It looks like the new CIVL certification statement (and
categories) solves the prototype problem

I have wondered why Dennis Pagen would encourage CIVL to abandon
prototypes when the provision was used to allow Wills Wing certified production
gliders to be flown by the US National team in the 2009 Worlds in Laragne,
France, and Moyes Litespeed RS's to be flown in the 2007 Worlds in Big Spring,
Texas.

Well, it is because other changes have been made to avoid these problems.
Here is what Heather Mull, the Australian representative writes:

• Clarifying the definition of a prototype (discussed in hang
gliding and paragliding committees)

Three categories of hang glider proposed for Cat 1 events: Certified gliders,
non-certified gliders that are 'in production' and Prototypes - see descriptions
below. There was a Dutch proposal to ban prototypes from Cat 1 events – in
short, to improve fairness - so that pilots have access to the same type of
gliders – and also possibly improve safety. The intention is not to stop
development, so it was felt that prototypes should be allowed in Cat 2 events.

The Plenary voted in favour: no hang gliding prototypes will be allowed into
Category 1 events – to come into effect from 1st September, 2010.

1. Certified Gliders – hang gliders of a make and model for which there is
airworthiness approval issued by either the BHPA, DHV or HGMA and which have not
been altered in any way since manufacture that would affect this certification.
Sprogs must be set within the certified range.

2. Uncertified Gliders – production model hang gliders which have been available
for sale for minimum 4 months and have not yet obtained airworthiness approval
or certified models which have been altered from the certified configuration
(see S7 12.1.2.2 for Cat 1 entry requirements).

3. Prototypes – all other gliders (see S7 12.1.2.3 for Cat 1 entry
requirements).

This is combined with the new certification statement that pilots
will sign at the Worlds:

CERTIFIED GLIDER STATEMENT

I, the undersigned, declare that the Class ___ glider
___________________________ (make) __________________ (model) I will fly in the
_______________________________ (Name of event) _____________________
Championship, from _________ to ___________ (dates) is a model certified by one
or more of the internationally recognized certifying bodies (namely the DHV,
HGMA or the BHPA). Furthermore I declare that I have not altered the
configuration of the glider since purchase, in a manner that would take it out
of certification, and as far as I am aware it is in certified configuration and
I undertake not to alter this configuration during the championship. I
understand that I am the sole individual responsible for the integrity of my
glider and to the best of my knowledge it is damage free and airworthy.

I asked Mike Meier and Steve Pearson at Wills Wing about the above Certified
Glider Statement. Steve wrote:

I like it, but more importantly it sounds like our chief counsel
has signed off on it.

Mike likes it too.

The Uncertified definition above solves the problem that Moyes ran into when
their gliders were tested but they hadn't received the paperwork back from the
DHV.

The statement above reflects wording that I sent to CIVL (and others) before the
2009 Worlds.

So I apologize to Dennis for what I said about him regarding this issue. It
looks like this whole issue has been solved.
