Explain the difference between MDA/H and DA/H -
MDA/H is relevant to a non-precision approach and is the minimum altitude an aircraft can descent to and remain level until the missed approach point(MAPt)
The DA/H is relevant to a precision approach. There is no level flight involved, an aircraft flies a constant descent until reaching the DA/H, which is the missed approach point, from which it must follow the missed approach procedure if unable to land.
For take-off alternate, destination, en route alternate and destination alternates the weather forecast must cover a period from -
one hour before to one hour after the ETA.
Take-off minima without take-off alternate:
The basic rule is that an aircraft can take-off provided that, in the event of an emergency, it can -
Therefor, the take-off minima may be governed by the -
Land again at the same aerodrome and commence the instrument approach procedure.
Landing minima
If the prevailing conditions are below the landing minima of the current aerodrome the aircraft may not take-off, since it will not be able to conduct the instrument procedure in order to land during an emergency. In this case the aircraft will need a -
