3. Flying the Boomerang 10
The Boomerang 10 was developed for performance and competition pilots with extensive flying
experience. The basic types of flying described below should be second nature for such pilots,
but have been included in this Manual for the sake of completeness.
Preparation for launch
A careful pre-flight check is required for any type of aircraft. Make sure that you exercise the
same level of care each time carry out the check. Following a consistent method of preparation
and pre-flight checks is vital for safe flying. We recommend the following:
 On arrival at the flying site, assess the suitability of the conditions: wind speed and
direction, airspace, turbulence and thermal cycles.
 Inspect your glider, harness, reserve handle and pin, helmet and any other equipment.
 Choose a sufficiently large take-off area with even ground and no obstacles.
 Lay the glider out according to the plan form, and get the lines and risers sorted out.
 Put your helmet on. Secure yourself in your harness and don't forget the leg loops!
 Connect the risers to your harness carabiners, ensuring there are no twists or loops
around the lines.
 Connect the speed system to the risers with the Brummel hooks.
 Do a final line check by pulling gently on the risers or lines to ensure there are no new
knots, tangles or interfering branches or rocks. Take extra care in nil or light winds.
WARNING If there are obvious folds in the glider because it has been tightly packed or stored
away for a long time, then the pilot should carry out some practice inflations before
first launch and smooth out the trailing edge a little. This ensures that the flow
profile is correct during launch. It is particularly important in low temperatures that
the trailing edge is smoothed out.
5-point check
The 5-point check is carried out immediately before launch to check once again the most
important safety points. It should always be carried out in the same sequence so that nothing is
overlooked. The 5 points are:
1. Is personal equipment correct (harness, carabiners, reserve, helmet) and are all
straps done up?
2. Is the canopy arranged in a half-moon shape and are all the air-entrances open?
3. Are all the lines untangled and are any lines under the canopy?
4. Does the weather, in particular wind direction and strength, allow a safe flight?
5. Are the airspace and launch area clear?
