landings
Posted: Fri Feb 17, 2012 5:47 pm
Hi to all. Bill N. has my sympathy. I too can't three point land my Rebel. I
am slowly coming around to thinking that there is something with the
airplane( MY airplane not all Rebels!) that creates this situation. There
has to be, I have been making three point landings for a long time and with
the majority coming out just fine. As far as bobp.'s technique...you can't
argue with success, I suppose, but I am just speaking about the speed that
is indicated on a short final, what speeds you do around the pattern is
fairly irrelevant. I am using 60 mph on final and probably cross the fence
at that speed. If I try to three point, two things happen that are scary,
first the airplane floats(unacceptable on a 1300 foot strip!) for maybe a
distance of 200 to 300 feet of more. Next instead of settling like all my
other taildraggers, it does NOT settle. It stops flying and drops the
remaining inches, and it drops hard. I will try some baggage at different
weights and not at my strip, but somewhere with some more length. The
airspeed is also driving me to drink. In cruise it indicates 80-85 mph, but
the GPS indicates a no wind 105 plus mph. Of course! A low reading ASI! No,
because on take-off the airplane goes light at around 50 mph and starts to
really fly at 60 mph. That's in the ballpark. On final, in agreement with
bobp's comments, it won't fly below 60 mph without a hefty rate of sink.
Whatever bobp is doing airspeedwise and he can't be doing all that much
wrong having as many Rebelhours as he has, if he truly were crossing the
fence at 75 mph, he too would float forever. There has to be a point where
he reduces the speed on a very short final. He just won't tell us, how he
does that. Finally there must be a hundred variations among builders
regarding angles of attack, placement of pitots, other placement angles of
the wing and so on, so it is difficult comparing notes, you may be doing the
old apples and oranges comparison. I have two more comments, but I am doing
those in a seperate e.mail, they have nothing to do with landings. Geert
