Hi everyone,
Just wondering why Beechcraft would have chosen the T-Tail config for the Beech 1900.
I realize it's an outgrowth of the King Air (where there are many T-Tails and conventional tails, depending on the series and production year). Even the 1900's immediate airline successor, the Beech 99, had a conventional configuration tail.
Off of the top of my head, it seems that the possibility of a deep stall situation would argue against the useage of the T-Tail config, however there must be some overriding design reason why the Beechcraft engineers went with the T-Tail.
Thoughts on this, anyone? It seems Beechcraft has loved playing around with the tail configuration ever since they first applied the V-tail to the Bonanza

T-tail? Almost a biplane tail... with vertical surfaces everywhere, too. I don't know the answer, but it looks as if some problems didn't want to go away.

In the late 1980's into the 1990's, if you wanted to make your plane look up to date, winglets and strakes were the way to do it I've often wondered about the "taillets" (on the horizontal stab) on the BE 1900 too...is this a drag-reducing sort of thing?

The reason that the 1900 has a T-tail and all the other appendages is that management wanted to use as many Super King Air 200 parts as possible. The tail itself is identical and the appendages (little vertical "tailets" and horizontal "horsals") were to add enough tail area to get the required levels of directional and longitudinal stability on the 1900 and 1900C. On the 1900D, ventral fins were added to compensate for the directional stability reduction due to the taller fuselage.
In addition, the 1900/1900C fuselage is a stretched cargo-door Super King Air 200's. On the 1900D, it was stretched vertically. The wing panels outboard of the nacelles are from a Super King Air 200. The outer wing panels are actually slightly modified Bonanza wings!

Is it just me, or did the photos that you cited reveal that the "tailets" also need de-ice protection?
