What would be the recommended flight level range for the following distances?(I know that it depends on the direction of flight +/- 2000/4000ft.1 mile to 100 miles =100 miles to 500 miles =500 miles to 2000 miles =2000 miles and up =[div align=center][link:members.cox.net/fstimes/wetimage.html]Click Here For Weather Image of the Day

Tooo vague...Really what ever alt. provides for the most economical in some cases or the fastest in other cases, or the most scenic in other cases...;-)

Joshieca,Greatly depends on type of aircraft. For jet aircraft, with which I am most familiar, a general rule of thumb would be distance divided by 10 plus 5 (for FL).For example, 100nm / 10 = 10 + 5 = FL150 (then varied up or down for direction of flight). Very rough gouge but will put you in the ball park for alitude. A quick climber (Boeing product vice airbus or RJ may use dist/10 + 7 or so. Your don't need very long at cruise (in some cases only minutes)to make it an economical profile.Once you get to stage lengths of 250+nm then the aircraft will be flown up in FL300+ range. Winds and enroute turbulence will then play a role in determining how much you deviate from the economical altitude.Altitude is much less critical with respect to range flying for recip engines.Kevin in CYOW
