Having worked at a number of schools and not once been presented with anything remotely resembling company SOPs*, either written or verbal, one feels slightly pleased that the job is as yet largely free from the usual bureacracy endemic within many workplaces these days. It is one of the few positive things still going for this particular flying job that an instructor is permitted their own quality time with a student to acheive the 'objective' in a manner he/she deems fit. That is why we have a universally agreed assessment in the form of a skills test.
Airline language such as SOP's seems to be creaping into the world of the PPL more and more. A large part of it is down to the fact the instructors wish they were flying heavy metal instead of spamcans which is very sad indeed. Probably the same instructors who fly airliner style circuits, prefer teaching VOR tracking over real VFR navigation, sit polishing their shoes in between lessons ready for their next airline interview and spend the rest of their time thinking up increasing ways to overcomplicate something that's really quite simple.
When will people learn: if it ain't broke, don't fix it?
VFE.
*I have however read a few FOBs.
