Hmmm.
I think I have a comment worth posting on
the tail size.
Now, here in OZ I have a “large tail”
320.
Yet, it seems that there were two ways of
determining the “large tail” design when the local authority
demanded it.
One was to create a new 25% larger horizontal
stab with the elevator full width, and the elevator horns wrapped around the
ends.
The other was to extend the horizontal stab
the 25% while retaining the same elevator width. ( Thus, my request to Grayhawk
for a measure of the length of his tail – er, elevator - ahem!)
Now, at approach speeds, I find I run out
of pitch trim at about the point of stabilized approach with landing flap (30)
on final.
This means that the there is always an ever
so slight tendency for pitch down at that speed.
Which in turn means stability.
Now, Airbus, in its wisdom, and for those
who have flown or still fly ‘em know, decided Lancair had a great idea with this nose down pitch stability on
approach.
‘Cos
at 100’ on final, the elevator computer takes a snapshot of the pitch
angle, and retains that in memory.
Then at 50’ the elevator computer
commences a positive nose down pitch which demands the pilot commences a flare
into the landing.
Bloody marvelous mates.
Also I had the privilege of flying Bill and
Sue’s 320 at Fredericksburg last year, although I suggest Bill would
suggest the term, “fly”, is a gross exaggeration in my case, and
confess I couldn’t tell the difference between my tail and theirs.
What I found a mystery was the over-control
I exhibited in both pitch and roll axes. Mine is very stable in both areas.
