All Circuit Breakers are in? Reset all Failures? With Avionics on, a preselected HDG Mode should stay on. I think, you have a mismatch in your Keyboard or Joystick Settings. I use the Bravo Quadrant and the AP Command for the Push Button is "Servos Toggle". It looks like there is a conflict with the Settings. Start with a complete new Joystick Profile, assign it to the Moo and reset the Settings in this Profile for Joystick and Keyboard to Default. It's always a good Idea, to leave the Default XP Joystick Profile untouched or only assigned with a few Basic Settings for the Flight Controls and copy them to a new Profile. It's a bunch of work but you will have a clean Profile for any Plane and a changing for one Plane did not effect others.

And what Mode are you trying to fly with the AP? With the GPS Radio Stack (I don't use the OEM Version): Set the Heading Bug to the Direction you are flying, hit the HDG Button at the AP Mode Panel (plus ALT) and then switch on the AP. What happened now? What happened when you moving the Heading Bug to a new Direction? You should be now in Heading and Altitude Mode. If you want to follow a Flight Plan set or loaded into the Garmin, hit the NAV Button. Following the Magenta Line with GPS. Set CDI in the Garmin to GPS and and switch GPS on with the Switch in Front of you.

Yesterday the 5-Blade Version won't Feather for me. Today it does. When changing the Versions, the Sim sometimes needs a Restart.

And did it Feather on Emergency Stop? Mine did not. Only the 4-Blade Version did.

Looks like the 5-Blade Version has a Bug. It never Feathered. Not on normal Shutdown and not with the Emergency Stop.

As rosseloh said, you can still choose the Payload from the Standard Menu when you choose your Plane for the Flight. Click on the Customize Button below the Airplanes Icon. That's the Way for many X-Plane Airplanes. The MU-2's Preference is for a Quick and Dirty Fuel Fill up at the Moment.

Payload is Fuel only at the Moment. No PAX or Baggage. You can fill the Outer, Inner and Main Tank from the Pref Menu. But only Full. For other Fuel Loads than Full, you have to use the Customize Function were you choose your Plane. For Development Status, tkyler has just updated the Status:

No, Cold and Dark is unfeathered. If the Props are in the feathered Position, you have to unfeather them before starting the Engine. They will be locked in the feathered Position otherwise. That's the Mechanic of this Engines. Lock and Unlock Position is described in the Manual. If the Prop is feathered in Cold and Dark, place the power lever in REVERSE and hold the unfeather switch until the blades reach the lock position. Beta Lights will lit then. After Engine Start, Props must be set "Off the Locks". Condition Lever full forward and Throttle in Reverse. Or you will have no or less Power. If you want to Shutdown the Engines with Props in Feathered Position, Shutdown the Engine and put the Throttle in Reverse before RPM drops below 60%. Did not always work in the SIM. Reloading the Plane or switching to a new Airport resets this Setting. I think that's done for easier Handling of this Plane for those, who are not so familiar with the Procedures. They may wonder why they have no Power after starting the Engines like a PT6 Turbo Prop.

I did not use replay very often but did the Flap Animation work with other Planes?

So your Throttle is working in general but when throttling down, you did not reach the Beta Zone?. Did you assign a Button or Key for the Lift Off Function? A older Video from me for the Settings. Don't forget to change the Throttle Response Curve as shown above.

So maybe a Bug or not implemented.

It depends if the GPS and the Airport has WAAS Support. And the Aircraft too. Don't know, if the 530 in the Moo has this Support. There was a Discussion about the WAAS Support in XP12 at the Xorg Forum. So maybe, the Moo can't do this kind of high Precision GPS Approach. https://forums.x-plane.org/forums/topic/286314-no-waas-rnav-approaches-in-xp12/

Ah, Hand flying the Approach. That did work too, just did it on my Home Airport, EDDG, RWY 25. The Moo with the Classic Six Pack Cockpit. NAV1 is set to the ILS/LOC Freq for RWY 25. RNAV/GPS Approach (RNV25 GPS, OSNAD IAF) is loaded into the Garmin 530. CDI set to VLOC. OBS Course on the HSI is set for the RWY (250). No Autopilot active. Flying the Approach by Hand. As soon as the Localizer ID is shown in the Garmin, the Localizer Indicator or Course Deviation Indicator becomes active and shows the Deviation to the Runway. When you are in Range for the Glideslope, the Glideslope Deviation Indicator becomes active in both Instruments, the HSI and the Attitude Director Indicator. The Vertical Path is shown with the small red Bars on the right Side of both Instruments. Now you can follow the Glideslope manually. I think you know, when flying a RNAV/GPS Approach with active Autopilot, there is no Glideslope following. Only Heading.

It does but it depends on your Settings. I'm not a Pilot so some steps may be not in the correct way. When following a Flight Plane (loaded and active in the Garmin), my AP is set to ALT, HDG and the GPS/HDG Switch is set to GPS. CDI in the Garmin is also set to GPS. The Plane is now following the magenta Line with GPS Support. When in Range, Localizer/ILS Frequency at the arrival Airport is set on NAV1. You know your Arrival Runway and load the RNAV/GPS approach in the Garmin. Close enough to the Airport, you activate the approach. The Plane is now following the approach Procedure. If you see the Localizer ID in the Garmin, switch the CDI from GPS to VNAV. You will now have Localizer and Glide Path Support but the Plane is not following the Glide Slope until you hit APR on the AP. You have to decent at your own. And the ILS System at the Airport must support Glide Path.

Did you mean this?
