if one does not have a G meter, is there any other
way to do rolls and loops? Second, George says
don't do aerobatics with a passenger. Really? How
else can I show off my new skills?
|
G-meter: I personally would have one, but now my
butt is calibrated, I can tell the load factor without
looking. For aileron rolls it is only a (1 to 1.5) g
maneuver so it's not a big deal. However if you mess
up, split-s and let the speed build on pullout, it's nice
to know how many g's the airframe felt for
maintenance and inspection purpose. It's a personal
opinion and suggestion, and I think its a good idea.
Passengers
The original article was for pilots NEW to acro. Sure
after you are current and comfortable than by all
means. I am all about flying (safely) with-in limitations
and rules. If you have two chutes required(*) and are
under Van's aerobatic gross and with in the CG,
current and proficient, than by all means take a friend
up. Bring a barf bag.
I have flown 30 people, pilots of all kinds and non-pilots
doing RV acro demos. I have had a 16 year old girl w/
no pilot time, loop unassisted with some practice and
one demo and a little coaching.
(Warning: Don't give your controls over to anyone unless
you are darn sure they know what they are doing. I have
2000 hours time giving instruction. There have been
many accidents where a RV pilot gave the controls over
to the passenger and they broke the plane or flew into
the ground. As a CFI, I can do it legally. The FAR's
prohibit pilots from letting passengers fly. Consider
the stick as the wing removal lever. RV's especially the
TANDAM RV's get super light pitch forces on the stick
with passengers. You take a guy who does airshows,
in a T-6 and have him pull a loop in a RV, he could very
well over control. RV's have light controls which are a
joy but can hurt you if you pull too hard. I don't want
to spread fear and ignorance. The RV is a 6 g plane,
strong but not invincible. Just be careful w passengers.)
Sitting as a passenger doing ACRO and actually flying
ACRO are two things. Keep your acro short. One or two
loops and rolls, don't do a 20 minute airshow unless you
want chunks blown all over you. You do build G tolerance
up. That's a known fact, and some people love roller
coasters and others don't.
Be sure to tell your passenger if they feel green to
speak up and say something and don't forget to look
at them for signs of stress, sweating, color, body
language (clenched fist). You don't want to scare
them.
*chutes dual req, RV4/6 built heavy have a hard
time being under acro gross with two adults and
chutes. Chutes are not that heavy but its a factor
and many RV's are built heavy. Fly within limits.
Some RV's are solo acro planes with two seats.

I have a 6 with an O-360 and fixed Sensenich and
it seems to snap just fine (Ive only done it solo).

Personal preference Larry. I had a hard time with
them on my RV4. The plane would not snap fully and
would actually start to fly before the plane came back
around and pulled some G's, becoming more of a roll
than a snap. A snap roll, once you snap as you know,
is a low G maneuver. Van has wrote about this a lot
and talked about getting RV's ready for IAC
sportsman aerobatics competition. You can snap but
just not well for this reason, as I understand it and
from my attempts, that's what I experienced.
Stall strips are recommended by Van. I never liked
snap rolls myself, so I don't worry about it, but that is
the story on the RV, the wing is just so good it does
not want to stay stalled. If you are getting good clean
snaps than cool. I did them in the mighty Aerobat
C152 and I could not get the recovery perfect either,
so you are on you own. However snap away, that is
cool. I am going to try them on my new RV7 and might
play with stall strips.
Great questions and good talk guys, Cheers George

I'm an old fighter pilot and former spin instructor in the T-37.
Consequently, I have little fear of aerobatics and/or spins, erect or
inverted. I do realize the RV is not a hard acro bird, and don't plan
anything other than gentlemen's aerobatics. However, all my
experience is (was) in jets and I've done very limited acro in a
conventional powered airplane.
My questions pertain to power management doing acro in an RV (or any
conventionally powered airplane for that matter.) What does one do
with engine power in a loop or split S? Any difference between fixed
and constant speed props? Should I be concerned about shock cooling
while doing acro? I'm really talking about planned power changes and
not emergency power reduction because the nose is buried and the
speed is approaching Vne.
Can anyone recommend a book regarding conventional aerobatics?

mike goulian and geza szurovy have two books out that are what you are probably looking for.
basic and advance aerobatics are the book names.
t-37 spin training was cool! I can close my eyes now and still to the BOLD FACE.

I remember the procedure well, but it’s not in my August 1964 version of the T-37B’s ATC Flight Crew Checklist. I think I remember that we would climb to 25,000 feet to do spins at Williams AFB. It took awhile to get there but it didn’t seem excessive on the way down.
