Cloud flying and unauthorised aerobatics are prohibited. Any manoeuvres hazardous to others shall be avoided and may be penalised and competitors shall avoid dropping water ballast in any manner likely to affect other competing sailplanes
A briefing shall be held each morning, during the training and championship flying periods, at which full meteorological and operational information appropriate to the task of the day shall be given. This shall include units of measurement and times as appropriate if not already stated in the Local Procedures.
a. All pilots shall attend briefing except that a competitor who is unable to attend, for reasons outside his control, shall be represented by his Team
Captain.
b. Flight and safety requirements given at briefing shall carry the status of Local Procedures.
All flight and safety requirements should be provided in writing for the Team Captains.
The following limitations are imposed so that the competition shall, as far as possible, be directly between the individual competitors, neither controlled nor helped by external aid.
5.3.1 Radio Transmitters and Transceivers Radios are for voice transmissions between team members and between them and the Organisers only.
a. They may not be used to contact Air Traffic Services other than for obtaining permission from an airfield to land on it, unless the Organisers add specific requirements in the Local Procedures.
b. Any other data transmission between competitors, or between them and the ground, except as required by the Organisers, is prohibited.
c. Transmissions may only be made on frequencies prescribed by the Organisers.
d. The Local Procedures shall designate common radio frequencies that shall always be used by competitors for flight safety.
A single frequency should be designated for the launch, start, finish, and landing. One frequency should be designated for each Class flying within a common task area.
To improve safety, competitors should maintain a listening watch on the designated frequencies, especially during the launch, prior to starting, while finishing and landing, and when thermalling with other sailplanes.
5.3.2 Other Types of Aid Leading, guiding, or help in finding lift by any noncompeting aircraft is prohibited. Competing sailplanes abandoning their task or still airborne after cancellation of their task must land or return to the competition site
without delay and may not lead, guide or help in any way competitors in other classes still flying their assigned task.
Flights shall be controlled by GNSS flight
recorders (FR).
a. All GNSS FR’s approved by the IGC up to two months prior to the Opening Day shall be accepted. A valid calibration certificate must be provided for
each FR.
The FAI SC Section 3 requires that Flight Recorders have been calibrated within the previous 24 months.
b. Two GNSS FRs may be used. One being designated to the Organisers as the primary recorder and the other one as a back-up.
c. GNSS FRs recording intervals shall be set to 10 sec or less. Non-compliance may be penalised.
d. FRs shall be switched on for at least two minutes before take off to establish an altitude baseline. On motor gliders having an MoP capable of being
started in flight (including sustainer MoP) the engine must be started and run for a maximum of two minutes either before the launch, or as soon as
possible after release if the motor glider is launched by aerotow. This is required to provide a positive record on the GNSS trace. The FR must
remain switched on following an engine run on the ground.
e. If both recorders fail and the flight record is interrupted for a period longer than one minute, then the glider shall be considered as having outlanded unless satisfactory evidence can be provided that the glider did not, during the interruption of the FR record, violate airspace or, in the case of a motor glider, use the MoP.
f. The Organisers shall require the backup FR only in the event that the primary FR fails. The Organisers shall be informed of any change of equipment including the designation of the primary FR. Non-compliance may be penalised.
5.4.1 Penalties may be imposed by the Organisers for unauthorised interference with the GNSS equipment, data or internal program.
