Aviation safety issues and actions
Recommendation issued to: Gliding Federation of Australia
|Date issued:||03 July 1997|
|Safety action status:|
The Bureau of Air Safety Investigation recommends that the GFA advise its members that the responsibility for collision avoidance when one glider is overtaking another rests primarily with the pilot of the overtaking glider. Information regarding the responsibility for collision avoidance, especially during competitions, should be published as a gliding Rule of the Air in GFA publications and brought to the attention of pilots by GFA instructors.

|Action status:||Closed - Accepted|
I refer to Air Safety Recommendation No 970094 on the midair collision which occurred on 24th January, 1997 between two gliders in the National Gliding Championships. I apologise for the delay in replying to the ASR and I thank you for the reminder on the phone today.
BASI has recommended in the ASR that GFA advise its members that the responsibility for collision avoidance in an overtaking situation rests primarily with the pilot of the overtaking glider.
We were under the impression that we had addressed the overtaking problem, both in our Operational Regulation 8.16, itself an extract from CAR 162 (3) and (4), and in our booklet "Airways and Radio Procedures for Glider Pilots". Given that pilots cannot see behind them, except to a very limited degree in very few types, it is strongly inferred in the regulatory requirements that the responsibility for collision avoidance cannot sensibly be assigned to a pilot who cannot see the threat.
Therefore it has always seemed to us to be quite adequate to mandate the overtaking side, with due allowance for hill soaring, the inference being that the pilot wishing to overtake is responsible for maintaining adequate separation. It would of course be possible to spell out the actual responsibility of the overtaking pilot for collision avoidance, but if this involves any changes to the CARs it might be more trouble than it's worth, especially with the present turmoil within CASA . Your advice would be appreciated on this matter.
I trust this clarifies the GFA position. We remain, as always, willing to discuss the matter further if you so wish.
ATSB Note: Following a meeting with [name supplied] on 13 January 1998 it was agreed that the wording of the GFA Operational Regulations be changed to include the intent of car 162(3) which states:"...the overtaking aircraft.....shall keep out of the way of the other aircraft......"
