F28 Professional

@mark thanks for your reply. Meanwhile I found the issue. It was the better bravo lights add-on. Removed it and since then everything seems to work.

@martyn like the challenge to tune the correct NDB frequency and check the reception level! Not easy yes, but that gives some charm to our F28

Just did an other flight tonight, same problem with autopilot only during initial climb and until 10000/15000ft. First when engaged PA after takeoff, nose diving and aircraft descent to -500ft/min. Just after nose up with a rate of 4000ft/min. So impossible to accelerate to 250kts. When engaging HT to try to stop climb and accelerate, aircraft refuse to nose down, still climbing and crossing 10.000 ft at the speed of 200kts. I switch off autopilot, level off, accelerate to 270tks and re-engage PA with IAS mode. At this time is becoming good with the PA until the end of flight. Without GPS, community folder empty except only using GSX and some files link to navigraph. Pitch switch and PA activation use via joystick shortcuts.

@kamow52 Look above were the white light is, on the right side you will see a small button. Press it and it will switch on-off the dom light. Very diffcult to find in the first atempt.

@papafox85 OK THX for info.

@dadgametime No doubt (qualified guess) F28 used the same INS system as Fokker F50. (licensed tech course on F50). Calibrating updating INS during flight, the system preferred at least 2 DME for triangular calculation, secondary VOR direction. Least preferred was GPS. Great to pinpoint a place on earth but not altitude. The slant range is better with DME/VOR calculation for altitude. For me - I keep the F28 as is - and wait for F70 and F100.

@piedmonitor are the VOR needles moving for you when you turn the knob on the glarshield? I´m using the bravo throttle too and the needles does not turn when I turn the knob.

@martyn Yes, my apologies, my mouse is lagging on another aircraft. My mouse just started doing this and the F28 was the plane I was flying at the time. This is going to be a "fun" one to troubleshoot. I have so many different addons.

@mark I don't have any mixture axis assigned on the Bravo profile I'm using. I also don't have any keybinds assigned. Should I assign an axis and just keep it at max?

You don't really need another mod like this. You can access the GTN750 from the sim toolbar.

Thanks for reporting this! We've spotted a bug that prevents the "GPS" progress annunciators from illuminating amber on the FO side when tested and we'll get that fixed for the next update. Mark - Just Flight

@exp131 Been on some multi leg trips lasting well over 3 hrs as well as some long single legs.
