Scale models can be entered for this competition, with 2 elements to it:
- Static, where your model is judged according to members' opinions on the merits of its appearance, and how well it conforms to a scale version of the full size it emulates; and
- Flying, where your model should execute a number of manoeuvres according to the flying schedule.
Scale Flying Schedule
- Take Off (Take-off in a scale-like manner appropriate to the aircraft being flown, take-off is completed after the model has turned 90° at an appropriate height)
- Rectangular Circuit, ( At constant height with 90° corners )
- Figure of EightCrossover to be centred on the Pilot and away from the flight line)
- Procedure Turn (P Turn) (The model approaches in straight and level flight parallel to the flight line, then makes a 90° turn in a direction away from the flight line. This is followed by a 270° turn in the opposite direction)
- Chandelle (From a straight and level flight the model passes the pilot and then performs a 180 degree constant rate climbing turn in a direction away from the flight line, resuming straight and level flight in the opposite direction.)
- Optional Manoeuvre
- Optional Manoeuvre
- Optional Manoeuvre
- Overshoot or Go-around (The aim of the manoeuvre is to simulate an aborted landing due to a higher than normal landing approach.)
- Approach and Landing (From normal level flight, the model smoothly descends while throttling back and begins the approach with flaps and gear down, when applicable, and touches down with no bouncing and rolls to a stop.)
Manoeuvres 6, 7 and 8 are optional and may be selected from the following list:-
Optional Manoeuvres :-
Wing Over (Starting from straight and level flight and parallel to the flight line, after passing the pilot’s position a smooth climbing turn is commenced away from the flight line. At the apex of the turn the model then continues on a mirror image of the entry flight path and recovers to straight and level flight but in the opposite direction.
Loop (Entry and exit height to be the same. The throttle may be reduced at the top of the loop)
Split-S or Reversal (From Height and straight and level flight, the model performs a half roll and when inverted performs half of a circular inside loop and resumes straight and level flight on a flight path opposite to that of the entry.)
Roll ( Straight and level flight, and after one complete rotation, resume straight and level flight at the same altitude)
Roll of the Top ( Immelmann Turn) (From straight and level flight the model pulls up into the first half of a circular loop and when inverted, performs a half roll before resuming straight and level flight on the opposite track.)
Derry Turn (The model approaches at a high speed in straight and level flight on a line parallel with the flight line. The model then makes a steep one quarter circle turn in a direction away from the flight line, without losing height. When centred in front of the pilot the model makes a half roll in the same rolling direction as the entry, again directly followed by a steep one quarter circle turn in the opposite direction, and then flies off straight and level on a line parallel with that of the entry.)
Spin (3Turn) (From straight and level flight, the model decelerates into a stall and commences the spin through three turns and recovers to level flight on the same track as the initial flight direction. During descent the model may drift with the wind.)
Half or Reverse Cuban (Half Cuban Eight –The model pulls up into a circular inside loop until 45° nose down, then with a half roll, the model pulls out level at the entry height. Reversed Half Cuban Eight - Start with the 45° climb and half roll then downward loop to finish level with entry)
Stall Turn (The model aircraft starts in level flight, pulls up to a vertical flight path until it comes to a stop. At which point the model yaws through 180 degrees in a direction away from the flightline, then dives and finally recovers straight and level on a flight path in the opposite direction to the entry. Entry and exit should be at the same height.)
Extend & Retract Landing Gear or Flaps (The model approaches the landing area in straight and level flight and extends the landing gear or flaps. When in front of the flightline the model then executes a 360° turn in a direction away from the flightline. After the turn and when again directly in front of the flightline, retract the landing gear or flaps and the model then climbs away in straight flight.)
Side Slip (The purpose of this manoeuvre is to demonstrate a marked loss of height on final approach without the use of flaps, whilst maintaining the final approach track and avoiding an excessive build up of speed.)
