Trident reverser on landing - clarification
Dtype, Herod, DaveReid, topgas: for clarification and to avoid thread drift.
On the Trident the pods ONLY had reversers. It was allowable to select up to 10,000 rpm in reverse in flight for expedited descent. The NORMAL landing procedure was to select reverse IDLE in the flare. It was possible to select full reverse in the flare, and recommended to do so in some conditions such as short or wet runways - the Gripper did not have good brakes.
The reverser position was not a flight recorder parameter, at least not in the 1970s. This had some interesting consequences after a minor incident, including nearly scuppering NASA’s ASRS programme. But that’s a different story altogether and won’t be going here!
