15 minutes into it, after a 3 or so vertical dives, 4 rolls, one upside down, and one loop I was done. Packed a bag, it did not smell or taste good. You guys who do it, hats off.
Flying wise, it was really strange. Easier and harder at the same time. Easier - the airplane in comparison to what I'm used to is so draggy, that it is insensitive to the power settings, attitude etc. Point it straight down, and you can fly it like this, the airspeed does not really build up that much (I'd be over VNE on mine in a couple of seconds!). Control sensitivity is actually less direct and less precise, with more stick actuation required than what I'm used to. The roll rate of course is quicker, and it is very enjoyable. But the rudder and yaw control.... this is where the most difference comes in. It is ridiculously twitchy in yaw, sensitive to the attitude and even slight pressure on the rudder sends the ball 3/4 off. It sure takes good practice to fly it "on the ball". The visibility from the front seat is perhaps 30% of a basic trainer.
Now, landing was very different for me again. I can imagine it takes time and good training to master it. I only watched in awe how the gentleman who owns the aircraft greased it in 3-point.
with no dihedral, spring gear and wider
cockpit and slightly different cowling.
Easy to fly acro in. Hard to land. Does
exactly what you tell it to do
Yes, I tell people on their first flight that
the only time the ball will be in the center
is when it's rapidly passing through from
one side to the other!
PS Ailerons are better on the S-2B, better
yet on the S-2C, and mindblowing on a monoplane.
It was a sunny 30 degree day, two guys in a bubble canopy, makes for an slightly uncomfortable setting. We went out to the practice area, and did a few stalls, (although Akoch pointed out correctly that they weren't full, deep stalls) with a vertical downline, an inverted safety check, a roll or three (Akoch did a couple), and then a loop. After that we did some straight and level. Akoch then did some steep turns.
Turns out that was enough for one day, on the way back to the airport, Akoch flying, I asked him to look at the ball to see if he was coordinated. Fatal mistake, having him look down at the bottom of the panel, when he was queasy, was the tipping point.
My impressions were that Akoch is a better pilot than me, his handling of the airplane was much better than me at a similar point in my experience, and that he wanted to have a deep understanding of what the airplane was doing, and capable of.
I hope that he does not give up on Acro, I think that next time he will not be as queasy because he knows what to expect, whether he goes up with me or someone else. Any encouragement (or stories of your experiences) that you guys/gals can offer would be appreciated.
They are demanding cross country machines for sure but like other characteristics of the type that tends to sharpen your skills.And I now know why the Pitts/Eagle is not a X-country airplane
You sound like you liked it, so keep doing it! It only gets better from here...
I hadn't thought of that in a while, now I'm getting the urge to get some acro training!
3) +ve G tolerance
4) -ve G tolerance
They really have nothing to do with each other, but
you need to learn about each of them (and increase
your tolerance for them) if you're going to do aerobatics.
Aerobatics looks pretty from the ground, but once
you get into flying a sequence (eg contest or airshow)
of maneuvers, one right after another, with the +ve
and -ve G building, physically it's a bit similar to getting
into a bar fight. Lots of adrenalin, and you're beat up
and nauseous afterwards.
All told, a rather odd hobby, really. Some more reading:
And it is really humbling to hear that the professional acro pilots experience nausea to some degree as well as the result of the show sequence. I'd be dead And they sure make it looks like it is nothing for them, for us sitting on the ground!
Nausea was problem for first few hours them gone forever thank god.
Definitely hard on the body. Its a sport for a teenage body and a middle age wallet!
Did you make that up, Peter? That's pretty funny.Its a sport for a teenage body and a middle age wallet!
I don't have any problem with any of the above 4
human factors - as PIC - even if I've been off
a while. Positive G is easy - just remember to grunt
before the G goes on. With negative G, NO GRUNT!
You must totally relax, which is hard at first.
The story is completely different as a passenger. I
am sure that if I rode along in say Rob Holland's MX2
I would barf in 2 minutes. Like being a passenger
on the back of a 300 kph sportbike, it would be a
terrifying and nauseating experience.
When you are PIC, though, it doesn't seem that bad.
I remember riding in the back of an L39, daydreaming
and looking outside and THERE'S +8 G's from the
cowboy in the front seat. No G suit, and no warning of
the G coming on, either, so you grunt like a sonofabitch
trying to keep what little blood is still in your brain.
Holy crap, that's a long time. An ideal acro flight for meLasted about 45 minutes before I'd had enough
is 0.3 on the tach - after that, I'm tired and sweaty and
time for a shower and a nap. I know, it's not a good way
to build four-bars hours, but it's an awful lot of fun.
The best aerobatic pilots in the world - of which I am
surely not one of - only fly 40 hours of training per
year. That doesn't sound like much, does it? Not to
a four-bars, anyways. But that's actually 120 x 20
minute Unlimited category flights, directly overhead
Some of that was transit time ... I think the 45 minutes was when I said "enough" so it included transit to the practice area, and the acro ... maybe there was 30-35 minutes of actual manoeuvering.
And yeah, in chatting with him, I suggested and he confirmed that as a pilot it's a lot easier to handle. He said that early on when the instructor would show manoeuvres, he'd get queasy, but had no problem doing them himself.
I think we did -1/+5 on that flight ... maybe a little more.
I'm on blood thinners, I checked with the medical examiner to see if pulling G's might be ill advised, he said there shouldn't be any problem.
Not sure the same would be true as a regular acro flyer ... if even the smallest blood vessel bursts, it's 10 times worst for me. not sure whether blood vessels bursting actually can happen from high G's though, that's just my theory. something I'd have to keep in mind if I felt like flying acro more regularly.
I think negative G would be especially harmful because a burst blood vessel in the eye or brain would be catastrophic, and that does happen. Ive seen red eye a few times etc. Positive G is less a problem but you may be more susceptible to "Gseales".. This is when your lower legs get covered in small zits like measeles.
I think you need to talk to an experienced aviation doctor because I don't think the advice you got is accurate ( at least based on my small sample size of 2 70 year olds).
I have a lot of experience with Gs, typically every few days Im going +6 to -4 dozens of times and its not something to take lightly.
Please be careful!
Don't ever fly negative G, then. You're reallyif even the smallest blood vessel bursts, it's 10 times worst for me
going to screw yourself up.
As Peter mentioned, I have blown blood vessels
even where my lap and shoulder straps contact.
Not sure if it's from positive or negative G.
I would hope that you would be ok with positive
G as long as you don't have any other problems.
I might recommend that you fly 0/+5 G max
until you learn what works for you.
Medical examiners know nothing about either
positive and especially negative G's.
Not sure he'd give the same advice if I tried to do this as a PIC ...
Good point on the negative G's ...
