Please note that due to a bug in Prepar3D V.2 a motorized take-off from the ground is not possible without any wind
(the default Constellation shows the same problem!) Lockheed promised us to check this out. For now just add at least
one knot of headwind.

INTROD UCTI O N

Most people who have not been in a modern glider think that they glide from thermal to thermal in total silence. They
can and they do, but they are also capable of the most amazing aerobatics and high speed high G maneuvers. Often the
roar of the air flowing over the canopy drowns out the sound of the variometer and the screams of the passenger. They
are often flown closer to the ground than most other aircraft, certainly when they are flown using the wind flow rising
over mountain slopes. Even if you look at simple performance you see that modern gliders outperform many serious
motorized aircraft. Name one general aviation aircraft with a range of 3.009 km, a speed of 306 kmh, and a ceiling of
15,460 meters. And although these are world records for gliders, even the actual performance of standard gliders is
amazing.

The Schleicher ASK21 is one of the best known gliders as it is used in many glider schools. It’s not a hard glider to fly

(that’s what makes it a good instruction aircraft) and considered very safe. It’s so safe that to practice spins you will
need to install a ‘spin kit’. The ASK21 has a conventional layout with controls for both seats, a T-tail and a mid-set thick

wing.

The FSX version was made with great care by Joachim Schweigler who knows this aircraft very well. Perhaps the most
special part of the product is the flight model that is at the absolute limits of what FSX can handle. It is extremely
accurate.

CONTAC T S U P P O R T

Support for this product is offered by Aerosoft. We prefer to have a support forum for the simple reason that it is fast
and efficient because customers help customers when we are sleeping.

Aerosoft forums: http://forum.aerosoft-shop.com

We feel strongly about support. Buying one of our products gives you the right to waste our time with questions you
feel might be silly. They are not.

SETUP OF T H E M A NU AL

As with previous projects we divided this manual into separate sections. This section is about the aircraft in FSX and
about some of the special features of the project. The other sections are actual real life manuals of the aircraft and the
instrumentation. This project is so accurate and realistic that we feel confident giving you the actual manuals. The
bonus for you, the customer, is added realism. What can be more realistic than the manual used by the real pilots?

You will find all the manuals in the same directory (FSXMainFolder\Aerosoft\ASK21\) with these names:

 Manual.pdf What you are reading now
 219FD komplett.pdf Flight manual for the ASK21 Mi (German)
 219FE komplett.pdf Flight manual for the ASK21 Mi (English)
 EN_C4-V4.06.pdf Manual for C4 Competition (English)
 DE_C4-V4.06.pdf Manual for C4 Competition (German)
 EN_WinchXHelp Manual for WinchX! (English)
 DE_WinchXHelp Manual for WinchX! (German)

Please note that the Flight manuals only cover the motorized version but are to a large degree suitable for the pure
glider versions. Appendix A will cover the few differences.

The copyrights for all manuals expect this section remains with the companies (and individuals) who created the
products.

MODELS

There are two models of the ASK21 included in this project. The standard glider and the ASK21 Mi that has a Diamond
IAE 50R-AA engine delivering 37.3 kW. This is enough to allow the ASK21 Mi to take off eliminating the need for a tow
aircraft and extending the cross country capabilities. However that does not mean this is a motor glider. The ASK21 Mi
is classed as a ‘motorized glider’.

FLIGHT MOD E L

One of the highlights of this project is the flight model without a doubt. It is highly researched and tested by several
glider pilots with many hours on that type. Where FSX caused problems modules were used to circumvent the
limitations. For example the standard additive trim of FSX (you can move he stick fully back and then ADD more
deflection with trim) is not realistic and is replaced with a system that actually models the spring loaded trim system of
the ASK21. Without this it would simply not be possible to do the full aerobatics program the ASK21 is capable off.

If you know the ASK21 you will find our model extremely close to the real flight experience!

AEROBATI C S

While being designed as a trainer the ASK21 is a very capable aircraft that is used for aerobatics (class A Aerobatic) and
cross-country flights. It is approved for these maneuvers:

 inverted flying
 slow rolls
 loops
 spins
 stall turns
 Split ‘S’
 Immelmann turn
 steep climbing turn
 Chandelle
 Lazy Eight

The ASK21 Mi is a lot less aerobatic (it is classed as a utility aircraft after all) due to the lower load factors and it is
certified for:

 spins
 steep climbing turn
 Lazy Eight
 loop upward.
