Pilot's Notes
Hi Danny, According to the history of the RAF Handling Squadron aircraft handling information (Pilot's Notes) was provided from the mid 30s by pilots who flew each new type. Initially parts of CFS were involved, and this task seems to have moved to several different units. In the early days the pilots flew the aircraft and then wrote handling notes, and were given access to the aircraft at the beginning of its RAF service. Notes were written for all aircraft used by the RAF (including aircraft from the USA), and latterly for Army and Naval aircraft. With the advent of Lightnings, Javelins etc Pilot's Notes were considered to provide too little information and so the Aircrew Manual arrived - a much more comprehensive document. At about this time the pilots on the squadron (who were known as 'fumblers') stopped flying the types they wrote about as it was too expensive. So maybe one of these pilots wrote the Notes - with the Phantom we wrote our own Aircrew Manual and didn't use the USN Manual.
