Lockheed L-1011 Autothrust TM mode EPR problem

[Eli128gb]

Hello everyone, 

 

I have the problem that whenever I want to use the Thrustmanagement mode to climb, it shows the EPR 000 and the engines spool down. I have set everything up correctly including both PMS, have already played around with switching of probe Heat, and many more things. I would be really glad if anyone had a solution or at least knows if this is a bug or I’m missing something systemwise. 
 

kind regards Elias!

You have to fill in all the required parameters in the first 4 pages or so like BOD distance etc. Happened to me as well until I figured it out

I did that but mine still does the same as @Eli128gb says until I engage the autopilot, then it works. 
 

Side note I have my airplane set to KG in the PFB do I still need to put LBS into the PMS? I have been putting KG into it.

Did you need to engage the autopilot itself or just set a pitch mode on the panel? I found that mine would engage correctly as long as I had some pitch mode engaged. But still, it's supposed to be completely independent, isn't it?

No I had to engage the autopilot itself (move one of the paddle switches) in order for the TM function to work properly!

[Joshua Green]

Ok, definitely sounds like a bug, then.

I just checked and it doesn't matter what units I enter. TM mode gives 000 until I engage the autopilot. I have seen the same behaviour on several people's videos and streams as well. 
I wonder whether the team can confirm whether this issue has been logged.

Hi, this is gonna be a really weird ask, when this is happening to you, is the CLB Page on the PMS open when this issue is happening?

It happens regardless of which page I have open on the PMS, so yes also with the CLB page.

[IniJamir]

We have an issue logged with this occurring with the CLB page open, I'll add notes that this is occurring with other pages open as well.

This is still occurring btw please don't forget it 😭

Seeing the same here. All the PMS data is filled and yet it shows 000 and retards throttles as soon as I try to engage TM after TO. 

Until I engage AP - then, TM goes to climb EPR instead of 000.

On V1.03..
I have noticed on departure that the EPR changes in TM when you switch between PMS pages, primaily the CLB page giving a really low EPR.

@Genista So you have filled all the details (GMT, GW, FUEL & SAT) below and no EPR value shows in the PMS? 



Also - when you choose TM after takeoff does the lower window show AOA? If you are too slow AOA will ignore any EPR or speed settings. 

[Trevor]

Did you re-enter the GMT?

[Genista]

Yep to both. GMT and weight updated right before TO.

 

If I engage TM with AP off:

 

With AP ON:

[Joshua Green]

There is clearly some logical linkage in the code between the autopilot state and the autothrottle logic. 

My understanding is that the two are not mutually dependent in the real aircraft, so even if you CAN get the correct EPR value with the AP on, that shouldn't be a necessary step.
