Q Codes & Abbreviations: DGCA Radio Telephony (RTR) questions
14 practice questions and 5 flashcards on Q Codes & Abbreviations for the DGCA Radio Telephony (RTR) exam, with 1 linked simulator. Try the samples below, then practise the whole topic.
Key concepts
Altimeter Q codes.
QNH: reads elevation above mean sea level. QFE: reads height above the aerodrome. QNE: standard 1013.25 hPa, reads pressure altitude.
Tip: QNH = Nautical Height (above sea level). QFE = Field Elevation (zero on the field).
Direction-finding Q codes.
QDM: magnetic heading to steer to the station (zero wind). QDR: magnetic bearing from the station. QTE: true bearing from the station. QUJ: true track to the station.
- QDM and QDR are reciprocals
Sample questions
Q1The Q code QNH means:
- The altimeter setting that makes it read zero on the ground
- The altimeter sub-scale setting that makes the altimeter read elevation above mean sea level when on the ground
- The standard pressure setting 1013.25 hPa
- Magnetic heading to the station
Show the answer
Answer: B. The altimeter sub-scale setting that makes the altimeter read elevation above mean sea level when on the ground QNH causes an altimeter to read the aerodrome elevation when landed.
Q2The Q code QFE means:
- The altimeter setting that gives zero height on the aerodrome (or runway threshold)
- True bearing from the station
- Runway in use
- Altitude above sea level
Show the answer
Answer: A. The altimeter setting that gives zero height on the aerodrome (or runway threshold) QFE makes the altimeter read height above the aerodrome reference point.
Q3ATIS stands for:
- Airfield Tower Information Service
- Aircraft Terminal Instruction System
- Approach Traffic Information Signal
- Automatic Terminal Information Service
Show the answer
Answer: D. Automatic Terminal Information Service ATIS is a continuous broadcast of aerodrome information.
Q4QDM is:
- True track to the station
- Magnetic bearing from the station
- True bearing from the station
- Magnetic heading to steer (zero wind) to reach the station
Show the answer
Answer: D. Magnetic heading to steer (zero wind) to reach the station QDM = Magnetic heading to steer (in zero wind) to reach the station.
