[NSRCA-discussion] Height of manuevers

[Bob Kane]

The "top" of the box is 60 degrees from horizontal, so if the AMA recommends flying 150 to 175 meters out, and we consider this the short leg of our triangle, with a little trig we can calculate the hypotenuse (line of sight from the pilot to the top of the box) to be 260 to 303 meters, and the height above ground level will be 225 to 262 meters or 730 to 853 feet.

Sort of blows the 400 ft AMA “limit” out of the water.   700 -
900’ AGL seems pretty normal on my Eagletree altimeter.

Has anyone done any testing using a altimeter of sorts such
as Eagletree's altimeter option to figure out exactly how high some of our
maneuvers end up?  In using basic Trigonometry I can estimate that if a
plane is flown at 150 meters at a 60 degree angle then the plane should be
around 260m (around 800') high... do we fly higher than this?  Obviously
the further out one flies then the higher one gets if at 60 degrees. 



   





Are there any true measurements that one could relay to
me... or if someone has an altimeter, could you test it out and let me know
please?  I'm particularly interested in current sequences/maneuvers...
especially F3A or Masters.  I don't think the lower classes get to an
altitude that is of any significance (generally speaking of course).
