# When should I start my Descent?

I use this web page when planing my flight to work at desent

I always use this. And start my decent at around 150NM.

Multiply your altitude by 3, divide by 1,000 speed at 140knts decent at 2000 vs. the number you get is how many nautical miles out you need to start your decent!

I like to view FlightAware or FlightRadar24 to see when an airplane starts their descent at a particular airport. For example, I generally see planes descending into KSFO at 125nm away.

I usually descent when Iām about 100NM away. gives me room to fix my errors if I make some

I ussially start descending at 150nms out, gives a lot of time to descend and slow down my descent of speed it up. Just a tip :), Iām sure thereās other ways people do it and descent calculators out there. Donesnt hurt to give them a try.

I normally descend halfway through the flight to give myself more time to prepare for the landing

Wow this video is 8 months oldā¦ I have been doing a video every day (actually everyday, even on christmas) for almost 9 months now tooā¦

-250 VS!? Thatās insane! In real life Iām pretty sure itās around -1800 VS. the more time at cruising altitude, the less faster you can get to you destination.

Hi, Swiss I will send you a PM can you answer please
Thanks!

I for example: ALT 18.000, 18x3= 54 nm you should start to descend at 54 nm to dest. Other example 30.000, 30x3= 90nmā¦ always mult my altitude per 3

Facepalm. Infinite Flight sets the VS automativally to 250 when You change the altitude.

I use a trick that works every time. Take your flight level, and divide it by 3. Then, if youāre in any 777, add 15. If you arenāt, add 5. This is how far you start your descent. Then, as youāre descending, adjust your VS to stay on a 3 degree glideslope. As a general idea: Donāt go over -2400, and 500 knots ground speed is approximately -2400. If youāre cruising over 500 knots, add 5-15 nm depending on how fast you are. As you descend, go cruise down to FL280. At FL280, if your airspeed is under 310, keep it. If it is over, slow to 310. At FL180, do the same thing with 290 KIAS. At 400 knots ground you should be -2100. 300 knots, -1600. Aim to be around FL180 when you hit 55 nm out. Then descend below 10k at 30 nm out.

If only you were in an SBD Dauntlessā¦Oh wait! HEY GU-

It really depends on how you want to descendā¦Want to drop like a rock or a feather? You can even start descending an hour out or 15 minutes out (not recommended). What I do is descend at a rate where Iāll perfectly arrive at the airport with just only one descent rate. For an exampleā¦ Iām at FL380 and the airport is 0 MSL and 38 minutes away. I just descend -1000 VS. Simple!

ahem news flash, IF isnāt real life. Can someone else confirm this?

News flash, I said that IF sets the VS to Ā±250 fpm when You fumble with the Altitude when airborne. I said that You can change that, since itās not practical. Descent rates vary and Iād recommend to check out topics linked here.

Ahem, another news flash, it might not be, but simulators try to achieve as close to real life as possible. And Iād say that IF physics are almost 1:1.

usually I multiply my altitude by 3
EX: 37,000 * 3 = 111nm
so when Iām missing 111nm I start the descent but I can get off 140nm so I do not get too much over the airport

a detail when you start the descent with 240 kts and -2000 vs and then comes slowing down
