So do pilots step climb in real life?

for larger/heavier aircraft and long flights yes.

Thanks! Isn’t this contradictory to the 4,000ft separation guidelines after FL290 and FL310 though?

Where did you hear it should be 4000ft vertical separation?

Above FL290 RVSM only requires 1000ft vertical separation. Non RVSM would be 2000ft, although you would have to really go out of your way to find non RVSM airspace these days.

I read it here.

I meant 4,000ft between odd / even levels.

As in FL290, FL330, FL370, FL410
FL310, FL350, FL390 etc.

So I’m not sure why it’s possible to fly FL360, FL380, FL34 etc.

I see, so 4000ft between levels to ensure 2000ft between traffic going in opposite directions.

I don’t know why it doesn’t take account of RVSM - pretty much all airspace is RVSM now. Perhaps it needs updating? I would suggest you ignore it and use the guidance posted by @Tom_Grollman above. It is entirely possible to fly at FL360/380 etc.

Boeing 787-9 and the route is:


EKCH DCT CH360 DCT D218E DCT EGABA DCT MITSI DCT VALDI/M085F340 DCT NADMA/N0487F360 DCT YZU DCT YNY DCT FOLDY DCT GLASR DCT SKYKO DCT WOODI DCT WASRA DCT HELZR DCT KARFO DCT CASDA DCT DODVE DCT R0654 R0586 KSEA


Speed: M 0.85/ 320 Knots Airspeed. Cruise Altitude FL370.

If only this could be programmed into AP for those overnight flights…

In-Flight Assistant by John Goering

Check it out in the App Store. Essential item IMO for long hauls.

BUT:

There’s also this feature request

IF assistant comes in clutch - don’t know how I’d do the long overnighters without it. I will say, it would be very nice to have it “in-app”, but at the moment, the best way to do it is definitely IF assistant.

Sorry, I should have been more specific.
How many people on board? Cargo? Are you very heavy?

Your altitude should be FL380 btw. (EKCH-KSEA is west bound)

Example:
315 passengers, 5000 kg cargo, 70000 kg fuel
Your TOW is 228000 kg/Airplane load 79%

Climb to FL360 VS 1700, 245 kts to 10000 ft, then 310 kts. Cruise M 0.85

After 4-5 hours climb to FL380 VS 500

So to answer you question: When you are at around 50-60% load you can climb to FL380
