This website is based on ICAO (International Civil Aviation Organisation) Document 4444 - Procedures for Air Navigation Services - Air Traffic Management, Chapter 12, Phraseologies and Annex 10 Vol.II Aeronautical Telecommunications.
The purpose of this ATCwiki is to familiarise the members of IVAO.aero with the use of standard Phraseology (Aviation English) for on-line flying and to be a solid basis for its future official use by those who endeavour a professional career in Aviation.
The original text and document structure has been adapted as much as possible to be understood by the broad public, without changing its meaning.
Some items have been slightly altered for IVAO, whilst trying to stay as close as possible to reality.
Aviation English is a language on it's own, with it's own structure, vocabulary etc... comparable to a programming language.
Use standard expressions as much as you can, so that Pilots and ATC from different nationalities and backgrounds can understand what you want them to do or what to expect.
Keep communication clear, compact, simple... to reduce the possibility of confusion or misinterpretation to a minimum.
Focus on 1 topic at the time when learning Aviation English.
1. Try to USE CORRECT PHRASEOLOGY YOURSELF, be a good example before wanting to teach others
2. To help someone learn phraseology, FOCUS on 1 (ONE!) MISTAKE she/he makes all the time and correct it
3. THE AIM IS FOR EVERYONE TO IMPROVE STEP-BY-STEP, NOT TO DISCOURAGE PEOPLE
1. It is very UNPROFESSIONAL : you block other people's transmissions
2. Discuss about WHAT is RIGHT, NOT WHO. Use chat, forum,...etc. but NOT the frequency!
3. Find out WHAT went WRONG and HOW you can PREVENT IT from happening again!
1. A pilot MUST ALWAYS DO what he has READ BACK
2. ATC MUST ALWAYS CHECK if a READBACK is correct
3. IF ATC does NOT CORRECT a pilot's READBACK when it is wrong, the WRONG READBACK is considered as a MISTAKE of ATC!
Take your time and enjoy the reading!
