Oxygen A320 – Air – DGCA Question Bank For Politics

#1. On which ECAM page could the flight crew check the exact pressure of the oxygen cylinder?

The PRESS page.

The DOORS page.

The COND page.

The STATUS page.

#2. What is indicated by a missing green thermal plug during an exterior preflight?

An oxygen system overpressure or thermal discharge.

This is normal indication, the green thermal plug only appears if the oxygen cylinder is low.

The crew oxygen bottle is empty.

An external fire discharge has been activated.

#3. Approximately how long are the passenger oxygen generators able to produce oxygen?

15 minutes.

20 minutes.

25 minutes.

30 minutes.

#4. What is the main difference between the crew and the passenger oxygen system?

There is no difference: both are served by oxygen cylinders.

Crew is supplied from an oxygen cylinder; passengers are supplied by chemical oxygen generators

Both the crew and passengers are supplied with oxygen from chemical oxygen generators

The crew has an oxygen bottle for an emergency back-up supply.

#5. What is the purpose of the CREW SUPPLY push button?

When selected to ON, it supplies oxygen to the Captain & F/O only (jumpseats are not supplied)

In case of low cylinder pressure it allows the crew to tap into the passenger oxygen system.

When selected to ON, it allows the flow of low pressure oxygen to the crew‟s masks.

#6. What happens when the mask is used with the selection at 100% position?

Mask is supplied with diluted oxygen on demand.

Mask is supplied with undiluted oxygen on demand.

Mask is supplied with undiluted oxygen continuous flow.

Mask is supplied with diluted oxygen on demand.

#7. At approximately what cabin altitude should the passenger oxygen masks drop?

10,000 feet (+100, - 500 ft)

12,500 feet (+ or - 500 ft)

14,000 feet (+0, - 500 ft)

15,000 feet.

#8. What does an amber OXY on the ECAM Doors mean?

The crew supply switch is turned off and/or oxygen pressure is less than 400 psi.

The crew supply switch is turned off

Oxygen pressure is less than 650 psi

Oxygen pressure is less than 300 psi.

#9. Illumination of the SYS ON light is an indication that:

The crew must depress the MASK MAN ON pb in order to deploy the masks.

Electrical power has been sent to deploy the masks, either manually or automatically.

The crew oxygen cylinder is empty.

All of the passenger masks have deployed.

#10. There are oxygen generators in each aircraft‟s galley.

True

False

#11. What will depressing the guarded MASK MAN ON pb accomplish?

A signal is sent to the chemical oxygen generators to start the flow of oxygen to the masks.

It manually sends a signal to open the oxygen mask doors.

Both are correct.

#12. When does passenger oxygen flow start?

When the oxygen doors open.

When the mask is pulled toward the seat.

When the oxygen button is pushed

When cabin altitude exceeds 14,000 ft'
