First of all, what is the figure number 6? Just a loop with a 90 degree exit? Second, how is figure 9 flown? Is it one full roll during the first 90 degree on the 180 degree circle followed by a half roll on the last 90 degree of the turn? Or shall the rolls be divided different on the circle? If there is a better place to ask such questions please let me know....

First 90 degrees of turn inside roll, inverted to inverted, followed by an outside roll to upright during the second 90 degrees of the 180 degree turn.

I have searched the rulebook but I can't find information on how such figures should be interpered. I also found the CIVA rulebook. I think it is a little more detailed when it comes to descriptions of valid line length etc.... Quote: I believe this is a 7/8 loop with a down 45. Ohh ofcourse... that makes more sense. It has nothing to do with heading change, I don't know why I interpered it like that.... Quote: First 90 degrees of turn inside roll, inverted to inverted, followed by an outside roll to upright during the second 90 degrees of the 180 degree turn. Okay... just to be sure... the rollrate in the first 90 degree of the turn (the inside inverted to inverted roll) will be twice as fast, as the last (outside) ½ roll? I mean the figure only needs ½ a roll to return to upright and that has to be devided on the last 90 degree of the turn right? I thought I had to think of it as a 1½ roll divided on a 180 degree turn - that would be hard do right. I hope my decriptions are understandable - english is not my native language :-) Quote: Subscribe to the exploder. I'll try that...

You have to fly one and a half rolls (1.5) while doing a 180° change of direction. Because any change in your yaw or rollrate while executing the rolling circle will mean a deduction of points, the rules are as follows: For each half roll, you have to make a change aof direction of 60° degrees. 1.5 rolls = 3x60° = 180° So your inital thoughts where right! Thats how it is flown, judged and scored. I won´t have access to the list in the next two weeks, so please contact me via email if you want to have more details.

The roll rate needs to be the same throughout. The figure is 1/2 of a 3-roll 360 degree turn. The first full roll is done in 120 degrees of turn, the 1/2 roll is done in 60 degrees of turn.

Actually with your explanation I see that it is written in the rulebook.... I have an additional question regarding sides. For instance figure 9 in the sequence. I understand that I have to roll right (on the vertical) to get back on track... but which side am I supposed to rotate towards in the stall turn?

Figure 9 can be flown in either direction, it doesn't matter, since in either case you exit in the direction where you came from. In figure 5, if you for instance have the wind from the right (form B), and you are flying towards the judges (as drawn on form B), you need to turn to the right. f you were flying away from the judges, you would have to turn to the left. I remember it by visualizing that I have to turn such that my head points into the box.. That will get me flying into the box after the hammerhead turn.

I was thinking number 5.... I understand that according to form B I need to turn right on the vertical up. But the Hammerhead-turn afterwards... is that a right or a left foot rotation?

Hammerheads can be either direction... pilot's choice. Of course, engine torque/p-factor may have something to do with it most pilots hammering left. ) Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         AirTalk.org Forum Index -> Aviation (Aerobatics) All times are GMT Page 1 of 1   Jump to: Select a forum Aviation----------------alt.aviationAviation safety EnhancementPlanes, gliders and flying in AustraliaAviation et pilotage (Français)rec.aviationAviation (Aerobatics)Hot air, gas balloons and airshipsHang-gliding, paragliding, foot-launched flightAircraft Design & BuildingInstrument Flight RulesAviation (Classifieds)Military AircraftNaval AviationAviation (Miscellaneous Topics)Owning AirplanesAviators (General Discussions)Aviation related productsAircraft RestorationHelicopters and rotary wing aircraftsFlight SimulationSailplanesAviation (Students)Light aircraftFlying related activities in the UK Airports----------------alt.airportsEdinburgh Airport Glasgow Airport Humberside Airport Luton Airport Aberdeen Airport Glasgow Prestwick Airport  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
