The airspeed indicator, altimeter, and VSI all use the static system, so a static blockage affects all three.
Question 53: What does 'VFR NOT RECOMMENDED' in a weather briefing mean?
- IMC conditions exist at the destination and alternate airports
- VFR flight is legally prohibited in the briefing area
- The briefer advises that conditions are not suitable for VFR flight, though the pilot retains final authority (Correct answer)
- ATC has temporarily restricted VFR flight in the region
Correct answer: The briefer advises that conditions are not suitable for VFR flight, though the pilot retains final authority
'VFR Not Recommended' is the briefer's professional advisory opinion that conditions are hazardous for VFR flight; however, the pilot in command makes the final go/no-go decision.
Question 54: In weight and balance terminology, 'arm' refers to what measurement?
- The horizontal distance from the datum to the item or station (Correct answer)
- The moment contributed by a specific item or station
- The total weight of all items loaded in the aircraft
- The maximum load capacity of a specific baggage compartment
Correct answer: The horizontal distance from the datum to the item or station
Arm is the horizontal distance measured in inches from the datum to the item, station, or center of a compartment, and it determines the leverage of that weight about the datum.
Question 55: An aircraft will always stall at the same:
- Altitude
- Angle of attack (Correct answer)
- Power setting
- Airspeed regardless of attitude
Correct answer: Angle of attack
A wing always stalls at the same critical angle of attack, though the corresponding airspeed varies.
Question 56: During a fire on the ground while starting the engine, what is the recommended first action?
- Turn off the avionics master switch.
- Continue cranking the engine. (Correct answer)
- Apply the fire extinguisher directly to the engine.
- Evacuate the aircraft immediately.
Correct answer: Continue cranking the engine.
If an engine fire occurs on the ground while starting, the recommended first action is often to continue cranking the engine. This action can draw the flames back into the engine and potentially extinguish them by consuming the excess fuel. It also attempts to start the engine and clear the fuel system, which can resolve the fire.
Question 57: Which medication class is generally considered incompatible with flight duties?
- Low-dose aspirin for cardiovascular prevention
- Standard vitamin supplements
- Antihistamines (allergy/cold medications) (Correct answer)
- Topical prescription eye drops
