Flawed engine simulation

Last year many improvements were made to the general aerodynamics in the sim, taking the sim to new heights. While this is very good, the engine simulation has been neglected for a long time now. Especially piston and turboprops are flawed causing me huge frustrations.

Pistons:

  • Sluggish and slow engine response on many occasions (and change of RPM, both in the air and on the ground)
  • Lack of prop drag (or enough prop drag)
  • When leaning the engine aggressively, EGT should rise rapidly. Not the case in the default C172. Barely rises at all, and very slow
  • No rough engine when leaning too much making it impossible to lean by engine sound

For constant speed propellers:

  • with the engine off, moving the prop lever from feather to max rpm causes the prop to change pitch (move to fine pitch). Same the other way around. This should not be possible with the engine off and no oil pressure

Turboprops:

  • lack of prop drag (or enough prop drag)
  • beta range still not working as it should
  • slow torque response
  • weird engine indications when moving in and out of beta
  • moving in and out of beta is extremely slow (before something happens)
  • currently not possible to assign beta range and reverse to the power lever (like you can in X-plane)
  • we also need to be able to assign a button to press to be able to go into beta and reverse to avoid inadvertently entering beta or reverse in-flight

Many of these issues are long standing issues that have been there since the initial release of MSFS. There have been many great updates regarding flight dynamics and most recently, to avionics. Now moving forward I think it’s time to start focusing on the engine simulation. That’s just as important as the flight dynamics and avionics.

You certainly can do this, I have this set up on my Velocity one Flight Yoke.

How? Am I missing something?

Set a binding for Toggle Throttle Reverse Thrust. Once set, you pull your physical throttle to full back/idle, press the button/key for the toggle, then advance your physical throttle forward. The in-sim throttle then moves back into beta/reverse. It’s not ideal as far as realism, but it’s a good workaround.

Locate the assignment functions for Throttle X Decrease and Throttle X Cut – the X will be equal to the engine number on the aircraft.

Set your throttle levers to the 0 position – just above the final click/detent position.

When you find Throttle X Cut, click inside the assignment box to reveal the assignment editor.

Then, click the START SCANNING box, and when prompted, move the throttle lever into the detent zone and then back to 0 again. A button number will appear. Set the Action Type to ON RELEASE, and then click VALIDATE.
