Here are a few questions from oxford school regarding instrumenation which, actually, are not that hard but i prefer to ask for advise before submitting my assessment.
So enjoy it !
1) With a fully equipped FMS aircraft the following selections are usually utilised in flight :
a- LNAV only
b- LNAV and VNAV
c- VNAV only
d- LNAV and VNAV but not simultaneously
I'd answer d), cause if i have well understood lnav is used during cruise while vnav is more concerned with climb&descent, so the use of both modes cannot be simultaneous. Is that right?
2) If the radio altimeter fails :
a- height information disappears
b- aural warning given
c- radio alt flag, red lamp, and aural warning given
d- radio alt flag and red lamp activates
I'm quite hesitating between c) and d).
3) If an aircraft fitted with two FMSs, the pilots' displays show contradictory information. What mode of FMS is in use?
a- independant mode
b- dual mode
c- single mode
d- separate mode
Answer a) ?
