[NSRCA-discussion] Masters 2007 Figure "M" question - verticalsegments

Wed Oct 18 03:41:28 AKDT 2006

Although not mentioned as a specific downgrade in that section why would a 
pilot choose to fly one  a shorter leg unless avoiding another plane in that 
area? Why give judges an opening to downgrade in any maneuver?

verticalsegments

Now that we're breaking this down, I'd like some clarification on the
section of the rule below that states:

"The length of the vertical segments is not a judging criteria."

In the strictest translation of this sentence I would say that this means
that the two stall turns do not need to be the same height, however, this
seems inconsistent will all other centered maneuvers where two halves of an
object do have to match in size.

A looser translation could be that the intention of this verbiage is to
point out that a shorter 'M' should score as well as a taller 'M', but
assumes that both sides should be the same height (which isn't stated
anywhere).

Unless otherwise clarified, I'd have to deduce that indeed the two stall
turns don't have to be the same height.

Below is the Figure M description from page 79-80 of the current AMA rule
book...Note the statement regarding rolls and stall turn direction are
pilot's option...I then found this statement "Edit page 79-80 Figure M with
¼ or ½ rolls" to include ¾ roll options" on the NSRCA page under:
http://nsrca.org/competition/judging/Patterns2007

Figure M with 1/4 or 1/2 Rolls: Model pulls up into one-quarter (1/4) loop
to a vertical track, hesitates then performs prescribed roll, hesitates then
executes a stall turn through 180 degrees, hesitates, performs
prescribed roll, hesitates then executes one-half (1/2) outside loop to
vertical track, hesitates, performs prescribed roll, hesitates, executes a
stall turn through 180 degrees, hesitates, performs prescribed roll,
hesitates then recovers with another one-quarter (1/4) loop to level flight.
Direction of rolls and stall turns are pilot's option. The length of the
vertical segments is not a judging criteria.

Downgrades:
1. Model not vertical at start and finish of rolls
and stall turns.
2. Stall turns not exactly 180 degrees.
3. Model does not execute prescribed rolls.
4. Rolls not centered in vertical lines.
5. Bottom of outside half loop not at same altitude
as entry and exit.

Regards,

Glen

Hi Jim,

Unless the maneuver has changed from 15 years ago all the rolls have
to be in the same direction, resulting in one stall turn being
canopy-facing you and the other being belly-facing you (your choice
as to which comes first).  It's a tough maneuver, especially when the
wind is blowing other than down the runway.
