talk about glass is half empty, Course 201 will all validate
I stand to be corrected, but I seriously doubt any course has gone right through without losing some people!!
The 60% quoted by DtyCln may be a bit high but some people will fail so I would get ready to find somewhere to flog some dodgy mugs!!
As for the length of time taken after finishing training, according to CAP744 you must have commenced the unit training plan within 6 months of finishing the approved training course (ie the college).
So there are some people who were on my course who have just started the Area course who will have lost the ADV/ADI rating come the end of the Area section...unless of course the 6 week OJT period is counted as having commenced an aerodrome unit training plan in which case I don't know how long they've got.
People on old style licences who held an ADC rating apparently must have "exercised the privileges of their licence" within 5 years or else they lose it, so I don't know why you've got it on your licence DtyCln, but I don't know if it would be valid should you try to use it. But it really is all a mystery to me!!
