What is the cruising altitude rule

Can anyone help me with the cruising altitude? please and thank you.

VFR up to FL180

What that says about 4000-foot intervals above FL290 only applies with non-RVSM airspace, which is fairly rare these days with advanced instrumentation, etc.

The odd for 360-179 and even for 180-359 works for almost anywhere you’ll find yourself.

I still don’t get it sorry

If your magnetic heading is 360 to 179, fly at an odd flight level^ (e.g. FL310, FL330, FL350)

If it’s 180 to 359, fly at an even flight level (e.g. FL320, FL340, FL360)

It doesn’t need to be more complicated than that.

^(If IFR, for the nit pickers who would inevitably clutter it up.)

ok thanks for the help

Bumping this as I see many pilots on expert cruising at wrong altitude.


When going east, cruise at an odd altitude
When going west, cruise at an even altitude

360-179 magnetic heading, odd flight level.
180-359, even.


Do you know why those numbers are on top of the plane?

Those are their Altitude relative to his in Flight Level. For example, if he’s at FL 80 (8000ft) and someone was at FL 100 (10000ft) it would have a +20.


@DiamondGaming4 in the US Flight Level doesn’t begin until 18000, this varies by country but generally FL180 and above is what you will see referenced in terms of Infinite Flight.
