He publish flight safety advice to pilots explaining:
• How features such as valleys, VFR lanes or edges of controlled airspace constrain aircraft onto similar courses and concentrate traffic density;
• How similar performance aircraft may converge laterally or vertically where lookout is most difficult;
• What steps to take to compensate for this difficulty;
• That an essential part of visual collision avoidance is a low traffic density. Good airmanship includes consideration of when and where to fly, with this in mind.

The Acting General Manager accepts sub paragraphs one, two and three of this recommendation and has accepted an offer from one of the operators at Queenstown to assist in writing an article for publication in the Safety Digest.
The wording of sub para four is not completely accepted. It is possible to have a safe procedure for collision avoidance in a dense traffic flow and this is applied in many areas in New Zealand. We would rewrite para four to read: "Good airmanship is an essential part of visual collision avoidance in both a low or a high traffic density situation and includes consideration of when and where to fly."
