Engines and APU.

Question 17

What kind of calls can be done from the cabin interphone system?

* Passenger announcements.

Question 18

What is the purpose of lavatory temperature indicator?

Answer 18

(3.5.11.2) A temperature indicator located inside the lavatory cabinet to the extinguisher records the temperature in case of a waste bin fire.

Question 19

When will you use the manual toilet shut-off handle?

Answer 19

(12.5.1.4) All lavatories are equipped with a manual toilet shut-off handle (see picture) and the handle must be pulled if the flush cycle is not closed automatically.

Question 20

Are there any differences between our Legacy, Sky and Sky+ interior when it comes
to the manual shut-off handle?

Answer 20

Legacy and Sky are the same.

Sky+ There is no manual toilet shut-off system with this lavatory. Failure of the automatic flush system will necessitate that the toilet bowl be blocked with a large soft item to stop the air leak.

Question 21

Where is the lavatory water supply/shut-off selector valve located?

Answer 21

(12.5.2.1) Located in the cabinet, below the sink.

Question 22

Explain the emergency lighting system?

Answer 22

(12.9.2) The emergency lighting system provides direction to exit locations and illuminates the egress paths inside and outside the airplane, and the duration is at least 20 minutes.
The system is normally controlled by a switch on the flight deck and is placed in the ARMED position prior to flight. In this position, all interior and exterior emergency lights illuminate automatically if there is a total loss of electrical power. The pilot can illuminate the emergency lights at any time by placing the flight deck emergency lights switch to ON.
The emergency lights switch located on the AFT CCM panel at the AFT entry door can be used to bypass the flight deck switch and illuminate the emergency lights, including floor proximity lights, regardless of the position of the flight deck switch.

Question 23

Where is the emergency lights switch located in the cabin?

Answer 23

Aft attendant panel

Question 24

What is a dedicated assist space and where is the location of these?

Answer 24

(11.2.2.3)

All exits are designed to have a dedicated assist space either forward and/or aft of the door. Cabin crew must grasp the exit assist handles and position themselves correctly in the assist spaces. They must not allow themselves to be pushed out the exit and must not interfere with evacuating passengers.

(12.2.1.1)

Near each entry door is a dedicated assist space.
The dedicated assist space is located adjacent to the door opening. During an emergency evacuation it is important that the cabin crew grasp the assist handle and place themselves in the dedicated assist space to ensure they are not blocking the exit in any way. When the assist space is against a vertical surface (such as galley, a partition or lavatory) keeping your heels and upper back pressed against that surface helps to ensure that you stay clear of the exit path.

Question 25

What is the purpose of flight deck sliding windows?

Answer 25

(12.3.9)
The flight deck sliding windows can be used as an emergency exit of “last resort”. The left flight deck sliding window can only be opened from inside the aircraft, but the right side sliding window can be opened from both inside and outside the aircraft.

Question 26

Can both flight deck sliding windows be opened from outside?

Answer 26

Right window can be opened from both inside and outside, but left can only be opened from inside

Question 27

What does a galley module contain?

Answer 27

(12.4.1) Individual galley modules may contain ovens, waste containers, water boilers, storage/servicing trolleys, sinks and stowage space to aid in food preparation and dispensing. Galleys are equipped with electrical power and water systems. Lighting controls are located on the galley electrical panel. A galley vent system keeps the air fresh.

Question 28

What are the drain guidelines for galley water?

Answer 28

(12.4.4)

The galley Water shutoff valve has two positions only: On and Off. Try to stop a leak here by selecting the Off position, and if unsuccessful, re-position to On, and prepare to drain the water tank of its contents.
Allow cold and hot water to run continuously into the sink of both AFT lavatories; the water will be lead out of the aircraft through a heated drain mast underneath the hull of the AFT part of the aircraft.
The reason for emptying the water tank through AFT lavatory sinks is the risk that water may freeze, and potential blocks of ice may damage vital aircraft parts.

Question 29

What are the drain guidelines for lavatories?

Answer 29

(12.5.3)

• In every toilet, the relevant valve for this is called water supply selector valve.
The general rule is to attempt to stop the leak by shutting off water supply. If unsuccessful, the next step will be to open water supply again, and to empty the potable water tank. Another general rule, of course, is to always communicate with Flight deck crew what has happened, and not to start the draining process before you have their permission.

The aircraft’s only water tank has a capacity of 235 litres. The water tank supplies both the galleys and the lavatories (including the vacuum toilets) with water.
Under the lavatory sink, the water supply selector valve has four positions: SUPPLY ON, (the normal position); OFF, FAUCET ONLY and TOILET ONLY. Attempting to stop a leak in any lavatory water supply, select the OFF position. If unsuccessful, re-select the SUPPLY ON position, and prepare to drain the water tank of its contents.

The physical draining of an aircraft’s potable water tank, should be done as follows:

Allow cold and hot water to run continuously into the sink of both aft lavatories; the water will be led out of the aircraft through a heated drain mast underneath the hull of the AFT part of the aircraft.
The reason for emptying the water tank through AFT lavatory sinks is the risk that water may freeze, and potential blocks of ice may damage vital aircraft parts.
There is a separate drain valve in the forward lavatories of our B737. This is not to be opened in air. The valve handle is located further inside the cupboard; is only to be handled by technical staff on ground.

Question 30

How many lavatories are there onboard, where are their locations and what are their names?

Answer 30

3
Lavatory A (LAV A) = FWD left-hand side Lavatory D (LAV D) = AFT left-hand side Lavatory E (LAV E) = AFT right-hand side
