Todd - I read your post with great interest since I have 55 + 18 gallon
tanks for my -6a which have yet to be put to use. I was expecting to read
how you threw out the textbooks before landing, but then that would have
been a serious test of balance. you should have put 16 gallons of water
back there and one of your EWP's! you could get rated for fire fighting and
make big bucks. sounds like my 2400nm trip to the round up may not win an
award now. (hey, they never said anything about the lyc. part)

Subject: [FlyRotary] Gross Weight climb test
Today I did my gross weight climb test which is required in Canada (not
sure if it is in the US). I was a little nervous about it, but everything
went great. I loaded up all 6 tanks for an 84usg total strapped down a
backpack full of climbing gear and an inflatable boat (100 lbs total) into
the cargo, then filled a large hockey bag with my tech books from the last
several years of school (128 lbs - I guess they were good for something),
which I was able to buckle securely into the passenger seat. The formula
that I used to determine minimum climb rate, worked out to 890' in 3
minutes, which I was certain I could attain.
Gross weight was 2108 lbs and I rotated at 85mph using full power (6psi
boost). Initial climb rate was 1500'/min, slowing to 1000'/min. I held
this
steady until my temps (both oil & water) exceeded 210F (in 2 minutes) then
I
reduced power for the final minute of the test for a final result of 2400'
in 3 minutes. I'd like to see a little better cooling, but considering the
weight I'm satisfied that the test was easily passed.
The aircraft was very stable at this weight, so while at altitude I did a
clean stall, then checked power off descent rate (900'/min). I was
uncomfortable landing at this weight, as I had planned the extra fuel to
be
used only for long flights, but to I just didn't have time this weekend
for
a long flight. It turned out to be a non-issue thanks to my AOA
indicators.
As I fly all my approaches by AOA instead of airspeed, the speeds were
perfect and I just greased it softly onto the runway. It went so
perfectly,
I won't feel nervous at all about doing it again when the time comes for
me
to do a long cross country/ocean trip. (maybe non-stop to Oshkosh - next
year)(or 1 stop to the round-up :-)
