I am more than happy for the thread to drift back to WWII training.
In answer to one of your questions, the AFU was to enable aircrew who had learned their trade overseas to experience UK / Europe flying conditions, such as barrage balloons, black outs, fog, varying terrains etc.
I have had a very quick look at some other Air Bomber log books to see if there is any information on the various exercises and, as a possible start point:
B2 - B4 may relate to daytime bombing (with the numbers possibly relating to a specific target)
B5 may relate to nighttime bombing
CE may relate to "Combined Exercise" (ie long distance navigation and bombing [Bullseye])
MR may relate to Map Reading
I will have another look later to see if I can find more detailed information.
If you need any information on training or the loss of the aircraft, please let me know and I will see what I can dig out for you.
Regards
Pete
