[NSRCA-discussion] P-21.14 Comet question for the experts

[Don Ramsey]

Looks to me like the entry and exit altitude are certainly not the same.  That has nothing to do with line length.  If the Subcommittee has said the lengths need to be the same that is the way it will be judged at the WC.  Might as well do it as they specify.

This is the challenge of interpreting and applying consistent judging standards. 

 

According to 5B.2 and  5B.10: 

In general, turn-around manoeuvres are positioning manoeuvres. Therefore, entry and exit altitude need not be the same if the pilot wishes to make an attitude adjustment. The keywords are  'in general', this implies 5B.2 and 5B.10 would be in effect unless otherwise specified in the manoeuvre description. 

 

P-21.14 description: 
Comet with consecutive two ¼ rolls in opposite directions, ½ roll.  From upright, push through a 1/8 loop into a 45° downline, perform consecutively two ¼ rolls in opposite directions, pull through a ¾ loop into a 45° downline, perform a ½ roll, pull through a 1/8 loop, exit upright. 

 

In the description of  P-21.14 there is no requirement mentioned to line length or how the lines are drawn except they are 45 degrees. Therefore I surmise the standard under 5B.2 and 5B.10 should be applied.

No they don’t. It’s a turn around maneuver that can be used for height adjustment. The power point specifically addresses this question in the downgrades.

This may have been asked already, but do the lines have to be the same length? 

 

Thanks,
