Losing altitude
Should you encounter a situation where you need to descend quickly or the lift becomes to
strong, there are several ways of quickly getting down.
The best way is of course, to find sink. This is often forgotten in a situation of stress -
leave the lift!
Here are some examples on how to get down fast. We recommend you try them out under
qualified supervision during a safety training course over the water.
Big ears
Although the noise of the wind around your ears may imply it, the
groundspeed
does not
improve with big ears. On the contrary, flying with your glider’s ”ears” in will decrease your
maximum ground speed by about 6 km/h. It is however a safe method of moderately losing
altitude while maintaining some forward speed.
Pull in big ears with the outer A line on each side. Reach high into the lines and pull
outwards downwards. On releasing the lines, you might pump out the big ears with
Boomerang: they will only slowly come out on by themselves.
If necessary, keep the big ears in until you flare for landing instead of letting them out on
the approach. This is a safer method because of a possible wind gradient and your low
airspeed/high wing loading with big ears in.
Spiral dive
The Boomerang has a very effective spiral dive. Weightshift and pull the brake on one side
slowly. Let it accelerate for two turns and enjoy the roaring wind and high G-force. You can
achieve sink rates of up to 20m/s this way. Once you have entered the spiral you can control
your descent rate and bank angle with weight shift and the outer brake.
WARNING! A pilot not accustomed to spiralling and/or dehydrated, can quickly lose
consciousness in a steep spiral dive! Practice spiralling with caution and lesser sinkrates to get a
feel for the Boomerang´s behaviour. When exiting a steep spiral dive, let it decelerate for one or
two turns with outer brake applied and/or weight shift to the outside to avoid big pendulum effects
and deflations.
