Dear all,

Page 151 of BMS Dash 1 said that I should set altimeter without further instruction on how.

How to do it?

And what will happen if fail to do so?

I can still take off and land, though.

Well, I'm a bit rusty but the theory is simple.


Simplified explanation!
The air pressure tells your plane what altitude it holds above the sea.
The altimeter is set according air pressure. Usually above 5000 feet it's not really important, anyway.
When you take off is a good thing to make sure that your altimeter is set so that it reads 000000 feet.
When you set your altimeter you use either a knob or in another fighter plane that defends Europe ;), you directly set the pressure in Millibar with a keypad.
On the left-Hand Glareshield.

But I digress.

Let's say you want to approach and land on an airfield that has its runway 300 feet above sea level against the one you departed from that was (just an example throwing numbers here, ok?) 2000 feet above the sea.

If your altimeter is still set for the Airfield you departed from when you touchdown the altimeter will read minus several hundreds feet, 1700 more or less. That is if the pressure is the same as the airfield you took off from.

Well, that's when the simplified explanation gets a bit more complicated so I stop here...
In general, obviously, you want to keep the altimeter set and checked out now and then. wink

It's very hard to see, but it's a round knob on the left bottom corner of the altimeter:

IIRC, you can mouse over the altimeter and use the scroll wheel to adjust settings up/down.

While you don't need to set the altimeter at all, doing so gives you more precise altitude readings. Was it 29.92 when above 14K feet? That way, everyone at or above that altitude have the same readings, otherwise when your flight lead tells you to level off at Angels 25, you may be +/- a few hundred feet. Below 14K altitude, it is useful when doing instrument approaches. That way, you won't lawndart because you were expecting to be 800 feet higher up. Takeoffs and landings in clear weather, no need except for realism feeling.

Emotional? How about old? That Daw.. Dows, "douson" Creek reference is telling quite the story.

(Yes, me knowing that also makes me old.)

Sorry Komemiute, it is my fault.
You can spank me on this. (hope it is not too strange)
