I have experienced this problem at Aboyne in Scotland, in my case I appeared to be hitting an invisible object. If you have a third-party airport scenery, try disabling it for your next attempt. I have a third-party scenery installed at Aboyne. The Cessna would be better replaced with a Piper Pawnee. It would be nice if a basic model of the Pawnee could be incorporated specifically for aerotows, just as we have the choice between three types of winch we could have a choice of three tow planes. I was wondering if a wing-tip was hitting some tall invisible grass and triggering a failed launch?
I did my real Blanik flight many years ago (not solo) but I can tell you that I expect to not stress tow aircraft and lift off with glider little bit early than tow aircraft. It is common practise and normal due glider performance. In this case tow aircraft can have some power enough of course. You need be little careful to not do any crash.
Update … in addition to the aforementioned tow plane acceleration problem, I noticed that the starting position penalizes the take-off run, In fact the tow plane is already almost halfway down the runway.
So, slow + half runway = disaster
I also found that the starting runway is also wrong because the take-offs are made on asphalt.
this is simply sim, your glider is set on rwy as start point is defined so tow airplane is penalised here.
What is funny to me is front pilot’s hat through canopy on DG heh How it can be finished for SU release…
+1 cant take off with tow aircraft. Both in the tutorial flight and in any airport. The tow aircraft is too slow and goes out of the runway to left on take of roll then stops.
ok well weird,
yesterday I was not able to take off with tow aircraft. Today I wanted to give another try. It was ok. The plane speed up, keep the runway center and took off with me.
Do you have the same issue if you follow the OP’s steps to reproduce it?
YES
Provide extra information to complete the original description of the issue:
Spawing the glider at any airport: After waggling the rudder, the tow plane moves forward a few feet, then stops for no apparent reason. Have tried this with both gliders, at least 10 times now.
If relevant, provide additional screenshots/video:
While I haven’t ever experienced this issue, nor have i exhaustively scanned all the threads, but there’s a couple of commonly confirmed situations that cause take-off issues. It might help you get community feedback if you’re here to report the same kind of thing be a little more explicit about what is or is not going on, or find a way to get up and flying.
If you have 3rd party scenery files in your Community folder, that has stopped the spawning in of the wing runner and caused rudder waggling to not cause the towplane to initiate the takeoff. If you can’t see the wing runner, this is likely your issue. Disable all content and restart the sim to prove this is the cause for you. If so, get an update to the scenery to address this (ie it’s not the glider or the sim).
If you take off on a short runway, the towplane will stop part way down the runway (as it’s unsafe to take off). Try a longer asphalt runway, try a winch launch, and see if those things help you take off or if there’s some other fundamental reason the takeoff won’t work.
If you experience one of these, try to describe what you were doing (including the airport ICAO code so someone else can test/confirm) and what the plane and glider both did.
So, finally I fixed the problem…
I made the asphalt runway/taxyway active (actually it is on this runway that you take off at LILC), setting the starting point at the correct point and the poor Cessna takes off before having finished the runway…
More than a bug, this is a problem for all scenes with a short runway, I repeat that the basic problem is the choice of an inadequate towplane because with the Black Box Simulations Cessna L-19, with the default scenario and glider loaded with ballast, takes off great.
I hope Asobo, or whoever, gets the message and fixes it officially.
