Surely, regarding any instrument approach, it's this simple.
- Maintain speed between Instrument Vmin and Vmax.
- Stay on the glidepath or above MDA until FAF is reached, if you can't, go around. Once visual, do what you like to effect a safe landing.
- Use the autoplilot in a sensible manner to reduce workload.
The only time these simple rules don't apply is if you're suffering a major malfunction or you've run out of fuel. People seem to be going round in circles on this forum over-complicating what should be a straightforward procedure.
Or am I missing something?
