SCHEMATIC MANEUVER DIAGRAMS AMA ADVANCED 403 Effective 2011 SCHEMATIC MANEUVER DIAGRAMS AMA ADVANCED 403 Effective 2011

– Takeoff (U) Reminders: It is not necessary for the model to stand still on the ground with the engine running without being held before the takeoff begins. It is also not necessary for the model to reach 2 meters in the same distance as the takeoff roll. The takeoff should not be downgraded for wing dips caused by air turbulence unless the wings are not immediately leveled. The lift off should be within two (2) meters of center for maximum points. The maneuver is complete when the model is approximately two (2) meters (6-1/2 feet) off the ground.. Downgrades: !Model jumps from the ground. !Retouches the ground after becoming airborne. !Steep climb angle. !Gallops in elevation during climb. !Model does not accelerate smoothly. !Model passes behind the judges line, scored zero (0) points.

The model may appear like it doesn’t perform 2 ½ turns. However, this is unavoidable due to near stall and preservation of track In strong wind, entry must be on center but exit may have drifted due to near stall during spins. This is also unavoidable in the proper execution of a near stalled maneuver

20 Landing area: the entire defined runway – Landing The landing will not be downgraded if: The model rolls to a controlled stop within 10 meters. Wing dips which are caused by air turbulence unless they are not immediately corrected. The pilot “slips to a landing” to handle a crosswind condition in which case a wing will be low Displacement of the touchdown point left or right as long as the landing is in the landing zone Landing begins when the model is approximately two (2) meters (6-1/2 feet) from the ground. Downgrades: !Model passes behind the judges line, zero (0) points. !Model impacts the runway due to lack of flare. !Model bounces. !Changes in track, 1/15 rule !Model ends on its back, zero (0) points. !Model lands outside landing zone (but still on runway). !If any undercarriage retracts or collapses before the landing is complete, zero (0) points. !Aircraft “porpoises” and/or wanders during approach or flare. !Aircraft lands outside the landing area or runway, zero (0) points. Landing zone is 30 m long and normally the width of the runway BUT not more than 30 M wide. Landing zone (white) and Landing area (green) shown below. Runway up to 30 m wide 30 m long Landing zone dimensions
