Task E. Air Carrier Operations

Question 1

How to recognize a turbine failure?

Answer 1

A turbine engine failure occurs when a turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion.

Question 2

What is the purpose of having thrust reversal?

Answer 2

It temporarily deviates the aircraft engine thrust to act against the forward travel of the aircraft, providing deceleration.

Question 3

Sea level to 12,500

Answer 3

No oxygen required

Question 4

12,501 to 14,000

Answer 4

Required by the required crew if over 30 minutes at this altitude

Question 5

14,001 to 15,000

Answer 5

Required to be provided and used by the required flight crew

Question 6

15,001 to 25,000

Answer 6

Must be provided for every occupant

Question 7

25,001 to unlimited

Answer 7

Required to satisfy the above and an additional 10 minutes for each occupant

Question 8

At FL350

Answer 8

If one pilot leaves the cockpit, then the other must utilize supplemental oxygen unless he has a quick donning mask

Question 9

At FL410

Answer 9

Each pilot must be on oxygen at all times

Question 10

Effects of oxygen deprivation?

Answer 10

Above 10,000: the crew may begin to make errors in judgment, mental alertness diminishes.

Above 15,000: collapse and unconsciousness are not uncommon (hypoxia)

At 40,000: death will occur in approximately 8 to 12 seconds

Question 11

What are the causes of depressurization?

Answer 11

Depressurization of the aircraft cabin as a result of structural failure, pressurization system malfunction, an inadvertent crew action or a deliberate crew intervention.

Question 12

How is depressurization classified?

Answer 12

It’s classified as explosive, rapid, or gradual based on the time interval over which cabin pressure is lost.

Question 13

Types of depressurization:
Structural Failure

Answer 13

Failure of a window, door, or pressure bulkhead for example, or in-flight explosion. An in-flight explosion may be due to a system failure, dangerous cargo, or a malicious act consequential on such as an explosive device onboard.

Question 14

Types of depressurization:
Pressurization system failure

Answer 14

Malfunction of some part of the pressurization system such as an outflow valve.

Question 15

Types of depressurization:
Inadvertent system control inputs

Answer 15

Accidental or incorrect activation of a critical pressurization control.

Question 16

Types of depressurization:
Deliberate act

Answer 16

A drastic measure but one which an aircraft captain might consider, for example, as a way of clearing the cabin of smoke.

Question 17

What is control reversal?

Answer 17

Control reversal is an adverse effect on the controllability of aircraft. The flight controls reverse themselves in a way that is not intuitive, so pilots may not be aware of the situation and therefore provide the wrong inputs; in order to roll to the left, for instance, they have to push the control stick to the right, the opposite of the normal direction.

Question 18

What are the responsibilities associated with being an ATP?

Answer 18

Authority, Responsibility, Sound Decisions, Awareness, Mentoring

Question 19

What is the purpose of use Safety Management System?

Answer 19

The purpose of ASAP is to prevent accidents and incidents by encouraging employees of certificate holders to voluntarily report safety issues and events.
