An Evolutionary Step Forward For A Revolutionary Airplane
Let's Get Rolling!
Sure... it looks like the front end of the StarShip Enterprise,
but the G2's starting system is pretty uncomplicated once you get
through the checklist, pop on the electrical (though one must note
that there is a lot more electrical to deal with than other
airplanes… since the SR22 has two separate electrical
systems), prime (if required) and fire the works up, advancing the
mixture as soon as you get the fire burning. Please note the
absence of a prop control...
The SR22-G2 started readily (with a truly magnificent, baritone,
full-throated, "I'm SO ready for business" kind of sound) and
required little priming as it was still warm from having flown in.
The Avidyne system did it's thing (and told us we could taxi as we
pleased, even during most of the ADHRS alignment), while a simple
fuel selector system (either select the left or right tank, or turn
them off) allowed us to select the fullest tank as we prepared to
head out of Gilbert Field.
The PFD kept us to date on the status of the avionics (and their
readiness for flight) as we headed out to Gilbert Field's Runway 4
on a fairly warm day (nearly 90 degrees). A little power gets
things moving quickly, while differential braking does steering
honors. The SR22 has a very tight turning radius (think of the
free-castering nose as a taildragger in reverse...) when the
situation warrants, though the wide gear geometry fights upset and
over-reaction. It also responds a bit lighter and more aggressively
than I expected with the heavy 550 taking up residence on the front
porch.
There is very little nosewheel strut compression in heavy
braking and surprisingly little sway in tight turns-despite the
considerable mass inertia involved in aggressive maneuvering.
Braking action is good, ground viz is also fairly good and in the
heat, the doors needed to be cracked a bit to keep things from
getting too toasty… there is way too much glass in the G2 to
avoid roasting on a warm day. The promised advent of an Air
Conditioning system for future SR22s is gong to be a blessing (and
a VERY popular option).
Our flight was to be conducted with 60 gallons of fuel and about
450 pounds in the cabin (gear and all). The normal gross of a G2 is
3400 pounds, with a useful load of 1150… leaving us enough
room for at least another passenger… possibly two, if one
wasn't two heavy… If we'd tanked up to the 81 gallon limit,
however, we'd have had to limit ourselves to just one more
soul.
The Entegra got it's act together well before we got to the
active runway so there were no excuses left… with half flaps
deployed for take-off, pitch trim rolled back to a
proper configuration, a light to moderate crosswind from the
right and 91 degrees boiling off Runway 4. I firewalled the
IO-550, tapped the brakes lightly to keep things lined up and was
rewarded with excellent acceleration and a swift liftoff. The
process is aided slightly with enough pitch persuasion to
break ground, and lessened just a bit, immediately thereafter to
prevent over-rotation. This took all of 800 feet… well under
what I'd expected from the conditions involved. SR22s are not
bashful about playing in the air… and get there quickly.
Climb Me To The Moon…
Initial climb capabilities allowed the G2 to brag about
1200-1500 fpm climb rates at 100 knots… speed that allowed
the IO-550 to cool very well and offered pretty good visibility in
a piece of airspace known to have way too many targets for
potential conflict the area just south of the Orlando Class B has
become quite the VFR shooting gallery of late). Through 5500 feet
(and even in other climbs in older SR22s), the bird demonstrates an
unerring ability to stay well on the good side of 1000 fpm though
10,000 feet or so, unless REALLY loaded down. Our climbs to 5500
feet averaged a solid 1170-1290 fpm throughout the profile. Every
flight I've made in any variant of the SR22 has been able to beat
the "book" climb rates quoted by CD.
I truly appreciate the way that Cirrus worked on the cockpit
visibility in this airplane. The windshield is far enough aft to
not screw up one's peripheral visibility too badly (one of my few
complaints with the Lancair Columbia… the windshield frame
terminates in an area that restricts lateral vision in what I
consider to be an important area). Visibility over the nose is
fairly good, though in an obstacle clearance climb, one will need
to relent on pitch now and then, to see ahead… but no worse
than anything else in this category. In cruise and approach modes,
the window-gifted Cirrus has few peers in overall
visibility… it's damned good.
A word here about the Cirrus side-stick. It's a pretty unique
construct in that the pitch attitude is motivated via a push-pull
slide arrangement that moves fore and aft rather than bending (at
the base) forward and backward. I love side-sticks… it's my
preferred mode of flight control and the long-term comfort factor
is impossible to argue with (albeit only with side-stick assemblies
designed with some sense of real ergonomics). There's a lot to like
in the Cirrus arrangement… a system that lends itself well
to long cross country and approach modes… though I tend to
prefer a side-stick that uses a pivoting base/pitch actuation mode
for hard maneuvering… while the sliding arrangement seems
perfect for long cross-country adjustments and approach-mode
corrections.
There is a thumb actuated trim button on the top of the stick
that works well in lateral correction (noting that roll and yaw are
mechanically interlinked and mixed to a slight degree) but I do
find the pitch trim to be a bit sensitive. It's easy to get used
to… but the fine tuning that may be needed during a series
of rapid-fire approach descents are going to be heard to nail down
until one gets REALLY used to the rate. I'd love to see a way for
flyers to adjust the rate to suit their needs. That would be a
great option to have (hint, hint).
