Section 3. PREFLIGHT INSPECTION
3.1. Do complete preflight inspection of the glider. Check all parts and all assemblies of the glider.
Beginning at the nose go around the glider, check all details of the construction. Finish inspection by
checking the keel tube and control frame.
The less you hurry the more you’ll inspect!
3.2. Check nose junction.
The wires must be hooked in and secured.
All bolts must be screwed and secured.
The keel’s pulley lever must have no bends, the control wire must go through the pulleys, the wire
safety brace must have no bents and control wire must do not have possibility to go out from the pulley
3.3. Check the tip area.
The sail corners must be properly attached at the tip.
The Velcro around tip strut must be fixed properly. There must be no wrinkles on the sail which do not
allow the SPADD’s front edge to fit snug to the sail.
The SPADD must turn easily, it should be impossible to remove the quick pin without pushing the
button
.
3.4. Check ailerons
Ailerons must turn easily, without extra efforts (to check this, unhook side wires, turn ailerons holding
them by the lever, to avoid damaging them).
3.5. Check aileron rod
The end of the aileron rod must be secured.
The quick pin which connects the aileron lever to the aileron should not be removable unless the button
is pushed.
3.6.
Check the rib N5 junction. Open the zipper at bottom surface.
The aileron rod must be fixed at the control quadrant (sector) and secured (locked)
Control wires must go through the sector.
Control wires must go through the turn pulley in the front part of the rib N5
3.7. Check rib’s tips position
Walk along the trailing edge and check rib tips position.
The trailing edge tube must be supported at tip rib pulleys
3.8. Check the flaps deflection.
They must turn easily, without extra efforts.
After unfixing flap control rope flaps must go up easily and quickly.
3.9. Check the root area.
The trailing edge tube pins must be secured
The bolt fixing the downtubes to the keel tube must be screwed
Open the bottom and top root zipper by two thirds of its travel.
The ribs tensioning wire must be locked and secured properly.
All control cables must go through the control pulleys
Control cables must not be jammed.
The RWG rod on the keel must be fixed and locked
The RWG rope on the speedbar must easy turn the RVG pulley and after releasing the rope the RVG
pulley must turn back
The stopper rope and rubber on the stopper rope must not be broken.
Hang-in belt must be secured by the bolt, the nut should be locked, the belt should have no damages
3.10. Check ailerons neutral set up angle
In neutral position the trailing edge of the ailerons must be on the same level as flap’s trailing edge or
~5mm higher
3.11. Check side wires attachment.
The side wires must be connected to the downtubes and should be impossible to remove the quick pin
without pushing the button
The side wire must have slack if the RVG off and must have no slack if the RVG on
3.12. Check control system.
Take the glider as before take off, move control frame right and left.
The control frame must move easily, ailerons and SPADD must move properly.
Section 4. PERFORMANCE AND FLIGHT CHARACTERISTICS
Check and adjust your harness. We strongly recommend that you hang as low as possible (as close to the
speedbar as possible). Be sure that no part of the harness touches the speedbar while pilot moves over the
whole range as he or she will move in flight.
4.1. Take off
