Re 600 Foot Pound last Message.
The original JT9D on the B747 had a bar installed aft of the thrust levers. Never used by ground engineers but was for flight crew only. It was known as the 'Bodie Bar' after a pilot in the USAF who did slam accelerations and deccelarations of engines. So I was told on an engine course. It was to prevent the engine going below a certain R P M possibly to avoid a slow spool up. Does anyone recall this ???.
