Flptoif question

does Climb Profile 250/320/85 mean the rate you climb at?


Those are speeds not rate of climb. Basically it means go 250 to 10000, 320 to FL280 and then Mach .85 to cruise


Also please someone explain these it literally is my first time using FLPtoIF.

Basically what rate to climb at.

I mean… should be pretty self explanatory. Flight level is altitude, block fuel is total fuel, etc.

I mean, a lot of these are self-explanatory things…

Elevation: how high the airports are MSL.
Planned runway: runway to use for takeoff and landing.
Current weather: METAR for the airport and the time of publication.
SID/STAR: self-explanatory.
Aircraft: self-explanatory.
Flight level: how high you’ll ultimately end up at.
Block fuel: fuel.
Plan distance: self-explanatory.
Flight time: self-explanatory.
V-Speeds: V1, V2, and VR, which aren’t available.
Climb profile: refer to Drummer’s explanation.
Descent profile: Drummer’s explanation, but for going down.
Passenger count: self-explanatory.


Climb at your discretion…


Ohhhhhh. That makes more sense. Thank you! :)

If you follow all instructions stated, climbing to FL400 shouldn’t be a problem.

To add on, there’s many Infinite Flight tutorial videos found on YouTube that help cover this stuff if you need further assistance.


Idrk why you don’t know what climb rate to use when you kinda answered your own question in this message:


You can climb at your discretion…

However, if you need figures, here’s what i follow most of the time depending upon the type & weight of the aircraft!

Altitude Vertical Speed IAS
Upto 10,000ft 2500 VS 240 - 250 IAS
10,000ft - FL280 2200 VS 290 - 310 IAS
FL280 - FL430 2000 - 1800 VS M 0.78 - M 0.85
Generally less speed for small aircrafts such as A320/B737 & more speed for large aircrafts such as B777/B787.
