there are only very few questions which I can remember…
meridian convergence – increasing with sine of latitude!?
question about great circle, rhumb line, LEB
aircraft flies above its optimum FL – effect on fuel consumption
course-scheme calculation
how does IRS compute GS
question where to find definitions / directives about airliners according ICAO Annex???? – any JAR-OPS ???? or FAR ???? (this question was my favourite one)
many meteorological questions
purpose of vortex generators
I prepared myself with "ACE-technical Pilot Interview" and "Pilots Reference Guide" but I felt myself only average prepared.
