Short Technical Report: This is the compact version of Technical Report., including abstract (1 pager) and two-column contents (8 pages). The format will be announced in the website. 3. Test Flight Video: The video must be able to demonstrate the take-off weight and the airworthiness of the aircraft. Some notes about the video are as follows: (1) The values of empty weight and take-off weight should be shown clearly in the video. The whole aircraft should be covered in the film when it is weighed. (2) The airfield traffic pattern should be completed twice at least. (3) The rolling distance of 60 m should be marked. (4) The video from weighing to landing should be shot in one take without cut. The film can not be spliced. 4. Exhibition: Before the flight operation, the aircrafts should be shown to the public in the specified place and time. The entrants can arrange their own exhibition space with posters, documents, multi-media, and so on, to provide an effective presentation of their works to the judges and visitors. The team will be interviewed by the judges in the exhibition. VI. Flight Mission 1. The flight mission has three rounds of cargo flight operations. In every round, the teams perform their cargo flight operations in the order determined in Leaders' Meeting. The actual take-off and payload weights will be reviewed and announced by the judges when the round has finished. 2. The flight operation region is composed of four areas: Preparation Area, Weighing Area, Start-Standby Area, and Runway Area. The entrants should obey the instructions of judges and assistant staffs to perform the specified operations in these areas. In the process of flight operations, only the judges, staffs, and the entrants with player cards are allowed to enter these areas. The operation region is controlled by

5 the judges. All the teams can not practice and test in the region without permission. 3. Process and requirements of a flight operation: (1) Pre-flight preparation: The entrants move the aircraft and corresponding equipments to Preparation Area when noticed by the assistant staff. The radio transmitter is retrieved from RF Control Officer at the same time. (2) Weighing: The aircraft is moved to Weighing Area as noticed by the assistant staff. Empty Weight is measured when no payload is equipped. Take-off Weight is measured after the aircraft is loaded. Since the weighing is finished, nothing is permitted to be removed from the aircraft. (3) Start: Following the guidance of the assistant staff, the entrants move the aircraft to Start-Standby Area. The entrants start to boot up the radio system and the motor in accordance with the judge s instruction. Timing begins at this moment. The time limit for start process is 10 minutes. When boot-up is complete, the motor is kept standby, and the entrants should inform the judge. If the time limit is exceeded and the aircraft can not boot up, the flight operation fails and the load score is not recorded in this round. (4) Take-off: When the aircraft boot up completely, it can be moved to Runway Area to take off. The direction of take-off is assigned by the judge. The nose of the aircraft should be aligned with the Start Line marked on the runway when it starts to roll and take off. The maximum rolling distance of take-off is 60 m. Any portion of the aircraft touch the ground behind 60m Line, the take-off is regarded as a failure. The success and failure of take-off is determined by the judge and announced in flags on the scene. There is a video camera placed at 60m Line to record the images as the aircraft passing. If the 10-minute limit is not exceeded since the start process, the aircraft can retry to take off again. If the aircraft can not take off successfully and the 10-minute limit is exceeded, the flight operation fails and the load score is not recorded in this round. (5) Flight: The airfield traffic pattern should be completed twice at least. The flight time, from off-the-ground to landing, should be 2 minutes at least. If the aircraft is off the ground but regarded as failure for rolling beyond 60m Line, it is permitted to carry through the flight operation, but the load score is not recorded in this round. (6) Landing: The aircraft must land inside Runway Area and in the direction assigned by the judge. The aircraft lands inside the runway, rolls and stops on its gears, or rolls for 5 seconds, it is regarded as a successful landing. Except the propeller and the landing gear, the main structure of the airframe should not be damaged. Whether the main structure is damaged is decided by the judges. After the aircraft has landed successfully, the following situations will not be regarded. 4. Loading requirements: (1) The maximum take-off weight must not be larger than 120% of the take-off weight shown in test flight video, and not be less than 80%. The range of take-off weight of every team is decided in Leaders' Meeting. (2) Empty Weight is defined as the weight of aircraft without fuel and payload, but the necessary part to maintain the ability of flight should be equipped, including

6 the radio device, battery, and counterweight. In principle, the aircraft should park on the ground normally with its own landing gear without external assistance. (3) Take-off Weight is defined as the weight of aircraft with fuel and payload. The required amount of fuel is 300 c.c. at least. More fuel is permitted but 600 c.c. is maximum. 5. Judges and Measurements (1) There are two judges in each runway at least, at Start Line and 60m Lind respectively. Assistant staffs are responsible for timing and photography. (2) The results of time, length, weight and volume in the competition is based on the measurements of equipments provided by the organizers. (3) If the entrants doubt the judgment of failure or success of take-off, they can request to review the recorded video and re-determine the take-off after the round of flight has been finished. (4) When the entrants have questions about the judgments, only the students have the right to appeal. The instructor and pilot can give a hand to illustrate the question, but can not make appeals instead. 6. Safety requirements (1) If the aircraft is unfinished, or decided to be not airworthy by the judges, it is not permitted to fly in the competition for safety. (2) The flight operations must be halted in consideration of the decay of daylight. If some teams have not finished their flights, the judges can extent the time of operations to completion of the round. (3) The aircraft can be repaired with the same parts and modules, but its configuration must be the same. The specification of engine can not change. If the configuration changes obviously due to repair or improvement, the aircraft should be reviewed and qualified for flight operation by the judges again (4) All the RC transmitters are handed over to RF Control Officer to prevent any possible radio interference in the competition. If the transmitter is need for tuning of the aircraft, it can be taken back when RF Control Officer confirms no frequency interference. (5) Safety barriers, such as nets or obstacles, will be set at 200 m from Start Line on the runway to protect the contestants and visitors from injures. The entrants have to think about the rolling distance of landing and make some precautions. (6) The airspace of a runway is restricted. Only one aircraft is permitted to fly in the airspace at one time, or collisions may occur. When an aircraft leaves its own airspace and intrude the others, the judge can ask the pilot to correct its flight path. If the pilot neglects the judge's warning and keep intruding other airspace, the judge can disqualify the team and ask the aircraft to landing immediately. The load score will not be recorded in this round. 7. Amendment of Rules (1) The flight operation will be governed by this rule. The rules for detailed implementations will be announced before the competition. (2) If the rule needs be amended before the competition, it must be agreed by all judges. (3) The amendment can be moved in Leader's Meeting and be passed if all judges and leaders agree with. (4) In the process of competition, if the judges think it is necessary to amend the rule, they can call Leader's Meeting to discuss the amendment. The rule can be amended when all judges and leaders agree with.

7 VII. Grading and Awards 1. Payload weight: The score is the summation of Maximum Take-off Weight and Maximum Load Ratio scores. The highest score is 40 points.
