There is a temptation to set 2 and 3 at the same value but in my opinion that is illegal.
We have no such thing as a 'split cockpit height'. Our Alert Height is 1000', above which (and I quote)
"If any of the following conditions apply:
- Master Caution Illumination
- Autopilot Disengagement
- No Flare Annunciation
- Stab Out of Trim Light
Reset the alert, continue the approach, attempt rectification, re-consider Autoland/LVO capability."
We are not talking about QRH drills like an hydraulic failure....
If below the Alert Height
"Instrument switching is NOT permitted. A go-around should be made for:
- Engine malfunctions resulting in loss of thrust
- Failure of a required airport facility
- Failure of a required aicraft system
- Continuous ILS deviation warning above 200'RA
- Any ILS deviation below 200'RA
Continuation of the approach is recommended in the event of the following:
- Engine Fire warning, without loss of thrust
- Pilot incapacitation - consider fuel, weather, diversion availability and aircraft serviceability
