This landing pattern computer is an easy to use popular plastic circular calculator. Pocket size, this calculator is only 100mm in diameter. Left hand patterns are on one side of the calculator, right hand patterns on the other.
The desired runway heading is located in the runway window which automatically co-locates headings for cross-wind, down-wind and base legs. The aircraft heading can be set with the cursor on the outer compass rose enabling the pilot to select the most convenient circuit join method.
Contrasting yellow and black scales enhance clarity.
