As a footnote though Richard, the 100 kilos or 220 pounds in the rear
cockpit was with the Russian ADF and flight recorder still in the
airplane.

It is also worth adding that the MAXIMUM that the Russians will allow
in the rear cockpit of a 52 is 100 kilos [220 pounds] and that includes
parachute;clothing;any cushions etc.I suspect that in the land of the
Big Mac,there are a number of pilots/passengers in the rear cockpit who
are well over this!!!

| Subject: | Re: Yak-52 Weight and Balance |
Using the W&B that came with my plane and the one Cliff attached to this
email string my plane is not within limits for solo acro, it is nose heavy.
Numerous people have told me this would not create a problem as it just
means the plane would be less likely to spin or at least easier to recover
from a spin. If this is true why would that area of the chart not include
acro? My own experience has not shown any problems entering or recovering
from normal, upright spins which is all I have attempted. Am I asking for
trouble?

Good afternoon Tom,
There should be a record of the weighing (or weight change) in the log
books.
I've attached a copy of the Excel sheet I've developed.
It's a little easier to use than the printed sheet you have.
If there's a question as to my derivation of these numbers, contact me off
list.
Hope this helps!
Cliff

Thanks Richard. I echo your sentiments about getting the proper training from
the right people. The question was an academic one.
Continuing that, (Dennis chime in if you know), Would anyone happen to know the
CG of the aircraft tested?

If you are forward of the C of G limit in a 52,I assume that there have
been changes to the plane -probably removal of the equipment behind the
rear seat.
The plane will be more reluctant to spin,and indeed recover more
easily,BUT,by definition will not be such a nice plane with which to fly
aerobatics,in that it will be more stable and will not want to pitch
etc.

If you're referring to the "Spins Unspun" article, the test aircraft,
according to the article, had a CG of 18% MAC, which is clearly a
forward CG. As I remember, without digging into additional
documentation, the design CG range for the Yak 52 is 19-25% MAC.

This is a great HUD film of an F-16 deadstick landing. Listen to the
coordination of his Flight to help bring him (#4) in safely. We should
always have a flight lead or two to help us out!
Happy New Year and fly safely!

Oops, sorry Dennis, I meant the article from quite a few years ago (saw the 18%
reference in "Spins Unspun".
