Sample Fire Protection questions with answers
Three questions from the free preview. Think of your answer first, then open the explanation.
1.How many fire detection loops does each engine have?
- A.One continuous loop
- B.Four, one per zone
- C.Two (loop 1 and loop 2)
Show answer and explanation
Correct answer: C. Two (loop 1 and loop 2)
Each engine detector assembly has two elements forming loops 1 and 2, monitored by fire detection cards and an AFOLTS card.
2.In normal dual loop operation, when is an engine fire warning given?
- A.When one loop detects fire for 10 seconds
- B.When both loops detect fire
- C.When either loop detects fire
Show answer and explanation
Correct answer: B. When both loops detect fire
Both loops must detect the condition. If a loop fails a test, AFOLTS changes to single loop operation using the good loop.
3.What is AFOLTS?
- A.Alternate fire override logic test switch
- B.Automatic fire, overheat and logic test system
- C.Aft fuselage overheat limit and test sensor
Show answer and explanation
Correct answer: B. Automatic fire, overheat and logic test system
The AFOLTS cards process loop signals, apply the dual/single loop logic, give the indications and test the system.
