Just in case you are interested. This is a pilot manual for the DG1000 with an US registration so you also see the speeds in kts.

See page 2.4 for the various speeds.

When ridge flying at least when approaching the ridge for the first time, it is good practice to stay maybe 30 to 40 km/h above stall speed (ca 120 to 140 km/h). But it also depends how windy it is and if you expect it turbulence. Once you made a few passes always turning away from the ridge against the wind you can slow down so you climb better.

So there is no one speed for ridge flying. One always varies it depending on the situation.

Vario sound stopped working. Anyone with the same problem?

Thanks, I most certainly will read it. And that’s good advice about ridge flying, it’s all too easy to get caught in a downdraft so some extra speed is essential.

And while you are at it :wink:

This is the “famous” mountain flying safety manual by the French Gliding Center in St Aubain (in English, hope the link copied correctly )

Nicely illustrated and plenty of good hints about gliding in the mountains including ridge, thermal and wave soaring.

Edit. Now in English

Nice 
 my schoolboy french is a little rusty but I’ll give it a go
(google translate is my friend :wink:)

Sorry. My mistake. I edited the link. Now in English.

Got it thanks :smiley: and probably just as well too, le chat sat on the mat is probably about as far as I got :grin: :wink:

As a RL glider pilot you (and others, also those who want to know how it is in RL) may be interested in bug report I filed about incorrect position of thermals in relation to Cu clouds (we glider pilots mostly use clouds to determine where good thermal can be found) Incorrect spatial relations between thermals and Cu clouds makes realisic glider flights impossible

No matter how realistically modelled will official gliders be if the element in which they move behaves fundamentally incorrectly, so please support fixing thermals.

I thought there already was a thread for that. You don’t want to split the voting or it will never get fixed.

Did you watch the last dev Q&A? - Sebastian explicitly asked for bug reports in relation to current thermal model. There is also a generic ‘improve thermals realism’ wishlist item, but in this bug report I concentrate on factual, specific bugs in thermal model in relation to clouds. We can upvote wishlist all day, but sadly that won’t make specific bugs fixed.

EPPRGlider81,

I wonder what a Slip indicator would show when flying these default gliders. We have odd yaw string physics/modelling, I miss not having a slip indicator. If one was present, it might not be useful with the current simulator physics and may highlight the current flight modelling problems. I may be a little cynical, there may be reason a slip indicator was left out!

Hopefully a correctly working little slip indicator will be incorporated soon with decent yaw string modelling which ultimately will give me confidence in the aerodynamic modelling of the two Asobo gliders.

Otherwise, I have enjoyed my little bit of soaring that I have ‘tried’ in the simulator with this glider, even though it’s arcadey at the moment for real glider pilots.

Charles.

Yeah the whole giding concept seems a little rushed and unfinished but I suppose deadlines were tight for much of the anniversary content. 
 I really don’t think we will have to wait until SU12 for many improvements so keep checking content manager and remember that a lot of the weather data gets streamed and so should be adaptable server side.

Very interesting! :+1:
Thank you very much for sharing the Link!

I filed a bug report about not enough adverse yaw - Both official gliders should have stronger adverse yaw requiring use of rudder for turning please support it, as bad reflexes of not using rudder for turinig in gliders trained in the sim may cause RL deaths with unexpected sping during final turn when in stressful situation people return to the first reflexes.

I just uploaded a little mod for this glider on flightsim.to (https://flightsim.to/file/44490/dg-1001e-mod).
Real life glider pilots, please comment on the adjustments I made! If you want to fiddle by yourself with the numbers, you could have a look into th flight_model.cfg - search for “was” - so you will easily find where I adjusted values.

When activating dev mode in MSFS you can visualize a lot of sim variables, airflow and forces acting on the wings. There I found that the spoilers seem to be not really modelled as surfaces for the CFD aerodynamic computations. Instead of disturbing the airflow just over their own length there are changes in the aerodynamic forces over the whole wing span which shouldn’t be.

For adverse yaw, there are 2 parameters in the flight_model.cfg which I don’t really understand. So my changes were just guesswork.

As for aerobatics (yesterday I tried some loops, rolls, stall turn - didn’t succeed), the rudder and aileron authority seems low, but it may be just so in reality.

Just a heads up - in the first version, the SimObjects folder was missing in the zip file, sorry for that. Now it’s complete, just download again, please.

Thanks for the great mod.
I love it.
However I thought the spoiler effect was still lacking.

With fully deployed spoilers you can descend with 3-4 m/s and an airspeed of 120 km/h which seems OK to me.

It seems that dynamic stall properties are not properly modeled.
No matter what I try I cannot generate accelerated stall.
One very clear indication of improper model is the impossiblity to do “Half positive flick roll from normal to inverted flight” maneuver as described in DG-1001 flight manual:

120 – 140 km/h (65 – 76 kts.).
Prior to inducing the flick roll, place the nose a little below the horizon.
Induce the half roll with full stick backwards and full rudder only.
After the rotation starts ease the stick to neutral to avoid too large an angle of attack and unnecessary loss of speed.

The wing in the direction of rudder should experience dynamic stall this generate huge rolling force that is necessary for this maneuver - note that no ailerons are used i nthis maneuver to roll the glider upside down!
This is currently impossible with modeled glider as no necessary for the maneuver stall condition is generated on the wing!

Correctly modeling accelerated stall is crucial in proper stall training, as many RL deaths were caused when people when recovering glider from unexpected spinn pulled the controll stick too much causing accelerated stall and thus entering another spin (typically in opposite direction to the previous) - this way loosing too much height and fatally crasing. This must be modelled to train proper recovery procedures!

While I agree with you in the sense that I want MSFS to have maximum realism and realistic flight dynamics, is it really meant to be or planned to be a flight training tool for real world pilots to this degree?

I could understand your reaction if this was $1 million glider simulator tool, but a $60 game?
