Standard Overhead Join

Most pilots carry out overhead joins correctly and safely. However, incorrect overhead joins do get reported – and while some involve visiting aircraft, several close calls have occurred where incorrect joining procedures created the potential for conflict. Here's a clarification of the correct technique.

At aerodromes that operate both left-hand and right-hand circuits, such as Foxpine and Omaka, the overhead join requires aircraft to approach and enter the overhead with the aerodrome and runways kept on the left-hand side.

Once established overhead, you have several options:

• orbiting overhead (left-hand only)
• joining the circuit
• vacating the area if required

The standard overhead join is designed to maximise wings-level time in the overhead and in the circuit, allowing an effective lookout and better situational awareness.

Why it matters

A conflict can arise if one aircraft enters the overhead correctly with the aerodrome on its left, while another enters overhead intending to join a right-hand circuit with the aerodrome on its right. The two aircraft may be on converging tracks with limited ability to see each other – a serious collision risk.

In summary

• If an aerodrome has both left- and right-hand circuits, always enter the overhead with the aerodrome and runways on the left.
• If a right-hand circuit is in use, fly clear of the overhead before repositioning to join the right-hand circuit.
• Continue to descend on the non-traffic side, make the same radio calls, and fly the same overall joining pattern.

If you're unsure about the procedure, have any questions or would like a refresher, have a chat with an instructor before departing. A short revision flight is also a great way to rebuild confidence and make sure your procedures are current.
