I did manage to have a look at one of the Aircraft Performance training manual yesterday with one of the Integrated teachers.
It didn't look as clear as Bristol/Atlantic/Oxford, lots of text with the odd formula inbetween, black and white (out of date with the times), but quite possibly informative.
I guess it's down to how you prefer to see things presented whilst reading and I guess the college thinks "if it works, why change it".
I plan to visit Cabair at Cranfield and will have a better look then.
