SU4: PMDG 777, 737, IFly MAX8 Random Engine Spikes

ISSUE DESCRIPTION

Since SU4,On MSFS2024 (NOT HAPPENING PRIOR) I noticed annoying “spikes” of engine power on climb out and decent below 15,000 happening at random. It’s happening on the PMDG 777, 737, and IFly MAX8 at the very least.

Important note:

  • This is happening to at the very least myself and my friend. We both have the Honeycomb Bravo Throttles.

- Moved the throttles the length of my Honeycomb Bravo while the spikes were occurring. No change. Additionally, with AT engaged, no N1 changes while moving the levers up and down the axis. So, I am very confident this is NOT a hardware issue.

  • FMC menu item A/T Manual override is set to “NEVER” so, i know it’s not my hardware.
  • Nothing in control settings that show evidence of multiple throttle levers bound

FREQUENCY OF ISSUE

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

3/5 flights since SU4 (NO ISSUES PREVIOUSLY)

REPRODUCTION STEPS

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

Just a “normal” flight… I took off out of IAH flying to ORD in all three planes. Setup was “the usual” via the FMC. LNAV/LNAV utilized per usual…. PERF page setup as usual…. The spikes happen below 15,000 but NOT always… no issues before SU4.

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

Im having this exact same issue. I use the Velocity One yoke and throttle quadrant however. My flight was from KHOU to KMEM in the PMDG 737-800.

Like you, I have all assistances off. I ran the sim without any addons or mods to be sure. Looks just like your video.

Seemed to occur between apprx 7000-18000 ft, and it would be one side or the other. Not at the same time. It immediately shut off Autothrottle, but would also continue while controlling manually.
