Above 1000 feet? Did you miss a zero there?

Nope. 1000-2000 are the typical figures for most airlines in the
Middle East. I could get you figures from Qatar Air and Etihaad (two
of the leading lights, not just of the region) in a few days.


I know that RVSM requires autopilot and some airlines have policies that
require autopilot for normal operations under certain conditions, but
requiring that autopilot be used above 1000 feet is hard to believe.


Ditto here, but that's the way it is. "Passenger comfort and safety"
is what's apparently at the root of this requirement.


Which airlines require this, and why?

I still can't believe the ultra-sophisticated Airbuses allow rudders
to move so much that the empennage can actually sever from the rest of
the fuselage. As omissions go, that must take the biscuit!

Having been the victim of French engineering on multiple occasions in the
past, I have no trouble believing that French engineers overlooked this. Their
objective is not to maximize safety, but to show the world how clever they are
(a rather tall order, given that they aren't actually very clever).


I beg to differ, mate. Apart from one A320 crash - a runway overrun in
Warsaw? - where the computers misread aquaplaning and didn't allow
braking, I struggle to think of an incident where computers and/or
automation caused a crash. On the other hand, I know a few instances
where the automation forfended accidents by thwarting ill-judged
premature takeoff attempts, which were an upshot of wrong loading
figures having been input, etc. There have been at least two incidents
involving Emirates A340 aircraft and one Virgin A330.

Not being a pilot, I'm utterly unqualified to enter Boeing-Airbus
debates but it does strike me that Boeing does have more friends in
the press, with its glitches getting downplayed. The dicky RA that
contributed to the Turkish crash at Schipol and the near-disaster with
the BA 747 @ Jo'burg caused by a faulty slat sensor are good examples.
If you analyze Airbus crashes, nearly every one of them has been
because of pilot error, including the Aeroflot A310 where they risibly
ended up blaming the kid on the Cap'n's seat when what really happened
was that the 3 other qualified pilots looking on within the cabin
failed for a very long time to detect that the AP had disconnected.
Most Airbus crash reports would tell you that they could've been
prevented had pilots acted correctly.

I admire the 747s and 777s and think the A340 a clunker, yet would
wager my life on Airbus's sophistication any day. It could be just me
but that's the way it is
