Aviation Oxygen Systems Quiz

What is the primary purpose of escape masks in continuous flow O2 systems?

At what pressure are oxygen cylinders typically considered empty?

What is the primary method of oxygen supply to the crew and passengers in aircraft?

What is a common symptom of hypoxia?

What is the time of useful consciousness at 40,000 feet MSL?

What type of compound, when ignited, produces oxygen?

What are the two types of flow used in O2 systems?

What is the primary purpose of forcing oxygen into the lungs under pressure?

Operating Continuous Flow O2 Systems

To operate continuous flow O2 systems more efficiently, consider factors such as escape masks, rebreather plumbing, rebreather masks, and escape bags.

Oxygen Cylinder Pressure

Oxygen cylinders are considered "empty" at 200 psi.

Oxygen Supply Systems

Oxygen is supplied to the crew and passengers through portable or permanent systems using bottled O2 or tanked O2.

Symptoms of Hypoxia

Symptoms of hypoxia include blue lips, impaired judgment, headaches, and sleepiness.

Time of Useful Consciousness

At 40,000 feet MSL, the time of useful consciousness is approximately 15-20 seconds.

Sodium Chlorate

Sodium chlorate, when ignited, produces oxygen and is usable for 5-10 minutes.

Flow Types in O2 Systems

The two flow types used on O2 systems are demand and continuous flow.

Cockpit Regulators

The two types of regulators in the cockpit for crew usage in the event of an emergency are Pressure and Demand regulators.

Forced Oxygen Saturation

Forcing oxygen into the lungs under pressure ensures saturation of the blood, regardless of the altitude.

Oxygen Bottle Construction

Newer designs of oxygen bottles are constructed from materials such as carbon fiber and aluminum.
