AVRO RJ - FMS with no fuel quantity indication
Problem: One fuel tank quantity indicator may be INOP.
According MEL A/C can be dispatched after dipstick. No problem with that, but:
FMS has no more performance page, no speeds, no predictions on fuel etc.
This is a logical consequence but nevertheless a nuisance.
Back to manual fuel checking etc. Not a problem with this contraption as everything to do this is at hand.
Rises the question - how is this handled in e.g. A320 or 737? More problems with the performance page, speeds etc.?
