# Descent Rates for Commercial Planes

I use a SimBrief to Infinite flight converter and all flight plans I’ve ever generated always involve 3000+ ft/min descent paths (and 2000+ ft/min at lower alt). Is this realistic? I always thought it was a little steep, but honestly I dont know.

The FPLtoIF descent rates are a bit steep. I usually calculate my own TOD to avoid this.

same lol. i even developed a formula for quick-fire calculations

I usually use 2000 to 10000 ft and then 1800

Anywhere from 1,000 to 3500 FPS. It all depends on your cruise, and when you want to come down/when tower tells you to come down.

A 3 degree descent is a bit over 5 times GS. Depending on the A/C you may need spoilers.

FLPtoIF has gave me decent rates of 4K+ all the time with altitude holds at weird altitudes. FL287, FL183, ect. There’s also a couple times where after the TOD, the next waypoint is the destination it self with a VS of 8,000 fpm.

Usually just start your descent a couple minutes shy of your TOD with a goal of reaching a certain waypoint at a certain time. I know there are a few descent calculators out there.

Well, it depends on many factors (traffic is a mayor one). Descent rates can go up to 4000 feet/min but can also well be 1500feet/min or less.

Tower never tells you to come down. Ever.

Do share, Ryan

I normally use 1500fpm on a normal descend (that is not too slow and not too fast) and i use 2000fpm when i have to expedite my altitude change

I normally graduate the VS. So above FL250 I use -2500, from FL250-FL120 I use -2000 and below 12000ft I use -1500 which I reduce down to about -700 when on final.

-2000 To -3500 FPM depending on speed/winds/microbursts(not in game)/etc, as I learned in flight school for American Airlines.

I go 1500-2000

You should try this.

Me parece un ángulo de descenso muy pronunciado y creobque esto genera molestias a nuestros usuarios asi que en mi caso siempre lo inicio 20 minutos antes de llegar a destino y dependiendo si se tiene ATC en ese momento

((ΔFL)(gs))/((60)(ROD)) = d

No unit change required. Just take numbers straight out of the app
FL-flight level(ft)
gs-ground speed (kts)
ROD-rate of descent (ft/min)
d-distance (nautical miles)
