1. What is the purpose of a SIGMET?
A. To provide warnings of icing for all aircraft
B. To advise of weather potentially hazardous to all aircraft
C. To provide information about VFR conditions only
D. To advise of conditions affecting only light aircraft
SIGMETs contain meteorological information significant to the safety
of all aircraft, such as severe turbulence, icing, or volcanic ash.
2. What does a METAR report?
A. Routine aviation weather observation
B. Forecast for the next 12 hours
C. NOTAMs related to weather
D. Upper air soundings
METARs are routine weather reports issued hourly for specific
airports and include wind, visibility, sky condition, and temperature.
3. What is the fuel requirement for a domestic flight under FAR Part 121?
A. Enough to reach the destination only
, B. Enough to reach destination and alternate only
C. Enough to reach the destination, then to the most distant
alternate, plus 45 minutes
D. Enough for 30 minutes beyond destination
FAR 121.639 requires fuel for destination, alternate, and 45 minutes
at normal cruise.
4. Which weather chart provides information about fronts, high and low-
pressure systems?
A. METAR
B. TAF
C. Surface Analysis Chart
D. Winds Aloft Chart
Surface Analysis Charts show pressure systems, fronts, and isobars.
5. When must an alternate airport be listed in the dispatch release?
A. Always
B. When ceiling is less than 2,000 feet and visibility less than 3 miles
at destination
C. Only for international flights
D. When crosswinds exceed 15 knots
FAR 121.619 requires an alternate when weather conditions are
below 2,000 ft ceiling and 3 SM visibility.
6. What is the definition of V1 speed?
A. Stall speed
B. Rotation speed
C. Decision speed to continue or abort takeoff
D. Takeoff safety speed
V1 is the speed by which the pilot must decide to continue or abort
the takeoff.
, 7. What does an AIRMET Sierra signify?
A. Severe turbulence
B. IFR conditions or extensive mountain obscuration
C. Volcanic ash
D. Severe icing
AIRMET Sierra relates to IFR and/or extensive mountain obscuration.
8. Which factor increases aircraft takeoff distance?
A. Cold temperature
B. Short runway
C. High-density altitude
D. Tailwind
High-density altitude decreases engine performance and increases
takeoff roll.
9. What type of approach requires the use of glide slope and localizer?
A. VOR approach
B. ILS approach
C. RNAV approach
D. Contact approach
ILS approaches use both glide slope (vertical guidance) and localizer
(lateral guidance).
10. What is the purpose of a MEL (Minimum Equipment List)?
A. To specify which items may be inoperative and still allow the
aircraft to be dispatched
B. To list maximum cargo capacity
C. To record pilot training records
D. To authorize emergency landings
The MEL allows for specific equipment to be inoperative while
maintaining safe operations.
