Hello, Unless the Tristar has a different design, the EPR normally compares exhaust and intake total pressure, not ambiant pressure, just like a pitot probe. That means that this intake total pressure will be higher, at speed. You will observe values around 0.90 EPR during idle descent on modern turbofans such as the A320. Edit: That does look like a typical total pressure probe on the Tristar's intake: Uploading Attachment...

Hello. Currently descending thru FL300 with throttles at idle in MACH hold. Surprised to see that EPR is still 1.1. In a turbofan engine shouldn't the value be around 0.8-0.9 at idle since the engine are causing more drag than thrust ?

Seems to be working if you activate the RADIO pushbuttons on the lower right side of overhead panel !

Thanks guys ! Just tried and I confirm it works ! Appreciate the continuous support!

Same. Opened a thread in suggestions to ask if we could have all 3 filled with our flight plan during import.

Hello, Right now the PFB only seem to import waypoints into INS1. Could it send the flight plan to all 3 INS ?

Appreciate the support guys. Cheers and thanks for bringing this aircraft to the sim.

Was just hoping to find documentation that proves this, as it is quite a surprising design choice. Anyways. Thanks for the help ! Btw your document above states that after liftoff, PMS should switch to CLB page. I don't believe our tristar does that in the sim yet.

Hello all, Could you create a FAQ page to list the keybinds that works on the Tristar? Fir example I am unable to find which one works for AP disconnection. I also understand that the spoiler arm bind works differently from other aircraft. Would be nice to have a FAQ clarifying all that. Thanks !

As the title says - those switches don't seem to work at all.

Much clearer thanks. But it still doesn't indicate that engagement CWS or CMD is a requirement for it to work ! VNAV/IAS/MACH all work in conjunction with FD, regardless if CWS or CMD is engaged. Or to rephrase. PMS can feed FD with VNAV pitch commands. Even without CWS or CMD engage. Why would TM needs it ? (not trying to be pedantic, I just have never seen that design before and that makes me curious)

Hello all, I am having trouble with the cabin annoucements. Sometimes I will hear one or the other but it seems a bit random. What are the triggers for all the FA annoucements, to make sure I hear them all ?

Thank you very much for sharing. However that document does not explicitly say that TM (as you claim) would not work unless CWS/CMD is engaged; instead it just gives you the normal procedure to get the full engagement of PMS VNAV functions. Which, obviously, needs CMD on since those functions need pitch slaving too. Not exactly the same thing! Since AoA mode is able to command your throttles without any AP mode engaged, I am really curious why, from a systems perspective, TM would need CWS or CMD. In every other aircraft I know, including old designs like our tristar (I have DC9 and Concorde in mind), they live separately. Pitch/Yaw(YD)/Roll autopilot actuators can be engaged or not (on those other aircraft) but it won't affect what the A/T is doing because is it a different set of wiring, power supply etc.

Hello. With a fully configured PMS and all that; If I press TM mode but autopilot is OFF, it will command 000 EPR and retard the throttles. Is it by design/ on purpose ?

same here, in 1.0.2. ILS or LOC will not engage. Not flying in VR.
