropes to safety.

Question 16

What is the reason why F/A seats should fold automatically after use?

Where are they located?

Answer 16

They fold away after use so that there is more space in the cabin area

Answer 17

The seats’ internal pans are covered with a fire blocking material,

Seat cover is also aplied periodically with fire resistant substance

Question 18

Describe the two different kinds of cargo compartments used in transport aircraft?

Answer 18

1. Bulk Cargo Compartment - loose objects and living animals. A cargo net is suspended across the compartment to prevent cargo shifting in flight. The net webbing is attached to anchor plates on the side walls and loop fittings on the ceiling.
2. Container Cargo Compartments - Cargo in normal pallets or containers. Normally LD-3 half containers are used.

Question 19

Is it possible to open air stairs manually and what are the driving methods for normal operation?

Answer 19

Control circuits - consists of limit switches and relays that sequence the driving of the air stair door and air stair actuators. Control selection can be either normal powered or a manual mode.

The carriage and ladder assemblies are
driven by an electric motor driven actuator.

Question 20

At what height above ground do aircraft exits, by regulation, require that exit slides must be installed?

Answer 20

Exit slides must be installed at exits that are 1.8 meters or more above ground.

Question 21

What happens when an emergency exit door escape slide handle is put in the armed position?

Answer 21

A gritbar connects the emergency escape slide to the door attach fittings. When the door is opened, the door movement pulls the slide from the slide pack and it falls down. A lanyard then pulls the reservoir valve open which inflates the slide fully within 3 to 10 seconds.

Question 22

Describe a typical aircraft emergency exit escape path lighting system.

Answer 22

The escape path lighting is white in colour and guides passengers to an escape exit. The escape door lights themselves will be red in colour. The height of the escape path lighting system must not be greater than 4 ft.

These emergency lights are independent of the main lighting system and are battery powered.

Question 23

Detail how passenger seats are attached in the passenger cabin.

Answer 23

Passenger seats attach to tracks on the compartment floor. The tracks are extruded from the floor throughout their entire length and contain circular cut outs that receive the seat attachment fittings. They are positioned in 1’’ increments.

Question 24

How are items secured in a bulk cargo compartment?

Answer 24

A net is cast over the bulk cargo compartment and is attached to anchor plates on the walls and loop fittings on the ceiling of the compartment. This ensures the cargo is secure and will not shift in flight which would affect the aircraft’s centre of gravity.

Question 25

How are an aircraft cabin airstairs controlled?

Answer 25

Aircraft airstairs can be controlled from inside or outside the aircraft. They are actuated hydraulically through aircraft battery, APU or ground power.

Aircraft cabin airstairs also contain manual actuation if a defect occurs or for maintenance purposes.
