Dudley,
Another thing that's missing here is the British attitude to the rest of the
world. They're an island in size but a continent in approach to life. And
they don't like foreigners even more than Americans don't. They don't like
things that weren't invented here and, in fact, have an entire organization,
the Civil Aviation Authority, who enforce that idea whenever possible. The
number of aircraft that are certified for aerobatics in the US, but not in
the UK is staggering. I dunno, maybe physics really IS different here.
They do things the way they want to, sod the rest of the world. The issue
of the range of the Kollman window just isn't a concern over here as
explained above, so I can see why no one would take that into account
(unless Brit Kollman windows have a greater range, I don't know)

BINGO!! Understanding the QFE question requires the understanding that all
anticipated destinations are below the limit parameters of the Kollsman
window....which is correct enough....but like most regulations, the way
it's
written is just plain nuts!!!!
Why the hell the powers that be would put in a QFE option without
explaining
that it's tied directly to the Kollsman parameters on the altimeters is
beyond me. I must know a hundred pilots who think it's an available option
anywhere!!! :-))

It's funny about things like this. I've been reading everything I can find
on the use of QFE, even that American Airlines had tried having their
first
officers monitoring a QFE altimeter with the Captain using a standard
altimeter setting on final approaches, (which I understand is no longer
the
case BTW) and there is absolutely nothing out there that specifies the
limiting parameter for QFE due to Kollsman range limits on the instrument
for airports outside the instrument parameters.
It's amazing that the governing agencies who write this stuff just assume
that sooner or later all of us will just figure out that only airports
under
3K feet are eligible for the QFE option. Interesting!!!
I have to admit, it's basic enough, but for someone reading the
regulations,
the assumption is that a QFE setting is available at all anticipated
destinations. I haven't found a reference anywhere that explains QFE as
available only within the Kollsman range. Understanding the regulation
seems
to require a prior knowledge of the Kollsman limits to understand the
situation completely, which in many cases causes much misinterpretation of
the QFE options.

how can a

I bet it can't. The highest point in England is 3210' and
Scotland only goes to 4400'.
