The objective of Bell’s SIO demonstration was to execute a Beyond Visual Line-of-Sight (BVLOS) mission in an urban environment transitioning into and out of Class B airspace representing future commercial flights. Mission results will be used to evaluate and demonstrate Detect and Avoid (DAA) and Command and Control (C2) technologies for use in future certified operations in controlled and uncontrolled airspace. Data collected during the demonstration will be used to support future standards development and Federal Aviation Administration (FAA) certification guidelines.
Launching from Bell’s Floyd Carlson field in Fort Worth, TX, the APT 70 flew a pre-programmed 10-mile circuit path along the Trinity River. Once armed from the ground control station, the APT 70 initiated a vertical take-off. The vehicle then rotated to fly on its wings where it became nearly silent to the ground below. The vehicle executed its mission profile at an altitude of 500 feet above ground level. The route included a road crossing and transition in and out of Class B airspace.
Communication between the ground station and the aircraft was maintained through a redundant datalink. A prototype airborne detect and avoid system, along with visual observers, provided the remote pilot with awareness of air traffic in the vicinity and recommended flight manoeuvres.
Bell’s technology partners for the demonstration include Xwing and the University of Massachusetts Amherst’s Center for Collaborative Adaptive Sensing of the Atmosphere (CASA). Integrated onto the APT 70 is Xwing’s airborne, multi-sensing detect and avoid system. Xwing’s system comprises of radars, ADS-B, visual system and onboard processing to provide aircraft tracks and pilot alerts transmitted to the ground station. The APT 70 also includes CASA’s intuitive, integrated display to provide pilots with local weather risk awareness and route-based weather alerts issued by their City Warn Hazard Notification System deployed in the DFW metroplex.
It is envisioned that in the future, an operational APT 70 could provide efficient, rapid and dependable transport for payloads up to 70lbs. The APT 70 is estimated to move three times as fast as ground transportation. The vehicle is capable of autonomous flight, automatically flying a programmed flight route and handling an array of contingency functions. Potential uses for the APT 70 include medical deliveries, third-party logistics, offshore delivery, and humanitarian relief.
