I don't know the right or wrong answer, but ...............
I would imagine that the assesor is not ultimatly concerned whether it is your last base check / IR / or IRR (the most recent would suffice). What they will be looking for is how you critique yourself. Lets face it no-one is going to fly the perfect ILS / NDB etc, etc. Are you honest enough to acknowledge your faults/ mistakes that were made, and how you dealt with them. When I answered this question I tried to think back to what my instructers used to de-brief me (particularly the IR examiner). I would advise you not to go into too much detail. Keep it brief, factual, and too the point. If necessary write it under seperate headers ;
Departure
Airways
ILS
Engine failure
etc
Remember they may ask you to describe the same flight in the ineterview, so try not to exagerate
.
Sounds like a question off the CTC form? Hope this helps, good luck.
