William Seger - Epically Fails - Again

9. Beachy - do you agree with this person?

Is Rod Machado wrong when he states -

"Many years ago, before oscilloscopes and sensitive vibration measuring devices were commonly used, aerodynamicists had a very basic means of identifying an airline's flutter speed. They'd find a skilled test pilot, show him a wheelbarrow full of money, then send him aloft to dive the airplane at dazzling airspeeds. The test pilot's job was to determine the speed at which the airplane experiences flutter.



When he returned-and when his breathing slowed and he regained his ability to speak-he'd tell his tale. He'd inform the engineers about the speed beyond which the airplane experienced flutter. This speed is known as Vd or design dive speed.

.....

That's why, in the spirit of safety, the FAR's require marking the airspeed indicator's red line (Vne - velocity to never exceed) at a point representing 90% of Vd. " - Source

After all, he is ATP rated and not listed at P4T.

So you should agree with him, right?

Or do you agree with Seger, a person who didn't even know what Vd was a little over a month ago....

Perhaps you think Rod is just a "journalist" as well?
