Came across these drawings and explanations in a 1938 Newnes Airframes technical manual. Hope they might be of interest……….
I remember a few years ago someone registered a cast-iron manhole cover with the CAA.
It’s most unfair to refer to the FRED like that. It only glides like one!! 😀
Here are the relevant pages from the Air Ministry manual……
PM me with your e-mail address if you want a pdf sending to you……
It all depends how naturally stable in roll the aeroplane is.
Something like a Cessna 152 / 172 / 182 will probably plough on in a straight line quite happily, till given a boot of rudder.
I used to have an Aeronca Chief derivative that would fly all day on rudder-only control and the trimmer was powerful enough to substitute for the elevator.
In fact putting in aileron input generated so much adverse yaw that it was almost more trouble than it was worth!
Mind you, I wouldn’t advocate trying aileron-less control in something like a Pitts!!
Pushpak aka Aeronca Chief. Loadsa roll, little aileron!
