Would you not be able to fly <FL290
- I don't know about now, but it stumped BA in 2003 and I believe the flight would had to have been conducted below FL100 as I think BRNAV was then from 100 to 290 and RVSM above, which from Venice to LGW would make for some scenic views of Nice
. On that occasion I 'helped ' the poor besieged BA manager and came back in stealth mode lying like a cheap Japanese watch, as they say.................
Anyway, back to the poor OP - yes, into the QRH and behave like a real pilot! It is actually quite enjoyable.
