Title: "Q" inlet heater
Post by Jan Koppen on May 1^st, 2012 at 6:44pm

Gents

On which place can I find the "Q" inlet heater on the 707-320B ?
Is discussed in the Min. equipment list for the 707.

Have discussed the matter with KLM tech. specialists.
Interesting piece of artwork to get/or not to get a feel of the rudder.

They were also installed on USAF KC-135's. Provided artificial feel to the hydraulic boost on the rudder pedals. It was calibrated to the current airspeed. There was also a manual reversion switch in case of emergencies.
