I was going to say, I do not recall a PBA although there is a Pitch Boost
Actuator which does nothing but dampen the feedback in the pitch axis much like a shock absorber. However the thing does no offensive work at all like the collective boost actuator. Fred "B2431" wrote in message ... Take a look at the Puzzle Palace aka the Pentagon. There are people there who have no concept of reality. Next, take a look at the aquistion process. There are no procedures for asking contractors to keep things simple. When we first aquired the UH-60A the Sikorski reps and brochures said that the helicopter had been designed with "maintenance in mind." Despite the pretty pictures in the brochures and the friendly reps no one ever said that meant they intended to make life easy for us. My favourite example was the pitch bias actuator. The PBA was a little box about 8 inches long, 2 inches thick and 4 inches wide. The PBA was mounted in the middle of the mixing unit and was a bear to replace. It was perpetually failing and was ultimately eliminated with no noticable change in handling. Dan, U. S. Air Force, retired |
