## im dumb....

i know this is kind of a dumb question but when atc says for example FlightLevel320 what altitude would that equal, and how do you figure what flight level translates into ft? thanks in advance

32000 feet.. 310= 31000 feet... 290=29000 feet etc etc... get it? Heaven forbid MS flight simulator used "angels" to calculate feet might really confuse some people.

ps...you're only dumb if you never ask the question.

okay, thanks for the explanation newguy!

If you want to be really technical about it, it's slightly different than than. FL310 is 31000 feet indicated, with the altimeter set to 29.92 for the air pressure, which more than likely is not the actual air pressure. But it's easier to have all the high altitude aircraft set to 29.92 and have all of them off their actual altitude by the same amount than to be constantly changing the pressure setting throughout the flight.

Do tehy really do that. Every high altitude airplane puts there altimeter at 29.92. I never new that, i thought they just updated the altimeter ever half hour.

onto a flight level number, to know what altitude it is.

So if someone mentions Flight Level 120, for example, all you have to do is add two zeros onto that in your mind, to come out with 12000 or 12,000 feet. :)

It's that simple. Just add two zeros.

Yes. In the USA, the transition altitude (TA) is 18,000 ft. The transition level (TL) is FL180. You'd hit the TA while ascending through 18,000 ft and the TL while descending through flight level 180. At TA, you set your altimeter to 29.92 and when you hit the TL you set your altimeter to what ATC tells you. That's the way it works in the real world. However, I don't get to fly up that high. ;)

In other parts of the world, the transitions are at different altitudes. Some as low as 3-6000 feet. Flight Sim uses the USA standard across the world, much to the displeasure of many.
