urgents help in answering the following qs?

[tonymmho]

1) How can V-NAV Be Selected? (a) Alone (b) only if A/T selected (c) A/P and F/D Selected.
2) Mach trim is initiated by : (a) A/P trim motor (b) Mach/Speed trim motor (c) Electric trim motor
3) How INS obtain vertical calculation ?
4) FMS using NAVAID for what purpose?
5) For aircraft to be certified for automatic landing; an Autothrottle system is : (a) mandatory (b) depends on operator in slow speed (c) not mandatory.
6) When can the FMS be engaged with the Autothrottle: (a) before take off (b) only after take off (c) A/P and F/D engaged
7) what is a versine signal attenuated with? (a) decrease in altitude (b) increase in altitude (c) increase in airspeed

Many thanks in advanced.:confused:

Which type?

CP

[aveng]

Sounds like generic basic questions!

1) probably (c) - needs f/d or a/p
2) b)
3) with accelerometers (3 axis)
4) navigation updating
5) Probably a) - crew workload related
6) a)
7) c) versine lifts the nose during a/p turns, so needs to be linked to speed ie. more speed = more lift, less versine reqd.
:ok:

Thanks aveng for answering the qs. Going to sit for my EASA Part 66 B2 exam soon. Great help. Thanks again.
Can you further help in the following qs:
1) Deviation of 8.33 khz offset frequency in VHF? (a) permitted (b) not permitted
2) Fail Passive on Autoland : (a) Produce no out of trim and A/P is not completed. (b) Produce no out of trim and A/P is completed (c) Produce out of trim and A/P is not completed.
3) If an ILS receiver fails Before localiser capture: (a) autoland continue (b) revert to cat II (c) autoland discontinue.
4) If an ILS receiver fails After localiser capture : (a) autoland continue (b) revert to cat II (c) GA is initiated.

Many thanks in advanced.:confused:

1) do you mean channel spacing? - not sure might be an easa thing.
2) Dont understand "complete" - do you mean coupled? ie. a/p engaged. I try to think of a/p operation as what would you logically want it to do if it fails, ie. be as soft on operation as possible and not try to drive a/c into ground or pitch up or something stupid. So consider which answer would be best.
3)/4) ILS rcvr is critical for autoland - not sure but probably 3)=(c) don't know if it its refering to a triple redundant system or not because 1 out 3 failing what not be as critical and would probably set the system to land 2 only.
Sorry not very helpful:ok:

Autoland does not need Autothrottle on some a/c types . It is not mandatory.

Autoland does need an independant Landing System for each Autopilot . It is possible but rare for a/c to use Micrwave Landing Systems in place of ILS and there is a plan to introduce a GPS based Landing System at some time in the future ( trials are already under way ) .

Yes the BA Airbus fleet is fitted with MLS. The trials are completed, and approval is due for Cat 3 at LHR this month.
Big advantage is much closer spacing on finals with no beam distortion.

Already in use in Sydney - late model QF 737-800's have the new LS panels and are in use.

I'm a bit worried that someone going for a B2 licence doesn't know the answers to these very basic questions. :uhoh:

[JEMAVION]

TONYMMHO,
Have you ever thought about learning how nav and auto flight systems actually work; and then you can answer these questions from experience? Obviously you prefer to find the answers to specific questions which you can then answer parrot fashion, thus acquiring a qualification you don't deserve
