The flap position for launch is a setting of approx. +15° . With the flap against the keel, the deflection is

approximately -5° . Foot launching the glider is very similar to launching a flex-wing glider. Accelerate the

glider smoothly as you fly it off the hill.

From an aerotow dolly, a similar flap setting is advised. Adjust the cart so that the angle of attach of the

glider is not excessively high, 15° to the horizon is practical.

Flight

In flight, only the spoilerons are used for roll control. Weight shift does nothing. The control loads for the

initiation and roll-out from a turn are clearly lighter than with a flex-wing glider. The ATOS possesses high

stability around each axis. Therefore all the input movements can be gently implemented. Roll the glider

by pushing the control frame in the opposite direction until the proper bank angle is achieved, then

release the pressure and allow your body to re-center on the control frame. Smooth inputs are

advantageous.

With stronger deployment of the spoiler a slight pitch-up moment occurs, therefore you must be

particularly cautious not to fly the glider too slowly. You'll have best results by smoothly flying at

constant airspeeds. Close to minimum speed and maximum speed (90km/h - 53mph) the glider should

absolutely be flown with an airspeed indicator.

Having a good airspeed indicator and understanding

of your polar will be very important in getting the most performance from your glider.

The ATOS VR is not suitable for Aerobatics. The glider can easily be over-sped and thereby, the structure

overloaded!

Thermaling and high-speed flight

When thermaling set the flaps at 15-25° . This provides agile handling and desirable trim speed. With

large or torn up thermals a smaller flap deflection, lower bank angle, and slightly higher speed will better

average the up and down air. You'll notice that the glider trims more slowly with higher flap settings which

can influence the combination of speed, bank angle, and flap setting that you choose.

At speeds of 32 mph and above, the best glide is achieved with the 5° flap position. VNE is 53 mph - the

glider can be flown with the flap and tail cord completely loose in smooth air, in these upper speed

ranges.

With the flap rope in the full off position, there will be little or no control bar pressure and

so the requirement for an airspeed indicator. At airspeed above 45 mph, extreme turbulence can

overload any hang glider.

Landing

For landing the flaps should be pulled in to between 15 and 70° , since this gives the lowest stall speeds.

Glide path will respond to airspeed the best with full flaps - pull in to steepen the glide path but always be

careful to keep your speed up with large flap deflections. An approach speed of 30 mph is advisable.

Particularly on your first landings it is advisable to take a long final and set the flaps while still above 150

feet. Hold your hands about half way up the uprights and body at 45° . Hold a steady speed to the ground

and level out the glider until trim speed. Slowly but fully rotate the nose up. Be sure to hold the nose up

and run under and through the control frame so that the glider will settle on your shoulders. If your hands

and the control frame are in front of you when you quit running, you will not be able to support the glider's

weight at arm's length!

Possible errors:

Too fast approach in combination with large control frame excursion. Adjusting the flap deflection late

during the landing and not remaining the focused landing point ahead. Too small airspeed with a high flap
