No Graham,

Coastal Command used them too, the better to co-ordinate with the Royal Navy, etc.

Indeed, the Mossie swapped to Knots later in the war too! I went through my Pilots Notes and found a ton of guff on it and have lost my notes….my wot an exciting life I lead!!!

Knots is a far more sensible way to go anyway.

Regarding pilots notes being preproduction aircraft…not always true. Aircraft were initially issued with Provisional Pilots Notes which had no shots and then RAF Handling Squadron would complete the proper pilots notes after they had their hands on a ‘real’ service aircraft.
