Dunno about 38, but the newer ones have 30, because full 40 degree flaps were
causing problems (which I can't recall) due to poor technique of some sort.

Might have something to do with slips with flaps, IIRC.

Yep, slips with flaps was part of it, but a nose high attitude with
full flaps on go-around is what bit most of the people before they
changed to 30.

This month's edition of Flying has a good article by Richard Collins
about landings and a lot of the article is devoted to the use (or when
appropriate, the non-use) of flaps

If you are referring to the May issue (we don't all receive our issues
at the same time) then no it doesn't.

It does have one by Tom Benneson though on page 84.

There's a lot in that article to which I take issue.

Mr. Halstead,

The article to which I was referring to is entitled "The Grand Arrival
Takes Time" on page 56 of the June 2004 issue of Flying . It was
written by Richard Collins.

I don't remember reading the article you refer to and I have already
given my copy of the May issue away to a friend.

When you get the June issue, read the article. It would be
interesting to know what you think.
