[NSRCA-discussion] P19.15 - Double Key

[Derek Koopowitz]

Hey Jas,

 

Sorry about the delayed reply… I’ve been busy moving my mother-in-law the past 4 days – still not done yet.  To answer your questions… there are several ways to fly F-17.1 (triangle) correctly.  See below… all are valid.  Obviously, you need to ensure that your radii are all the same and that the lines up/down are 45 degrees and are the same length with rolls positioned in the middle of ALL lines.

 

 

As for F-17.10 (Figure 6 with stall turn), the entry radius will determine the size of your ¾ loop.  The length of the line up for the stall turn is your choice… there is nothing in the rule that states the line should be short/tall.  The roll down must be in the middle of the line – since it is a full roll I would suggest the line up be tall enough so that the roll down doesn’t look rushed and there are visible straight lines before and after the roll before you pull into the loop.

 

I hope this helps and be careful out there in Florida.

 

-Derek

Thank you Derek.

 

What about the F-17 Triangle and Stall Turn/6 while we're on the subject of maneuver variety.

 

Triangle: touching radio at beginning (like power point) or spaced apart radi?

Short stall turn, roll, low loop or tall stall turn, early roll and high loop?

Hi everyone,

 

Clarification on the Double Key has been received.  Based on the maneuver description, the maneuver doesn’t have to be flown as drawn in the aresti or the powerpoint (see below):

It can actually be flown in multiple ways (see below):

The revised powerpoint is below showing the alternate option:

Let me know if you have any questions…
