Possible bug assigning K factors to knife edge flick rolls on looping segments about main HOT 3 CLOSED

OpenAero follows the rule as stated in the Aresti Catalog "Positive and negative flick rolls":
25. In the case of flick rolls initiated from knife-flight, the K-factor accorded
to the manoeuvre shall be determined by whether the flick is initiated
using top rudder or bottom rudder. When top rudder is used, the lower
coefficient shall apply, while the higher coefficient shall apply to flicks
initiated with bottom rudder.

If IAC rules deviate from this, OpenAero would need a specific determination algorithm for IAC flick roll K factor. The term "carefull consideration" in the IAC rules is rather vague. In any case, the wing loading before a knife edge flick roll is never positive or negative, it is always 0. A positive or negative wing loading in knife edge results in the aircraft changing course. The rudder position to maintain pitch is much more relevant, which is why the Aresti Catalogue rule is stated as it is. It is true that this position would be somewhat different in a loop, but this can vary dramatically between aircraft and power setting.

The best solution may be to change the IAC rules to conform to the Aresti Catalogue. In this aspect, it's interesting to note that this rule was added to the catalogue in 2009. Before this, there was no agreed-upon definition for knife-edge flick K factor. Could it be that the IAC rule is from before 2009, and no attention has been given to updating it?

I sent an email to the IAC rules chair asking for their interpretation. Further consultation with some of my colleagues at IMAC shows I may be wrong in how I am interpreting the table, and the current Openaero is probably correct. Hopefully I'll hear back from IAC. Will let you know. Thx

After discussion and consideration, i've altered my thinking on how I've been interpreting, and accept the way the program is making the K factor assignments. No issue. Closing the issue.
