![]() This is not an accurate name because the airplane never stalls. This maneuver is sometimes called a hammerhead stall. Rolls on the downline require only aileron input if the plane is trimmed correctly. ![]() The pivot must be completed within ½ wingspan. Elevator and rudder are used to keep the nose pointing straight down. When the pivot is completed, the ailerons and rudder are neutralized. The pivot is stopped with opposite rudder when the nose points straight down. It is followed by right-forward stick (right aileron and forward elevator) to keep the plane from torquing off. When the plane has slowed enough, full rudder initiates the turnaround. During the vertical line up, some right aileron and right rudder is needed to maintain the vertical attitude because of the engine torque and p-factor. When the plane is vertical, the elevator back pressure is released completely. The quarter loop is flown just like the first part of a loop. This is a detailed explanation on how to properly execute a Loop to the IAC judging standard. Rudder is used to maintain a constant heading throughout figure and ailerons are used to maintain the orientation of the wings. The plane has to stay in one plane with the wings perpendicular to the flight path. Past the top, the back pressure is slowly increased again throughout the back part till horizontal flight. Once past the vertical, the back pressure on the elevator is slowly relaxed to float over to top of the loop to keep it round. The maneuver starts with a pull-up of about 3 to 4 G. ![]() To achieve this, the pilot must adjust for ever-changing speeds and G-loads, as well as wind drift. It has to be perfectly round, entry and exit have to be at the same altitude. This is one of the most basic maneuvers, but not easy to fly well. This is a detailed explanation on how to properly execute the Point Roll maneuver to the IAC Competition judging standards. With Gordon Penner, MCFI-Aerobatic and FAA Gold Seal CFI with Jeff Granger, Intermediate competitor in an Extra 300. A roll symbol that crosses the line specifies a full roll (first figure).Ī detailed explanation on how to properly execute a competition Slow Roll to the IAC judging standards. A roll symbol that starts at the line denotes a half roll (see description of the Immelman). A notation such as 2x4 denotes two points of a four-point roll. A number by itself ( 2, 4, or 8) means a full 360º roll with the specified number of hesitations. If no points are specified, rolling is done without hesitations. Two-, four-, and eight-point rolls are allowed. Hesitation or point rolls include stops at certain roll angles. This requires constantly changing rudder and elevator control inputs throughout the roll. The roll rate has to be constant and the flight path must continue in a straight line. Slow rolls are flown normally on a straight line (one exception is rolls flown at the top of a loop). After the roll is completed the nose is usually 20 - 30 degrees below the horizon. The controls are maintained in that position till the roll is completed. The elevator is then neutralized and the aileron fully deflected in the direction of the roll. The aileron roll is started by pulling the nose up to 20 - 30 degrees above the horizon. The aileron is fully deflected in the direction of the roll. The aileron and barrel rolls are not flown in aerobatic competitions.Īileron rolls are flown with the rudder and elevator in the neutral position during the roll. There are four basic types of rolls: Aileron Roll, Barrel Roll, Slow Roll, and Snap Roll. Gordon Penner, MCFI-Aerobatic and FAA Gold Seal CFI Each figure is assigned a score from 0 to 10, which is then multiplied by the K factor.Ī brief discussion of the Aresti Symbols by Higher K-values mean more difficult maneuvers. The K-values included with the competition figures give an indication of the difficulty of each of these maneuvers. Any deviation from the center results in a downgrading during a competition. Rolls on vertical lines and on 45° lines have to be centered on this line to score well. ![]() There are some figures where this does not apply completely. For instance the quarter loops going into and coming out of a hammerhead have to have the same radius. The looping portions in almost all figures have to have the same radius in all parts of a figure. increments up to 2 rotations can be added to the lines. Parts of loops connect these line segments. These describe straight flight in these directions. The elements used in these figures are horizontal, vertical and 45° lines.
