View Full Version : J5 Speed question

The "never exceed" speed limitation for a J5A is 104mph for climb and cruise, and 140mph for descent. The question of the day is -- Why the difference?

My old J-5 showed the top of the green arc as 104 mph. The yellow went from there to around 140, which was red-line.
I think we are talking about Vno and Vne in this case.

That would seem logical, but my aircraft limitations specifically state 104 for climb and cruise, and 140 for descent. (Since I have a larger than original engine, the plane could exceed 104 in cruise if I let it.) Maybe Vno and Vne weren't terms in 1941.

I think it is a typo in the TCDS. No other TCDS has that verbage in the cub TCDS.
