THR LVR position (animation) doesn't match actual thrust lever pos

Describe the bug

After calibrating the throttle (Logitech Extreme 3D Pro) using the EFB, the "LVR CLB" message on PFD keeps flashing despite throttle being at the CLB detent and "THR LVR" being shown in green on the PFD. The message keeps flashing even in CRZ mode.

To Reproduce

1. Make sure throttle is calibrated via EFB settings page
2. Operate the aircraft normally by engaging auto throttle and auto pilot as appropriate
3. Reduce throttle to "CLB" setting when commanded

Expected behavior

Expect PFD to annunciate "THR LVR" for speed mode and white "LVR CLB" message to stop flashing

Actual behavior

The THR LVR message is annunciated but LVR CLB never goes away

Additional context

Was this working before/when did the issue start occurring? Yes

Is this a problem in the vanilla unmodded game? N/A

I'm also seeing this bug - latest experimental build via installer. Saitek AV8R stick calibrated via EFB. (Custom autopilot is beautiful work BTW).

Also experiencing this on the latest experimental build via installer. TCA Thrustmaster.

Same here with Airbus throttle quadrant, even though its all set up ok. I also noticed that the PFD doesn't show that its in FLEX mode either when taking off, but shows MAN THT. In the old Custom version it used to show the FLEX and Temp. I import all my plans via SimBrief and fully set up the MCDU as well.

Same problem here. And after takeoff it appears the message "T.O. Inhibited" in red, and/or ASYM. THRUST (if I remember correctly).

To bring some light into the darkness, the animation that shows the thrust levers position is "rounded" hence less accurate than the position information we use to determine the thrust levers positions. Long story short, if the FMA shows your thrust levers are not set correctly, it's right.

maybe this is why my auto throttle seems to not work despite placing the throttle detent clearly where it's supposed to be. Had some very weird flights at 450+ kts. It really messes with your ability to successfully change altitude too.

Hi, could you also try to post your ThrottleConfiguration.ini here? I think this issue might also be related to the range for the detents

[ghosh9691]

@Saschl , here's the throttle config:

[throttle_common] reverse_on_axis = false

[throttle_axis_1] reverse_low = 0.000000 reverse_high = 0.000000 reverse_idle_low = 0.000000 reverse_idle_high = 0.000000 idle_low = -1.000000 idle_high = -1.000000 climb_low = 0.520000 climb_high = 0.520000 flex_mct_low = 0.840000 flex_mct_high = 0.840000 toga_low = 1.000000 toga_high = 1.000000

[throttle_axis_2] reverse_low = 0.000000 reverse_high = 0.000000 reverse_idle_low = 0.000000 reverse_idle_high = 0.000000 idle_low = -1.000000 idle_high = -1.000000 climb_low = 0.520000 climb_high = 0.520000 flex_mct_low = 0.840000 flex_mct_high = 0.840000 toga_low = 1.000000 toga_high = 1.000000

@MisterChocker , I don't think that's an accurate statement. This is not just an animation issue. I have moved the throttle through the entire range very slowly and at no point does the "LVR CLB" prompt go away!!! The FMA does annunciate "THR CLB" and then if the throttle is moved further, it annunciates "MAN THR" and then "MAN TOGA". Also, at MAN TOGA, it no longer annunciates "NAV". It only annunciates "SRS".

Hi @ghosh9691. You may want to add a bit of a deadband on each of the detents. Try subtracting 0.02 on the low values, and adding 0.02 on the high values (except idle_low and toga_high).

[Saschl]

@ghosh9691 thank you so much. As @tracernz already mentioned you’re missing some range around the detents. We’re aware that this might not be clear through the UI and are looking into improvements

[ghosh9691]

@tracernz , I will try that out tomorrow and report back here. Btw, the above was written out by the EFB throttle configuration screen. So maybe if we need a small band, then the EFB screen should add that by itself.

[ghosh9691]

After making the changes suggested by @tracernz above, and updating to build (as stated below), this is no longer an issue. I have also noticed the following in this new build:

• The FMA now correctly annunciates: MAN FLX with SRS & NAV, also MAN TOGA with SRS & NAV (was not doing so in previous build
• Correctly annunciates THR CLB and no longer has the "LVR CLB" flashing message
• A/P no longer does the happy (?) S-dance when approaching a waypoint as it was doing in previous build (a left turn followed by a right turn followed by correct turn to capture track to next waypoint)

Given the above, I am closing this bug as "RESOLVED"
