Is the phrase 'GO AHEAD' no longer in force???? (for pilots or ATS people)?

Question

Hi I have heard that according to ICAO ANNEX 10 VOL II AMDT 82 the phrase 'GO AHEAD' is no longer in force. The thing is that I don't have this amendment. Can anyone help me confirm this information please? I will appreciate it.

Answer 1

I don't have the amendment either, but I know the phrase has been discontinued as an invitation to read back clearance after someone took it for permission to take off.

Answer 2

It is still standard phraseology in the US, according to the 2/14/08

Pilot/Controller Glossary

GO AHEAD- Proceed with your message. Not to be used for any other purpose.

Also in the FAA's AVGO.......

Section Four - Aviation Phraseology

Go ahead - State your request  

Amdt says..

Answer 3

I think it was discontinued following the big accident where two 747s, one from KLM and the other from (i forget) collided on the runway.

the KLM pilot thought he was cleared to takeoff and smashed into another 747 exiting the same runway.

500 or so people perished
