So, presumably that could leave the impression that agressive use of the 707 rudder would be okay below 250 kias or even above 250 if the pressured reduced.
It was somewhat academic at my airline since we were never taught to use the rudder for anything other than takeoff or landing or engine failures.
Aterpster,
no airplane is designed to take rapid aggressive oscillating inputs on the rudder [or other flight controls...even below Va...it's a structural issue..in fact from a maximum sideslip condition just centering the rudder imparts massive loads
this conversation is too hot for me so I'll go back to lurking and enjoying...
