We all discuss on this forum delays to flights, airports and travel in general.
I’ve just seen this https://www.nats.aero/discover/plane-talking/ interactive animation from NATS, the UK air traffic control service. I didn’t realise it was all so complex. This is rather good.

I have just watched the first few minute of this – quite good but one question.
When I did my PPL some years ago, Take Off was refered to as ‘ CLEARED TO DEPART (26)’ not cleared for take off. The response being (***Call Sign) – DEPARTING 26′ not ‘Taking Off’. Have we returned to the old language or is comercial flying different.
I will watch the rest of this when time permits.

BPP being a bit of a geek, it all refers to whether there is an ATC service or a FISO service in place. Commercial flying from an airport is different to GA flying from an airfield without full ATC

Fascinating, especially the stats..

Would be interested to learn similar stats for a longhaul flight. How many ATC/Pilot transmissions, average length etc etc… As for watching… err I dont think so.

Thanks for posting…

Hello BPP,

From memory from my time doing my PPL training and subsequent flying in the Channel Islands the only occasion that the words “take off” would be used in ATC communications was in the actual clearance to take off. All other instructions would use the word “departure” i.e. “after departure maintain runway heading until advised”. I think this protocol might have been introduced as part of the learnings after the Tenerife tragedy where ambiguity in the radio transmissions was a contributing factor to the accident.

If I remember correctly from the documentary, ceasing use of “takeoff” and replacing with “departure” was a result of the Tenerife disaster.
