I am experiencing communication difficulties through flying in a storm. The meanings of the Aeronautical Code signals were assigned by ICAO. • QAA to QNZ – Assigned by the International Civil Aviation Organization (ICAO). Q-codes still work when HF voice circuits are not possible due to atmospherics and the nearest vessel is one ionospheric hop away. Since, only stations of the Aeronautical Service will have available copies of the Aeronautical Code, it should not be used in communications with stations of other services unless it is known that the station concerned is familiar with the code. The ICAO Q Code 1. Since amateur communications are without charge, this Q-code would not make sense. For Q-code assertions or queries which only need to be acknowledged as received, the usual practice is to respond with the letter "R" for "Roger" which means "Received correctly". I am flying in and out of cloud and at flight level/altitude ... Report your flying conditions in relation to clouds. 2. Q Codes for Aviation. The first set comes from the ITU civil series QRA through QUZ. means "Shall I decrease transmitter power? They are part of a larger set of Q Codes allocated by the ITU-R.The QAA–QNZ code range includes phrases applicable primarily to the aeronautical service,[2] as defined by the International Civil Aviation Organisation. (See also Responses to a radiotelegraph Q-code query or a Q-code assertion may vary depending upon the code. For the letter used in place of Q in some Inuit orthographies, see Morse code is now very rarely used for maritime communications, but in isolated maritime regions like Antarctica and the South Pacific the use of Q-codes continues.

(What should I set on the subscale of my altimeter so that the instrument would indicate its height above the reference elevation being used? The Aeronautical Code signals are radio signal codes. For those Q-code assertions that merely need to be acknowledged as understood, the usual practice is to respond with the "QRO" redirects here. Are you experiencing communication difficulties through flying in a storm? For Q-code queries that need to be answered in the affirmative, the usual practice is to respond with the letter "C" (Sounds like the Spanish word "Si").
The codes QAA–QNZ are assigned by the International Civil Aviation Organization (ICAO); QOA–QQZ by the Maritime Mobile Service and QRA–QUZ by the International Telecommunications Union (Radio-communication Sector).
