1.5 Factor Of Safety - FAR 25.303

Hi all,

Does the Factor of Safety of 1.5 under FAR Part 25.303 apply to speeds or just G-loads?

eCFR ? Code of Federal Regulations

In other words, is there a factor of safety of 1.5 above the speed Vne or Vd as well?

In further terms, looking at the following VG diagram, there is an "Overspeed margin" between Vne and the end of the flight envelope.

Does the "Overspeed margin" represent a Factor of 1.5 as well as the G-loadsl?



Thanks in advance.
