Re: Why QNH when coming into an airport and not QFE?

I love these kinds of debate because they are like religion. The chances are that nobody has ever changed their views on QNH/QFE because they read something on an internet forum.

I believe in the god of QNH. I believe in it for three reasons:

1) Most places that you fly in the world, QNH/QFE are not recognised, you'll get a single Altimeter setting which corresponds to QNH.

2) Some places you will land are sufficiently high that you can't physically set QFE

3) Thousands and thousands more people bust airspace by departing or arriving at an airfield with the QFE set, than have hit the ground in VMC because they couldn't do the maths associated with QNH->QFE.

I will add a side order to my 3. The UK Military are utterly bonkers for occasionally controlling transiting traffic in MATZs on QFE. Even foreign military laugh at them for it. Don't believe any nonsense about needing to separate circuit traffic from transiting traffic, that is what transponders and radar are for, and the rest of the world manages beautifully.

There. I've said it now.

Even the French, who generally don't use QFE, produce helpful visual approach charts with circuit altitude and height shown, like this:

Shame the CAA/Pooleys/AFE don't follow suit.

I think we should tackle 'Track Up' versus 'North Up' now! ;-)

I believe in the god of North Up (right up until I use Track Up)... :tongue:

We did that quite recently, though (albeit rather tamely).

Some other possibilities:

- Landing aircraft floating in ground effect
- Whether an IMC rating is enough to fly IFR safely
- Bomber circuits
- Landing fees over £10 - reasonable or unreasonable
- Carb heat to cold on final(s) - or leave hot?
- PPL training quality/effectiveness
- Flying at night and over water in a single

and my personal favourite:

- 'The Impossible Turn'

I'm sure we can think of some other classics - and I don't think it's fair to deprive the newer members of the experience just because some of us older farts have been round the loop a couple of times.

There's an ongoing discussion in the main forum on whether to buy a Rockwell Commander or an Arrow. (Or, as some inevitably argue, something else altogether.) Feel free to chip in there!
