Sport Pilot Final

Actually, 45 knots = 51.75 mph, so it looks as if the 415C should be able to
have the SLA classification. That's a good thing, cuz many of the other
"eligible" a/c are tail-draggers. The castored main gear on the Ercoupe
should make a crabbed X-wind landing fairly easy (and necessary since
auto-coordination excludes slipping.)

news
I have heard conflicting reports as to whether the Ercoupe 416C would
be eligible as a LSA or not. Anyone know for sure? I see it listed as
having
a
t/o weight of 1260 lb. under the 1320 lb. in the newly published FAA
rules...

Looks to me like your in....

Stall speed (clean) 48mph

LSA stall speed 45knots = approx 48.6 mph

Somewhat on topic, is it possible to change (lower) the gross weight
of a production aircraft? Example a piper clipper pa-16 is of course a
4 seater empty wight usually around 900 lbs, if I removed the back
seat and flew it at 1320 lbs or under (my wife and I together weigh
300 lbs or so)? It would meet all the other criteria vne 120 knots or
less, cruise and max speed 120 kts.

Thanks,
Dave

That would be closer to 51.7864910 mph.

Sure. Recertify it.

In Idaho, tossing a rattlesnake into a crowded room is felony assault.
In Tennessee, it's evangelism.

NO,

Well, YES, actually, but it will not do any good for Sport Pilot.

The FAA added the following to avoid just such a thing: "Light-sport
aircraft means an aircraft, other than a helicopter or powered-lift that,
since its original certification, has continued to meet the following:"

The words "since it's original certification, has continued" is your
problem. The same for the ercoupe 415 d's that used to be "c's". You
can't take them back to a "c" and fly under sport (and be legal). I
suppose it's unlikely that a ramp check will get you ... but if the ramp
checkers start carrying laptops with N-number databases in them... maybe
you would get caught.

Actually, NOT in the U.S.A.. [Pun intended]


Since 1959, the U.S. has used 6,076.115 feet
as the international standard for a nautical mile,
making 45 knots closer to = 51.78507102 mph.

However, there are other standards for a n.m.
Therefore... YMMV. g

Ah, yes. Careless reading on my part.

The castored main gear on the Ercoupe

Ercoupes don't have castoring (swiveling, turning, rotating) main gear
(legs). They are simply robust enough to take the side forces
generated by a crabbed landing.

AAARGGH...one was enough. Two is too many.

Castoring means you are extracting the oil of the castor bean.

Castering means that something swivels.

This is not true. The main gear does rotate to compensate for crabbed
landings.

sorry, my first calculation was Knots with tax (grin). Or maybe I'm just
not tying them right.
