ISSUE DESCRIPTION

Description of the issue: Lack of thrust. When landing, unable to perform an abort, aircraft lacks power and cannot climb.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?

All the time

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Select the Boeing 737 MAX - Asobo Studio

  2. Start flight

  3. Lacks climb power

  4. Lacks power at landing for aborts, or touch n go. Even when throttle is at 100%, engines indicate 100% as well

Did you try SU5 Beta?

"Boeing 737 MAX 8

Fixed an issue where the flight director could sometimes command the wrong pitch/bank angle immediately after turning the flight director on or when activating a flight director mode when no mode was previously active.
Adjusted FLC mode to more closely adjust for target speed.
Fixed an issue where the FMC message TAKEOFF SPEEDS DELETED could be shown in flight.
Improved Glideslope tracking to reduce pitch oscillations.
Improved autothrottle response and tracking in SPD target modes.
Improved autothrottle tracking accuracy in thrust target modes.
Fixed an error during automatic PERF INIT when the plane spawns in the air.

I’m on SU5 Beta, & the power seems slightly improved with the latest tweaks that have been made (as in your post CommonBloom)

But I too have found it pretty underpowered in the the engine/thrust dept - this is when hand-flying it without auto-throttle etc..
It just seems like you’ve got to coax it up into the air, but there again I’m not a real-life pilot of a 737-Max!

I’ve not tried it for a while as the super-sensitive trim and twitchy elevator response annoys me (PMDG 737-800 much nicer to fly), but the aircraft should be able to maintain a flaps 30 approach on the 3 degree glide slope with around 60% N1. Last time I tried to land it I had the thrust levers set well above 80% N1 and I still couldn’t keep the speed where it needed to be

Tried this aircraft last night for the first time in a while. Generally it is much improved from what it was but engine thrust is still seriously lacking.

The aircraft rolls by itself with the brakes off in idle but in order to get any kind of speed up, an N1 of at least 35-40 is needed which is unrealistic

In the air, the most noticeable part of the lack of thrust comes from approach. Fully configured on a 3 degree glideslope, around 60 N1 should be plenty to maintain the approach speed. But as can be seen from the below screenshot, I needed 77 N1 which is far too high

When you get to flaps 40, you don’t have much left. It’s been like this since a couple of updates ago. Been waiting for them to remedy it.
