Ah the famous "Stop" versus "Abort"
. discussion .
Here we go again :
Before 1977 each Country had his own phraseology ,but after 1977 (Tenerife) it was unanimously decided to remove the words " Take off" in any transmissions but the actual take off clearance, , therefore all the previous local phraseologies using the words , like Abort take off, Reject take off, Cancel take off clearance, etc, etc. were to be disregarded. Since then (and still valid today ), the Correct ICAO PANS ATM phraseology , to be used is :
[call sign] STOP IMMEDIATELY [repeat aircraft call sign] STOP IMMEDIATELY
Reasoning being is that the transmission can be stepped on by someone else and only a portion can be received , and if that part of it contains the words take off , it might be misunderstood.
Remember in Tenerife, one of the main factors was that the Pan am transmissions that they were still on the runway was stepped over and not received by neither the Pan Mm nor the controller. .
In addition we needed a standard wording , and when conducting a cultural check , most non native English pilots from emerging countries with basic level 4 would understand the meaning of STOP . Therefore STOP was chosen. and adding the word ' IMMEDIATELY" , is the standard ICAO terminology to convey urgency and repeating it twice , a standard for safety related messages.
I find it worrying that almost 50 years after this change there are apparently still pilots unaware of the changes and it looks like some ATC training academies and Flying schools still do not train the use that phraseology.
