Thermaling: flap deflection approx. 15°
3.
Best glide: flap position 0°
4.
Fast flight: flap position 0°
In turbulent conditions, the flaps should be slightly engaged. This increases the righting moment of
the wing and thus safety

Trim Speed
Caution: At low trim airspeeds there is a risk of causing a stall with even slight movements
(see also chapter 6.5.1).

-
Airspeed too low. Recommended approach airspeed is 31 - 43 mph.
For landing, the flaps should be set between 15° (strong headwind) and 70°, since the lowest
minimum speed is reached in this area
.
Important
: To lock the flap rope in the cleat, throw the rope forward over the basetube. In this
position it cannot come loose even if the rope is accidentally pulled
.
Important
: Pay particular attention to moving your hands to the downtubes with the landing flaps
pulled. Never change your hands in a turn, only on a straight final approach!
Attention
: With the flaps pulled for landing, the basetube does not have to be pushed as far forward
in order to stall. Although this makes it easier to flare when landing, it can also lead to an unwanted
stall near the ground if you are not careful. For this reason, always approach with a little extra
airspeed, let the glider settle over the ground and, when the minimum airspeed is reached, push out.
The easiest way to regulate glide path is with the flap fully deflected and varying your airspeed.
During your first landings, it is recommended you set the flaps at a sufficient height to fly a spacious
approach adapted to the conditions. The period for flaring is long. However, it is advisable to flare
late and vigorously to avoid climbing out.
Mistakes to Avoid
:
-
Flying the approach too fast in combination with large control movements leads to yawing.
-
Adjusting the flaps during the landing approach without looking at the targeted touchdown point.
The ATOS-VRS LIGHT can optionally be equipped with a variable tail unit. The movement of the tail
is linked to the operation of the flaps. If the flaps are off, the tail unit is in the lowest position, giving
low bar pressure). As the flap cord is pulled, the tail unit moves up a little before the flaps deflect.
This allows the pilot to tilt the tail a little in turbulent air, which increases the bar pressure or wing
righting moment, thereby increasing safety
.
On a VRS equipped with a carbon fiber keel, the tail tilts
until the flaps reach about 70%. At this point the tail returns to the lowest position enabling easier
flaring for landing.
