Gums,
You can just turn the automatics off and hand fly it if you want to.
Least accurate and highest risk method though.
In increasing order of accuracy (and reducing workload and risk):
- Hand fly using raw data. Cigar in mouth and amusing hat donned. It is mandatory to remind the white faced FO on the way down that you have 38,000 hours and nothing beats experience.
- Hand fly using flight directors programmed with something useful. Pointless.
- Automatics in conventional modes (hdg and v/s). Like a basic 737.
- Automatics using track and FPA mode.
- Automatics using NAV (FMC lateral) and FPA mode.
- Automatics following a pre-programmed and checked database lateral and vertical flight path.
All though require monitoring of the raw data - because it is still an NDB approach. Just some methods are more accurate than others.
