OK.

I don't see what is ambigous about "it must depend on the wind"

I did read the post and if you think that's what you said, then so be
it.

Mike,
Actually, niether Vbg nor minimum sink is correct in all
circumstances. Vbg will yield the greatest distance by definition,
and minimum sink will yield the greatest time. Which one is the most
beneficial? Gotta look at the circumstances. There is a good
discussion at http://www.auf.asn.au/emergencies/aircraft.html#vbg

I had a primary instructor who insisted that the best speed to use in
the event of an engine failure was the published best glide speed. I
said that it must depend on the wind and pointed out that if there
was a headwind equal to Vbg that any speed over the Vbg was better.
I also pointed out that with a strong tailwind that the minimium sink
speed would get more distance. He continued to insist that Vbg was
the speed to use. That was our last flight.

We all harbor misconceptions but there is no excuse for being too
stubborn to learn.

No, Actually, he's not (unfortunately).


Well, he had to get the idea they were ground speeds somewhere.
The timing table is pretty much the only possible source.

His reasoning is that the faster we're moving across the ground,
the faster we'll move outside of the protected area, for example,
on the circling maneuver, and that to use the higher minimums
'just made good common sense'.

However, he's interpreting the rule using this 'common sense'
and claiming that this is what the rule implies.

He made it clear to me that he was talking about the approach
category minimums and not just the time from FAF to MAP (which,
of course, is based on ground speed).

This CFII is stupid. Once you start circling the winds change and
will become a headwind at some point.

Ya know ... I mentioned this to him as well. However, I think he's
stuck on the Ground Speed reported by the GPS during the final
approach as being the speed used to determine the approach
category... That's just not what the FARs say.
