• Mass, length, and other parameters of the design must be within the specified range.

• Participants have the freedom to select the airfoil used for wings and rudder, span and area of the wings, etc.

• The design should be stable and efficient and must have directional stability.

• The design should have the specified value of static margin.

• Participants must use only one type of software, XFLR5 (Foilsim III / AirShaper / Piano.Aero), for the purpose of simulation.

• The decision of the event manager will be final.

JUDGING CRITERIA:

• In the abstract round, the top 20 participants whose abstract models are complete and deemed good enough by the judges will be selected for the next round.

• The simulation round winners are decided by the design’s parameters like static margin, the position of CoG chosen, directional stability, efficiency, CL/CD value, and how close are the parameter values to the actual value as prescribed in the problem statement.

• In case of a tie, the time for submission will be considered to determine the winner, which means the participant who submitted first among the tied ones will be the winner.
