737 climb speed

I’m just wondering what the climb speed of a 737 is, as I usually climb at roughly 2500-3000ft and I cruise at around Mach 0.78. Above 10,000 I speed up to around 300 ish and I don’t know if that’s the appropriate speed or not.

Thanks

I think 280 is mostly used on the 737 above 10,000

and mach is around .76-.79.

Someone can correct me if I’m wrong

I personally use this website to find climb charts. I find it pretty reliable to use and it has most of Infinite Flight planes.

I mimic realistic A/THR as follows (from my observation of XP11 Zibo Mod):

  • At 1000ft AGL, reduce throttle to 5% less than takeoff thrust (should normally be 80-85% N1, which is your climb thrust), lower the nose to 1000-1500 VS and accelerate to 250kt (or as restricted), retracting flaps step by step (you can either hand fly or use AP)
  • When 10kt below speed target start to gradually increase VS so that the speed stops increasing at target speed with provided climb thrust
  • When crossing 10kft:
  1. disconnect SPD if connected, you’ll be at climb thrust when disconnected

  2. lower the nose to +1000fpm VS, accelerating to around 290kt (in more complicated sims this is determined by the FMS with the cost index, in IF you can just assume a number)

  3. When 10kt below speed target start to gradually increase VS so that the speed stops increasing at target speed with provided climb thrust

  • Re-engage SPD when stablized. Adjust VS dynamically to maintain climb thrust

The key is to keep the climb thrust at a constant level.

This is what I usually do:
On a flaps 5 takeoff, I retract flaps to 2 at 180-190 knots. At 220 knots, I go clean and continue accelerating to 250 knots.
At 10000, I accelerate to about 292 knots to reach mach 0.78 by 28000 feet. This is the usual cruise speed for the 737.
