ASK21, ASK21 Mi 1.00 Manual INTRODUCTION 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.
ASK21, ASK21 Mi 1.00 Manual COPYRIGHTS The manual, documentation, video images, software, and all the related materials are copyrighted and cannot be copied, photocopied, translated or reduced to any electronic medium or machine legible form, neither completely nor in part, without the previous written consent of AEROSOFT. THE SOFTWARE IS FURNISHED «AS IS» AND IT DOES NOT COME FURNISHED WITH ANY GUARANTEE IMPLICIT OR EXPRESS.
ASK21, ASK21 Mi 1.00 Manual 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’.
ASK21, ASK21 Mi 1.00 Manual INSTRUMENTS There is a highly realistic and rather complex set of instruments in these cockpits. If you are not used to gliders you might be surprised about the complexity of modern glider cockpits. All the instruments are described in some details. VARIOMETERS Variometers or, in short, varios are vertical speed indicators (VSI) which show change of altitude by measuring the change in air pressure (static pressure) as altitude changes.
ASK21, ASK21 Mi 1.00 Manual The Total Energy Compensated variometer provides that information "It shows the vertical speed while effects of aircraft maneuvers are eliminated. For a mechanical vane vario this is achieved by using special static pick-up nozzles which combine static pressure and pitot pressure".
ASK21, ASK21 Mi 1.00 Manual will learn that speeding up causes the sink reading on a TE vario to increase, as the glider is less efficient at higher speeds, making it even more difficult to decide whether to speed up or slow down.
ASK21, ASK21 Mi 1.00 Manual C4 COMPETITION Without a doubt the heart of this product, the C4 competition is a flight computer that is used in glider competition (but also for recreational flights). It is capable of using the loaded flightplan, your GPS-determined position and the performance of the glider to make many calculations. It is far too complex to describe them here and we are happy to have permission of the manufacturer (Franz Pöschl GmbH) to include the actual manual.
ASK21, ASK21 Mi 1.00 Manual TRANSPONDER The ASK21 Mi is equipped with a Mode S transponder unit making the ASK21 Mi better suitable to operate in controlled airspace. It provides A and C (including altitude) modes. It is toggled on with the OFF / SBY / ON (A mode) / ALT (C mode) switch and you set the digits by pressing the large knob to select the digit and then turning to change the digit.
ASK21, ASK21 Mi 1.00 Manual STATIC PORT SWITCH There are two static ports (to measure static pressure) on the AKS 21 Mi. One total energy compensated (TE) mounted on the Vertical stabilizer and the others are little holes in the fuselage (Stat). The Static Port switches the source of the variometers between these ports and is marked with glider and motor operation. When you use the engine you need to select the static port in the fuselage to get a correct reading of the variometers and prevent failures.
ASK21, ASK21 Mi 1.00 Manual WINCHX! AND OTHER ADDON PROGRAMS FOR GLIDERS There was one serious problem when we started with the first glider project. Motorized gliders cannot be towed into the air. FSX simply will not start this process when the glider has an engine. So we had great gliders but no way to launch them. With the release of WinchX! this problem was solved. Though highly realistic the product is not overly complex to use. It is also content of the ASK21 package.
ASK21, ASK21 Mi 1.00 Manual FSX SETTINGS This product needs a few tweaks to the FSX settings to allow you full control over the glider. SOUND We advise you to move all sound sliders to the maximum setting. REALISM We strongly advise the flight model settings to be set to fully realistic to get the best flight model. Of course flying the glider without any form of rudder (and autorudder activated) is not very realistic. A smooth moving, softer stick will be most realistic and most easy to use.
ASK21, ASK21 Mi 1.00 Manual SPOILERS In an aircraft that has no engine and is designed to glide as efficiently as possible it can be amazingly hard to land as the aircraft will tend to glide a long way in the ground effect. Thus the use of the spoiler is very important and you will need smooth control over it. If your control hardware has an additional slider (like for example the Saitek X52) we strongly advise you to assign that to the spoilers so you can control the spoilers in small steps.
ASK21, ASK21 Mi 1.00 Manual APPENDIX A The manuals we provided are for the ASK21 Mi and there are some minor differences between that version and the pure glider version.
