Here's another example. If you are flying at 11,000 feet, you report this altitude as “one one thousand”. If you are flying at 11,500 feet, you say “one one thousand fife hundred”. These rules are valid for altitudes under 18,000 feet.
Alpha, Bravo, Charli, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, PaPa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu. Pilots pronounce numbers similar to regular English, with a few exceptions: The number three (3) is pronounced “tree.”
The ICAO phonetic alphabet has assigned the 26 code words to the 26 letters of the English alphabet in alphabetical order: Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu.
Pilots mostly pronounce numbers as in regular English but with a few exceptions. Zero (0) is always “zero,” not “oh.” Three (3) becomes “tree.” Five (5) becomes “fife.” Nine (9) becomes “niner.”
Aviators often speak “pilot English” to avoid miscommunications over radio transmission. “Tree” for instance, means three, “fife” is the number five and “niner” means nine, says Tom Zecha, a manager at AOPA. The variations stemmed from a desire to avoid confusion between similar-sounding numbers, he says.
As the pilot monitoring, you will chime the bell to notify the flight attendants when you are above 10,000 ft. That lets them know that that can begin service. As captain, you would normally call for sterile cockpit when going below 10,000 feet.
The most well know of these is the code 7700. This is used to indicate an emergency of any kind. A pilot will enter this when in an emergency situation - either instructed by ATC after declaring an emergency or without communication if there is no time.
A—'TEN THOUSAND, FIVE HUNDRED FEET. ' B—'TEN POINT FIVE. '
The phrase "five by five" can be used informally to mean "good signal strength" or "loud and clear". An early example of this phrase was in 1946, recounting a wartime conversation. The phrase was used in 1954 in the novel The Blackboard Jungle.
Code 7600 is the code for a loss of radio. If a pilot's radio goes out during a fight, they can enter 7600 into the transponder. Then they should proceed to their intended airport following a standard landing plan. Pilots should be extra careful and on alert for other aircraft around them in the sky.
Series 00 — Code 0000 is available to any State for general purposes. (Codes 0001 to 0077 are available for domestic purposes.) Series 20 — Code 2000 is to recognize an aircraft that has not received instructions from the air traffic control units to operate the transponder.
07: Aircraft connection by maintenance. 08: Aircraft connection by miscellaneous, traffic, marketing flight operations, ground handling, cabin services, etc. 09 (SG): Scheduled ground time less than declared minimum ground time.
Transponder codes
This allows easy identification of aircraft on radar. Codes are made of four octal digits; the dials on a transponder read from zero to seven, inclusive. Four octal digits can represent up to 4096 different codes, which is why such transponders are sometimes described as "4096 code transponders."
The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet.
Airlines typically assign the return flight number as one digit higher than the outbound flight. For example, JetBlue has a flight from JFK to LAX that's JBU523. When it returns to JFK, the flight number is JBU524. Generally, the lower the flight number, the more important that route is to the airline.
10-4 is a way of saying “message received” in radio communications. It's also used as a way to “you got it.”
An example RST report for a voice transmission is "59", usually pronounced "five nine" or "five by nine", a report that indicates a perfectly readable and very strong signal. Exceptionally strong signals are designated by the quantitative number of decibels, in excess of "S9", displayed on the receiver's S meter.
V1 is the maximum speed at which a rejected takeoff can be initiated in the event of an emergency. V1 is also the minimum speed at which a pilot can continue takeoff following an engine failure.
"We had understood and read back 'descending to 10,000. ' Phraseology contributed to this incident." "To correct future problems like this, the altitude should be given in the form of 'ten thousand' or 'eleven thousand', instead of saying 'one-zero', or 'one-one-thousand.
For example, as mentioned above, conspicuity code 1000 is used in the EU (pronounced "one thousand" in accordane with Regulation 2016/1185) for Mode S equipped aircraft that will remain within Mode S airspace until reaching their destination. These aircraft can be reliably identified by their Mode S callsign.
VHF 121.5 and UHF 243.0
Very high frequency (VHF) 121.5 and ultra high frequency (UHF) 243.0 are “guarded” frequencies reserved in the aircraft operations band exclusively for emergency communications and notifications. Generally, civil aircraft are VHF radio equipped, and military are UHF radio equipped.
0000 — A generic code that is not assigned and should not be used. 1200 — VFR aircraft. The default code for all flights–if you aren't asked to set anything else, you should set 1200. 7500 — Hijacking. 7600 — Voice radio failure.
For example, "1200" in the USA means that the flight is flying under Visual Flight Rules (VFR) and is not typically in direct contact with ATC. "1200" is a shared code so you may see many aircraft transmitting it at the same time in a given area.
Code 7400 may be displayed by unmanned aircraft systems (UAS) when the control link between the aircraft and the pilot is lost. Lost link procedures are programmed into the flight management system and associated with the flight plan being flown.
