Piston & Turbine Dukes

@Randolf said in RNAV LVARs: when the plane is stationary on the ground, the DME display when switched to RNAV mode, starts counting wildly upwards till it reaches 999.9 and stays there I saw this for the first time today and immediately found the problem. It was due to the interpolation I added to enable autopilot tracking from the RNAV system. Believe it or not, the DME information update interval from the simulator is so slow that it cannot be used to accurately drive an autopilot! I suspect that code has been unchanged since the 1980's.

Hi All, I added a quick solution to this in all four of my aircraft that have the tablet installed now. There will be an persistent option on the tablet titled "VR Tablet Static Position", which will lock the tablet in a position much further away from the camera, and obscuring as little of the panel as possible. I my VR users will find this to be a comfortable solution!

@Black-Square said in START/IGN Fuse always blowing: hardware bindings are causing the starters to continue running behind the scenes Good call. Using SPAD once I unbound the key switches works like a top. Thanks for the hint!!

Thanks, I understand better. I no longer have any problems starting the engines.

The only other solution I can suggest is to use the flashlight (Alt-L) temporarily as needed. Perhaps change the keybinding to something that's quicker/easier to use, or a spare button on a controller. May cause night-vision blindness; use with caution! (There are always those incredible flashlight-colour-changing add-ons which you can buy in the Marketplace. Surely great value!)

From memory (standard disclaimers: only for simulator use, I won't be liable, I'm not a flight instructor, etc.), the Cessna 172S POH says to lean for ground operations by setting 1200 RPM, then leaning for max RPM. In practice, you can lean somewhat further, and at some point you know from experience about how far you need to pull the mixture knob out.

@Raller said in COWL flaps when loading the plane on the runway: Mississippi, 2 Missisippi, 3 Missisippi That is indeed exactly how Duke operators learn how to manage their cowl flaps. The real reciprocating engine Duke owner who contributed to this project recently said to me that he plans on creating an aftermarket solution for Dukes with a small digital indicator for the cowl flaps position.

@Nicotine70 I've sorted the issue now. The fix? Absolutely nothing, it randomly decided to work for no apparent reason at all. It's definitely not a binding issue as I have nothing bound to any AP controls (control surfaces, trim and power management only).

Strange enough, moving the A2A Comanche out of community resolved the problem.

@lilycrose - I’ve been noticing the same thing. While I think I’m usually pretty kind to the engines, there was one flight where my CHT hit the redline a few times, and I’m surprised that both of my Duke’s engines have remained at 100% after all of my flights so far with no repairs done. When I was primarily flying the Bonanza it definitely showed a little wear over time with similar treatment. It has had me starting to wonder if there’s something not quite working here.

@Black-Square - Thanks. Sure enough, it was a failure and I misread the manual.

Just finished that flight, SCCI-SAWH. I changed from PMS750 to GNS530 and 430. I didn't use the GPS for navigation, but only VLOC mode. No problems at all. Everything worked as expected. Maybe i will try it again with 530 but using the GPS for navigation.

Thank you very much, that's what I understood.

Ok. then I made a mistake in my thinking. I was of the opinion that the friction lock acts on the trim. Thanks for the quick answer. Michael

@LondonSimmer looking at the files, I don't think the final prop heat amp value is actually saved into a convenient variable, but this is a simplified expression that is used to calculate value on the prop amp meter on the panel: (A:PROP DEICE SWITCH:1, bool) 17.5 * (A:CIRCUIT ON:10, bool) * (A:PROP DEICE SWITCH:1, bool) 18.0 * (A:CIRCUIT ON:11, bool) * + (A:ELECTRICAL MAIN BUS VOLTAGE:1, Volts) 12 > * The actual expression is much longer, and introduces effects like the needle wobble, but this should be just the plain numbers, if I got it right. Seems to work for me.
