Tim,
I may be well off-base for this but, there was a
Canadian-built Europa which was created in Calgary, Alberta and registered
with a Max T/O weight of 1500lb. This I'm told is the result of the rule
which bases the MTO on the wing area, thus permitting a higher weight than
PFA-regulated machines.
Consider this move at an airfield 3500 ft ABL and reaching
summertime temps of over 35deg C. The builder gave me this info at OSH when
we met at the Eur tent. He said they took off at max weight at 35deg many
times and had no trouble with that (he was not a tyro) so it appears that
greater latitude prevails here. Naturalluy one can register at a greater
weight, but use it only for planning for a smooth-air trip for
endurance/range, and still qualify for aeros at a lesser weight. What
overshadows things here is that the ever-voracious givvermint taxes aircraft
annually on its weight. Thus lesser registered weight results in a lesser
financial burden (for the life of the 'plane). Just as a pound weight saved
lasts for the life of the machine, a dollar saved does also. We now pay
taxes on taxes on taxes, so you can imagine the calcs.
Good luck,
Ferg

Subject: Europa-List: Increasing Max T/O weight in Holland to 1450 lbs/ 657
kgs

| I spoke Andy Draper about weight and balance calculations. He told me that
| the 1370 lbs max T/O weight of the Europa is based on structural tests to
| 8,55 G loading with 1370 lbs of weight. This figure is decreased by a
normal
| safety factor of 1,5 for composite structures (which gives a G limit of
5,7
| G ) and an other 1,5 "PFA superfactor" which is not a CAA requirement but
a
| PFA requirement. That PFA based extra "Superfactor" gives the limit of 3,8
G
| in our books. The "Super factor" is not used for normal certified VLA
| aircraft, only for Experimentals in the UK because of this PFA rule.
|
| In the USA and Canada there is no Superfactor of 1,5 times required for
| experimentals. Andy told me that due to this there are Europa's flying in
| the USA and Canada with a max T/O Weight of 1450 lbs (or 657 kgs). I would
| like to try to increase the Max. T/O weight of my Dutch registrated Europa
| also to 1450 lbs in my Permit to Fly, but to get it in my Permit to Fly
the
| Dutch CAA is requiring a copy of a Permit to Fly from an Europa in the USA
| and/or Canada with the 1450 lbs figure on it.
|
| Is there someone with this type of Permit to Fly who can sent me a copy
| (scan via email) to be able to increase the Max T/O Weight for Europa's in
| The Netherlands to 1450 lbs as well?
| Thanks!
