Tips for the take-off

Practice ground-handling regularly to improve your take-off skills!

If the glider comes up slightly off-centre, make small corrections by moving towards
the lower side.

In stronger winds, take only central A-main line per side over rapid links in one hand
and the outermost B-main line per side in other hand while you hold brake toggles in
your hands. Pull on A-lines and control the speed of rise with the B-lines. Be prepared
to take a couple of steps towards the canopy. By a good procedure the wing tips
cannot rise earlier then the centre of the canopy.

The pilot must work actively to keep the glider on the ground in higher winds
(wind speeds from approximately 6 m/s), otherwise the glider may rise above the pilot
unintentionally.

During reverse launch and ground handling, care should be taken that the brake lines
do not rub over the riser. This may cause damage to the riser or lines.

If you let the brake handles go out of your hands during take-off, take care that the
brake line is not twisted around the low friction ring.
Flying it
The glider is delivered with a standard set-up and its trim speed can reach 37 - 43 km/h
depending on the weight of the pilot. Trim speed (brakes fully released) is the best glide
speed in calm air. The brake lines are used to adjust the speed according to the flight
situation in order to ensure optimum performance and safety. Minimum sink speed on the
Aravis is achieved by light braking. During your first few flights, familiarize yourself with
your glider’s speed range and corresponding brake positions and pressures.
NOTE! Always fly with sufficient clearance from the terrain and always keep the brake
handles in your hands!
NOTE! Flying too slowly close to stall speed increases the risk of an unintentional
asymmetric stall or full stall. This speed range should therefore be avoided and used only
on landing during the final stage of the flare.
Accelerated Flight
The Aravis is very stable in accelerated flight. C riser control is very effective up to 60 % of
speed bar range. By more than 60% the effectivity decreases. When flying fast than that,
we recommend to control the pitch of the wing actively using a combination of the speed
bar and C riser input. If you feel the nose of the wing start to collapse the first action
should be to release the speed bar impulsively and then make any necessary C riser input.
Release the speed bar first before making any C inputs. Using the combined active speed
bar/C riser control technique you will be able to maximise your speed and glide efficiency
whilst minimising the likelihood of collapses.
Attention: Do not apply brakes when fully accelerated! Braking increases lift near the
trailing edge. The main lift point moves backwards. Due to this the wing can lose stability
for a short time!
