- Available patterns:
- From F1 to F2: 15-NM radius - 15-NM radius - both ways
- From F1 to F3: 15-NM radius - 15-NM radius - both ways
- From F1 to F4: 15-NM radius - 15-NM radius - both ways
- From F2 to F3: 15-NM radius - 15-NM radius - both ways
- From F2 to F4: 15-NM radius - 15-NM radius - both ways
- From F3 to F4: 15-NM radius - 15-NM radius - both ways
- Unless restricted, default orbital direction is anti-clockwise. When inverting orbital direction, the associated inbound/outbound legs are inverted as well.
