Plane takes-off by itself

Just wondering if anyone else has encountered this. All my autopilot settings are switched off. I taxi to the runway, throttle up, release the brakes and concentrate on holding a steady line. Then the plane takes off all by itself. I can let go of the joystick and it continues to ascend unhindered. If I restart the flight and try again then 9 times out of 10 I have full control and can take off as normal. This auto-take-off is happening with the DV20, C152 and C172 and happens irrespective of the weather conditions.

It’s a pain because I start always from cold and dark and taxi. And because I manually set weather presets (abandoned live weather after SU7: severe weather transitions, airport weather bubbles, uninspiring repetitive clouds and near permanent volcanic conditions at Dublin), it takes me around 20mins to get everything set-up and start take-off only to have to ESC and start all over again.

Any advice is appreciated.

Thanks for the very quick reply. Yeah I have checked that from the toolbar and it’s always switched off.

What would you expect it to do other than this?

Keep the Parking Brake on until you are ready to takeoff.

Thanks, will do. So checking before and seeing it is off and then checking again when the plane is auto-taking off and seeing it is on: will that help me solve the issue?

With autopilot assists off, I would expect that I decide when to take-off, not for the plane to take off of its own accord before I pull back on the joystick.

Pulling back on the joystick only raises the elevator.
The joystick has nothing to do with take off.

Anyway, it is evident that I do not understand the problem.

Thanks again. I hear what you are saying. However when it auto takes off it generally does so very soon I’m rarely travelling fast, plus I can take my hand off the joystick and it continues to ascend by itself, it’s flying by itself.

When I restart, 9 times out of 10 the problem is gone and the plane takes-off as expected when I pull back, for example at 55knts in the 152. If I leave go of the joystick now the plane, as I would expect, dips forward and will start to fall.

This auto-take-off started around 3 months ago.

Yeah I checked in the main menu and from the ingame toolbar and everytime I check the AP is off. I agree that somehow the sim isn’t registering that this is off. Why it’s not registering that it is off is a mystery.

I’ve checked all the Assistance Options under piloting, everything is off, as is AI piloting in cursor mode under user experience. I’ll keep digging, I’ll let you know if I figure out the root cause.

Sorry, I now see you are referring to ā€œTakeoffā€ as getting airborne.

I read that if an airplane is configured correctly for takeoff, that
it will automatically go airborne (rotate) by itself before reaching the end of the runway.

This requires that the joystick is calibrated correctly and that the plane is trimmed correctly for takeoff.
It is not flying by itself.
It is doing what an airplane is designed to do, fly.

None of my planes dip when I release the joystick. They continue whatever they were doing.

I would check your controls.

Try to push your yoke/stick/whatever forward during the takeoff roll (on tricycle aircraft, on taildragger you should pull it back instead). Does this delay your takeoff? Can you control the moment it takes off by returning the controller to neutral? If yes, then you are in command of the airplane and the reason it has been taking off by itself is because the greater airspeed is causing more lift and hence the aircraft will want to go up.

Thanks Pantszer. No pushing forward doesn’t prevent the auto take off. I’ve checked some more on line and there are others who have encountered similar behaviour on AVSIM there, seemingly it is even more prevalent an issue in DEV MODE.

For now I reset my Assistance Options to True to Life, saved, then turned off the items I don’t use, generally ATC and checklists, and saved again. I just tried a test flight in the C172, I doublechecked in the tool bar to ensure all flight assitance settings were off. This first flight worked, I powered down the runway, waiting waiting waiting and rotated very very late, the Cessna took off smoothly.

I’ll report back here after my next few flights if I continue to retain control of my take-offs. Fingers crossed.

I could be talking complete dog’s dirt here as I’m not a real pilot, but as I understand it the shape of an airplane’s wings are designed so that the air pressure (if that’s the right word) on the underside of the wing is greater than that on the upper side of the wing. This generates lift which, as the word suggests, lifts the aircraft up. I’m guessing that if the aircraft is going fast enough to generate that positive underside pressure under the wings, it will naturally lift up into the air.

Like I said, I’m not a real pilot, but I am an ā€œarmchair expertā€, so I must be right. :rofl:

:slightly_smiling_face: I know what you’re saying. But for over a year since I first powered up the sim the auto-take-off never happened never, irrespective of how slow or fast I was travelling. In the last three months or so it happens more often than not on my first attempt (and never at high speeds), but then on my restart, 9 times out of 10, I control the take-off, same general conditions.

It first happened when I started flying the DV20 and I thought it might have been specific to it. But it is now happening with the 152 and 172. Hopefully resetting and saving my settings as detailed above will prove positive :crossed_fingers:

Is your flight model set to modern?

In that case it might be configuration corruption as such seems to be going around as of late. If the issue persists, then in addition you could try:

  1. Default your settings, and go manually delete MSFS locally stored settings (Steam: ā€œC:\Program Files (x86)\Steam\userdata\Steam_userID#\1250410ā€ — MS Store: ā€œC:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\SystemAppDataā€) and then try to set them again.
  2. In addition to above, delete your settings in the cloud (https://flightsimulator.zendesk.com/hc/en-us/articles/4409228619538) then set them again.

A video or screenshots (of the middle and lower console during takeoff ) m8 help to understand what is causing your ā€œproblemā€

Apologies Pantzer. This worked. It makes me think that something recently changed in the sim because for 18 months I never had this ā€˜issue’, same settings in sim. It only started happening 2 or 3 months ago.
