ARS ARS Fueling and Deicing Operations 1 — Questions and Answers
Question 1: What is the minimum safe distance a fuel truck must maintain from an aircraft's engine inlet during fueling operations?
- 5 feet
- 10 feet (Correct answer)
- 15 feet
- 25 feet
Correct answer: 10 feet
Fuel trucks must maintain at least 10 feet from engine inlets to prevent fuel vapor ingestion and fire hazards.
Question 2: Which grounding procedure must be completed FIRST before beginning aircraft fueling?
- Connect the fuel hose to the aircraft
- Bond the fueling equipment to the aircraft (Correct answer)
- Open the fuel truck valve
- Check the fuel quantity gauge
Correct answer: Bond the fueling equipment to the aircraft
Bonding the fueling equipment to the aircraft before any fuel flow eliminates static electricity buildup that could cause sparks.
Question 3: What type of fire extinguisher is required to be present and accessible during aircraft fueling operations?
- Class A water extinguisher
- Class B CO2 or dry chemical extinguisher (Correct answer)
- Class C halon extinguisher
- Class D metal powder extinguisher
Correct answer: Class B CO2 or dry chemical extinguisher
Class B extinguishers rated for flammable liquid fires are mandatory during fueling because aviation fuel is a flammable liquid.
Question 4: During aircraft deicing, Type I deicing fluid is primarily used for which purpose?
- Anti-icing to prevent new ice formation
- Removing existing ice and snow from aircraft surfaces (Correct answer)
- Lubricating deicing equipment nozzles
- Protecting ground crew from cold temperatures
Correct answer: Removing existing ice and snow from aircraft surfaces
Type I fluid, typically applied hot, is designed to remove existing ice and snow from aircraft surfaces before departure.
Question 5: What is the holdover time for deicing fluid?
- The time required to complete a full deicing application
- The estimated time the fluid remains effective after application (Correct answer)
- The minimum time an aircraft must wait before takeoff after deicing
- The time needed to flush the deicing truck lines
Correct answer: The estimated time the fluid remains effective after application
Holdover time is the estimated period during which deicing fluid prevents ice accumulation after application, varying by fluid type and weather conditions.
Question 6: Which area of an aircraft is considered a 'no-spray zone' during deicing operations?
- Wing leading edges
- Engine inlets and exhausts (Correct answer)
- Fuselage top surface
- Tail horizontal stabilizer
Correct answer: Engine inlets and exhausts
Engine inlets and exhausts are no-spray zones because deicing fluid entering engines can cause damage or affect engine performance.
