RE: IMAC maneuvers
You will learn that IMAC gives the pilot the freedom to present the entire sequence in any position relitive to the judges. Depending upon the sequence some are best started in front of the judges and others may lend themselves to beginning at one end of the field. In IMAC its up to the pilot to present the sequence of manuvers to the judges so that each manuver may be easily viewable and thus judged. This year the guys at IMAC did a great job putting the class knows together and they are easily presented. The ACS score is "Airspace Control Score" and is a 0 thru 10 score based upon how well you present the sequence to the judges. You will find all this information on the IMAC site. What class are you flying and where do you live? Tulsa is having its contest May 15th if you can make it.
Here is the info from the IMAC site.
"The following standard will be used for assessing the pilot’s performance in maintaining control and awareness of the aerobatic airspace and placing figures in the airspace in a manner that allow the figures to be optimally judged. vThe HIGHEST standard for Airspace control: vThe pilot that exhibits a significant ability to control the location of the aircraft inside the Airspace, relative to the Judges, resulting in a tight footprint and locates the aircraft that it can be optimally judged at all times should receive a TEN (10). v vThe LOWEST standard for Airspace control v vThe pilot that exhibits a poor ability to control the location of the aircraft inside the Airspace, relative to the Judges, resulting in an excessively large footprint and has the aircraft consistently so far away as to be difficult to properly judge. This pilot exhibits a very poor Airspace control and should receive a zero (0).
vPilots exhibiting Airspace control within the range of these two standards will be graded with a range of possible scores from ten (10) to zero (0) in whole point increments.
vK factor for the Airspace Control Scores for Sportsman class is 6K"
