Q

Reverse Thrust - Operational Limits

A

1) In flight, the use of reverse thrust is prohibited. Ground reverse thrust is limited to maximum continuous thrust settings.
2) Reverse taxiing is not permitted.
3) Reverse thrust must be serviceable for scheduled 30 metre runway operations, including alternates under the following circumstances;
Prior to initial departure for Extended Range Operation when any nominated Adequate Airport has a 30m runway. This shall not inhibit the aircraft from completing a return flight should any system(s) become redundant enroute, provided the MEL covers the redundancy.
