There would be a possibility of a fully automatic landing: Shortly before dying, pilots would need to
- perfectly program the FMS/FMGC
- Arm Land/ILS
- Lower gear (or not, then it would be a crash landing)
- select autobrake (or not, then it would roll over the runway end)
Complete nonsense!
ad 1) now that can be done
ad2) arming the ILS (I assume you mean arming approach mode) gives authority to the nav recievers - any beam of the preselected freq would cause the aircraft to turn or go up/down. Don't ever try it in real life. One of my instructors on the A320 did it, thinking the plane would fly FMS to destination and the intercept the ILS by itself - well, he told me he was barely able to save the plane from going into a high speed stall when the thing recieved something at high level.
ad 3) I truely don't know what would happen if you lowered the gear at FL 350 doing M .80 - the doors will be gone, for sure! Then the transsonic aerodynamics - I'd say it will be interessting!
ad 4) You will overrun depending on design of the autobrake - all the ones I know will switch off at slow speeds when antiskid becomes unavailable (around 20kts)...
Dream on boy-
No pilots = certain death!
