F28 Professional

Thank you to the team ! ;)

@derek yes, thank you very much in this case. Thanks for guidance 👍

Hi all,

Just to clarify a few things that have been mentioned in this thread.

The VOR "spirals" issues isn't something we have ever been able to replicate, but I have personally seen a very small number of users reporting similar issues. As mentioned above, making sure the Working Title GNS530 is fully up to date should solve the issue. As much of a chore as it can be to keep everything up to date, we would recommend always keeping any GPS mods fully up to date to minimise any chances of issues appearing. It's probably the number one cause of autopilot issues we get through our support channels across multiple aircraft.

The autopilot roll oscillations are a known issue when no GPS is selected (weather radar visible). We do have a solution for this that is currently in testing, but we need some time to ensure the fix works across all possible scenarios. As soon as we are confident in the fix, we will push a new update out for the F28 Professional. The difficulty we face with the F28 (and our PA28 range) is when the Working Title GNS530 is selected, it tries to take control of and override all of our autopilot code, so we have to effectively code the aircraft systems and flight model so that it works with multiple autopilot systems, which gets very complicated very quickly! One last-minute improvement to the Autopilot behavior with the Working Title GNS530 selected has likely caused this knock-on effect with the basic Autopilot functions which went unnoticed ahead of the v0.1.2 release. As a short-term solution, you shouldn't have any roll oscillations when the Working Title GNS530 is selected on the EFB.

If anyone is experiencing any issues with State Saving in v0.1.2, if you can contact Just Flight support we should be able to provide a fix for that: https://www.justflight.com/support

@scaflight I just replied in your topic. Hope that fixes the issues for you as well. :)

@mark It sounds good to me! Many Thanks ;)

@mark Oh yes! Indeed now it makes sense. The barber pole is the issue, not the speed, my bad!
And this also answers my question about fuel flow -> I was actually accelerating to mach 0.8 instead of the usual 0.75 so that makes sense now..

Concerning the altitude, I was wondering if for long flights like this one (2h+) you could climb above 30k to save more fuel. It makes sense not to climb farther for short hops, but for long flights...?

Thank you for taking note of this bug and I hope it gets fixed very soon ;)

@mark Will do thank you - I had seen the 0.1g spec but it "felt" a lot more effective than that. Given how slippery the little Fokker is it's nice being able to chuck the anchors out but I'll take the realistic version always.

Please do check the outside view - to me it was very noticeable against clouds - I was in a 4000 at the time.

My pax must have had bulletproof bladders because I didn't get any toilet visits but I did see one cabin call - for me, it all adds heaps to the immersion.

Keep up the great work on this fantastic plane - remains my #1 choice!

Hi,
In simple words yes, it is possible to start the engines with both fuel booster pumps off.

@voice-of-reason no worries, I’m sure patience will be rewarded. Apart from some little bugs I can’t imagine the Fokker getting much better than it already is so I’m curious what you’re bringing in this update.

@celti thanks turns out i just needed to reboot msfs and it was fine

@martyn
It works again, indeed.
Many thanks :thumbs_up:

@mark Thank you so much for listening to the community and the hard work!! I can't wait for the update.

@papafox85 ok thanks

That is correct behavior and it is simulating the bleed air auto shut-off system which automatically shuts off the air conditioning MAIN valves when additional air is required by the engines in order to achieve the desired thrust level.

A table showing the valve states with various RPM settings can be found on page 35 of the F28 Professional Operations Manual and we go on to explain a little about this system near the end of the "Bleed Air Supply & Air Conditioning" video that we posted a few months back: https://youtu.be/lVewFdk3y5I?t=248
