| Subject: | What's Your Contribution Used For? |
Dear Listers,
You might have wondered at some pointd, "What's my Contribution used for?" Here
are just a few examples of what your direct List support enables... It provides
for the expensive, commercial-grade Internet connection used on the List.
It pays for the regular system hardware and software upgrades enabling the highest
performance possible for List services such as the Archive Search Engine,
List Browser, and the Web Forums. It pays for over 21 years (yeah, I really
said *21* years) worth of on line archive data available for instant search
and access. And, it offsets the many hours spent writing, developing, and maintaining
the custom applications that power this List Service such as the List
Browse, Search Engine, Forums, and Wiki.
But most importantly, your List Contribution enables a forum where you and your
peers can communicate freely in an environment that is free from moderation,
censorship, advertising, commercialism, SPAM, and computer viruses.
It is YOUR CONTRIBUTION that directly enables these aspects of Matronics List services.
Please support it today with your List Contribution. Its one of the
best investments you can make in your Sport!

My RV7A, after nearly nine years, is just about ready to fly. I have been taxiing
around and managed to iron out a couple of small bugs. The only big hurdle
left is the final inspection. I think I have all the paperwork in order but there
is one conundrum.
An old boss once told me if you copy someones work it is plagiarism; if you use
more than one source it is research. I have done extensive research and with
my own input have come up with Normal Operating Checklists (one page two sides),
Emergency Checklists (two pages totaling 3 sides) and a Pilots Operating Handbook
(now at 100+ pages and growing).
In my Emergency Checklists I have three occasions; for CARBON MONOXIDE FUMES, CABIN
SMOKE REMOVAL and DITCHING, where I have stated either Canopy.... Unlatch
or Canopy.... Slightly Open. Then, I added a WARNING... Unlatching the canopy
in flight may result in separation of the canopy from the aircraft.
What do we know about flying an RV6, RV7 or RV9 with the canopy open? Has anyone
ever done this? Has anyone ever intentionally opened the canopy in flight? Has
anyone ever had a canopy separation from the aircraft? This is again just part
of the research.

I assume that you are talking about a slider. I had mine open up once just
after take off, due to me not following the checklist. It opened up about
15cm and then stopped. I could close it with one hand, after stabilizing the
aircraft in cruise flight. On the other hand we had a crash of an RV9 at a
neighboring field due to the same oversight, details not known to me
Cheers

I don't think you will have any major issues (except underwear
laundering) with either the tipup or slider. Sliders will typically open
a few inches & you can't force them any farther open while at normal
speeds. Tipups will rise a few inches in the rear (no more) & can't be
pulled closed unless you slow down a lot & deploy the flaps.
I've seen some forum chatter supporting my slider statement, but I can't
point you to any slider references (checking with Van's is always the
best policy on safety issues anyway). A friend has tested the tipup
(can't remember if it was a 6A or 9A; he's built both). He got the
results detailed above.
The -4 with tipover is another matter entirely. If the safety doesn't
catch it, it will 'unzip' the hinge rivets. (This is a design feature to
allow the canopy to depart if the occupants need to follow.)
Hope that helps,
Charlie

Thanks for the comments. My 7A is a slider.
