Multi IFR take-off minima question
I'm studying for IREX and having problems with take off minima questions.
My understanding is: for single engine IFR a/c always use 300' and 2km vis
For multi engine IFR a/c (such as OZY, not 2 pilot), OCTA with no IAP, use LSALT and 5km vis, taking into account airfield elevation.
or... if there is an IAP use the approach landing minima, taking into account airfield elevation, runway in use due wind and the possiblity of subtracting 100' with the correct QNH.
Does this change if taking off from a controlled radar aerodrome?
When would a multi engine a/c such as OZY use the 300' and 2km vis minima, if ever?
I keep getting these questions wrong and I can't see my error. If someone could please help me out with this it would be much appreciated.
