Trainer options for Big, (and fat), guys

This will be a problem.
JAR 22 standards seem to limit all pilot stations to a max of 242 pounds.
A 2-32 may be your only option.

242 lb (110 kg) is the *minimum* weight, not the maximum. The fact that no one allows for over the minimum is not a problem with the standards...

Ahhhhh, Marc.

LS-8 Flight Manual, page 2-6, Paragraph 2.9 Flight Crew.
"Maximum cockpit load (Pilot+parachute+baggage+temporary equipment)....110kg, 242 lbs."

Ahhhhh, Marc.
Flight Manual.
Schleicher ASK21 approved March 9, 1983.
Page 13. Paragraph II.8, Weight & Balance Information.
"Max. payload front seat (pilot incl. parachute): 242 lbs = 110 daN."
"Max. payload rear seat (pilot incl. parachute): 242 lbs = 110 daN."

Ahhhhhh, Marc.

Flight Manual Grob 103.
Page 6, paragraph II.8 Load scheme "TWIN II"
"Maximum load in the front seat . . . . 110 kg (242 lbs)"
"Maximum load in the back seat . . . . 110 kg (242 lbs)"

English is not an easy language. To be more precise, the minimum "maximum" pilot weight permissible under the JAR22 standard is 110 kg. That does not mean that JAR22 gliders are not permitted to have a higher "maximum" pilot weight than 110 kg, what it means is that none of the manufacturers (Genesis 2 is the sole exception, I believe) have chosen to provide over the minimum for the maximum pilot weight. Clear?

Ahhhhh, Marc.
Maximum means, "not to exceed."
It is not a "guideline." It is not "advice."
But, you are the pilot in command.

Paraphrase of relevant section provided years ago by Bob K.:

: JAR 22.25 Weight Limits
:
: (a) Maximum weight. The maximum weight
: must be established so that it is:
:
: (2) Not less than the weight which
: results from the empty weight of
: the glider, plus a weight of occupant(s)
: and parachute(s) of 110 kg for a
: single seat glider or 180 kg for a
: two seat glider, plus the required
: minimum equipment, plus any expendable
: ballast and for a powered glider
: sufficient fuel for at least half
: an hour of flight at maximum continuous
: power.

Please note "not less"...

That is an interesting piece of writing, BUT
The individual aircraft flight manual is the authority on weight and balance.

I think what you are trying to rationalize is a situation where a pilot weighs more than 242 pounds but when you do the math the aircraft loading is still below the maximum non-lifting load limit, below the maximum all up loading, and the aircraft is within C.G. limits. This is always an interesting discussion.
However, the aircraft flight manual is the authority for each individual aircraft. Perhaps things like the design of the seats and backrests are some limiting factors in the maximum pilot weight of 242 pounds.
You should ask the manufacturer what their opinion is.
You should ask the FAA via the local FSDO office what their opinion is.
Let us know what you find out.
