Comprehensive Coverage: Air Navigation, Meteorology, Air Traffic

Management, Communication Procedures, Aviation Law, and Human Factors

• What is the primary objective of air traffic control service?
• To minimize pilot workload
• To prevent collisions between aircraft
• To provide weather information
• To increase fuel efficiency

Rationale: The main purpose of ATC is to ensure safety by preventing

collisions between aircraft and maintaining orderly flow of air traffic.

• What is the transition altitude in most ICAO member states?
• 10,000 feet
• 18,000 feet
• 24,000 feet
• 36,000 feet

Rationale: The standard transition altitude is 18,000 feet, where aircraft

switch from QNH to standard pressure setting (1013.2 hPa or 29.92 inHg).

• Which ICAO Annex covers Air Traffic Services?
• Annex 2
• Annex 6
• Annex 11
• Annex 14

Rationale: ICAO Annex 11 details standards and recommended practices

for Air Traffic Services, including ATC, FIS, and alerting service.

4. The QNH setting provides altitude above:

• Mean sea level
• Mean sea level
• Ground level
• Pressure altitude

Rationale: QNH is the altimeter setting that indicates aircraft altitude

above mean sea level when on the ground. 2 / 4

• Which of the following is a primary radar limitation?
• It cannot detect non-reflective targets
• It requires a transponder
• It operates only below 10,000 feet
• It uses ADS-B technology

Rationale: Primary radar depends on reflected signals; non-reflective or

stealthy objects are not easily detected.

6. The phonetic pronunciation of the letter “W” is:

• Whiskey
• Whiskey
• White
• William

Rationale: According to ICAO phonetic alphabet, “W” is pronounced

“Whiskey.”

• What is the standard pressure lapse rate in the atmosphere?
• 0.5 hPa per 100 ft
• 1 hPa per 27 ft
• 1 hPa per 50 ft
• 1 hPa per 100 ft 3 / 4

Rationale: Atmospheric pressure decreases approximately 1 hPa for every

27 ft increase in altitude.

• Which class of airspace provides IFR and VFR separation?
• Class G
• Class B
• Class E
• Class F

Rationale: Class B airspace provides separation for both IFR and VFR traffic

to ensure maximum safety in congested areas.

9. The purpose of a SID (Standard Instrument Departure) is:

• To simplify arrival procedures
• To control enroute separation
• To provide obstacle clearance during departure
• To allow visual separation

Rationale: SIDs ensure safe climb gradients and obstacle clearance after

takeoff until reaching the enroute phase.

• When is “MAYDAY” used in radio communication?
• For urgency situations
• For weather updates
