As technology advances so do opportunities. The global use of drones is ever-growing, however commercial and civil-use drones do not yet play the important role they should. The notion that autonomous aircraft are restricted, via cost and law, to government and military uses is vastly diminishing, and civil drones have become the next frontier.
Imagine sending a vital piece of hardware from your distribution center directly to your manufacturing facility across town in 15 minutes without a truck driver. Or flying in life-saving medicine and vaccines to remote areas of the world without needing any highway infrastructure.
Other civil drone systems have had marginal success, but not with the bandwidth we intend to use. This project will create a new standard of parcel delivery, humanitarian missions, and health care capabilities for improved quality of life for everyone.
Imagine we have the capability to deliver desperately needed medical supplies, such as urgently needed drugs, lab samples, or banked human blood from one hospital to another.
These goods could be placed into a shipping container. A specialized payload transport UAS (3DR Solo), that is to be modified in this challenge, could pick up the container and autonomously travel to and deliver the container to a hospital, laboratory, disaster response area, or a designated landing are for a disaster response or humanitarian aid in developing nations.

4.5. FLIGHT MISSION REQUIREMENTS
4.5.1 The flight Mission evaluates the teams’ ability to conduct a mission operation with their vehicle. This is the culminating event and a scored element of the competition.
4.5.2 A lead judge will be assigned to each team at the flight line. It is important that all team members follow the instructions of the judges. There will be additional judges assigned who are focused on different aspects of the competition (imagery, autonomy, safety, teamwork, etc.) depending on which tasks the team is planning to accomplish.
4.5.3 Only systems presented in the FRR, inspected by safety inspectors, and included in the preflight brief will be permitted to fly.
4.5.4 OPERATIONAL TIMELINE
4.5.4.1 Setup Time = 15 minutes maximum. Setup time begins when the team arrives at the flight line. A lead judge will be assigned to each team and will start a dedicated stopwatch after communicating with the team Captain. After the maximum time, the judge may declare mission start, regardless of the team’s readiness to launch the mission.
4.5.4.2 Flying Time = 30 minutes maximum.
4.5.4.2.1 Flying Time shall start at the declaration by the Lead Judge who will have a dedicated Mission Clock Stopwatch.
4.5.4.2.2 A team may elect to cycle through the takeoff and landing sequence during the flying time more than once for a variety of valid reasons (change batteries, load payload, etc). No points will be lost, but flying time continues to be used.
4.5.4.2.3 Flying time stops when the vehicle has completed flight (landed, crashed, or terminated) and the team has turned off transmitters. The lead judge will confirm with the team captain that the flying time period has stopped and the post processing time period starts.
4.5.4.2.4 Teams that are still flying after 30 minutes will be assessed a penalty of one point for each minute over the 30 minute time limit.
4.5.4.2.5 Teams that are still flying after 40 minutes will be disqualified.
4.5.4.3 Post Processing Time = 20 minutes maximum.
4.5.4.3.1 Post Processing Time begins immediately after the flying time stops. This time is for data processing. No RF transmission shall be performed during Post Processing Time.
4.5.4.3.2 Post Processing time stops when the team captain hands in the scoring sheets, or when the maximum post processing time is exceeded.
4.5.5 MISSION LIMITATIONS
4.5.5.1 Mission Boundaries
4.5.5.1.1 During the entire mission, aircraft shall remain in controlled flight and within the no-fly- zone boundary. A specific no-fly-zone boundary definition will be provided to teams following their FRR. Any vehicle appearing uncontrolled or moving beyond the no-fly-zone boundary during autonomous flight will be subject to immediate manual override. Failure of manual override will result in flight termination.
4.5.5.1.2 Teams shall display their no-fly-zone (geofence boundary) prior to flight.
4.5.5.1.3 After takeoff and before landing, aircraft shall sustain flight at an altitude between 30 feet and 350 feet MSL for the duration of the mission. Flight below 30 feet or above 350 feet during autonomous flight shall require manual override. Failure of manual override will result in flight termination.
4.5.5.2 Takeoff
4.5.5.2.1 Takeoff shall take place within the designated takeoff/ landing area, shown on the competition map.
4.5.5.2.2 Takeoff under manual control with transition to autonomous flight will be permitted but does not count as an autonomous take off.
4.5.5.2.3 The first takeoff will be scored, regardless if it is manual or autonomous. Only autonomous takeoff attempts on the first takeoff will earn points.
4.5.5.3 Landing
4.5.5.3.1 landing shall take place within the designated takeoff/landing area shown on the competition map.
4.5.5.3.2 Landing under manual control is permitted.
4.5.5.2.3 The first landing will be scored, regardless if it is manual or autonomous. Only a successful autonomous landing during the first attempt will earn points.
