Beta Technologies refers to the six-seat Alia 250 as an "electric vertical aircraft," rather than using the standard industry term eVTOL.
As of mid-January 2019, when Beta Technologies first revealed the program to media, the Ava XC prototype had completed 176 test flights. At least another 50 more were completed that year before the company confirmed that the aircraft had only ever been intended as a technology demonstrator for the propulsion system it intended to deploy on a new eVTOL design.
This plan went semi-public on November 22, 2019, Beta founder Kyle Clark released some details about a new eVTOL model called the Alia to an invitation-only event called TexasUP held at Ross Perot Jr.'s ranch in Westlake, Texas. The design architecture of Alia is very different from Ava XC, with four fixed rotors installed above the fuselage and a pusher propeller in place of the Ava XC's eight propellers. Beta has indicated that the all-electric Alia will fly further than its sibling at up to around 250 miles. It has confirmed that the Alia prototype is being fitted with the new Foresight health and usage monitoring system developed specifically for eVTOL aircraft by Vermont-based GPMS.
In June 2020, when Beta unveiled the Alia prototype at its headquarters in Burlington, Vermont, it became clear that the new model has become the focus of the company's ambitions in the eVTOL sector, and that the Ava XC was in fact used as a technology demonstrator for various aspects of the planned propulsion system. The Alia has been selected by the U.S. Air Force to participate in its Agility Prime technology demonstrator program. Beta claims to have airworthiness approval for the Alia, but it has not published any timeline for type certification and service entry. Majority shareholder United Therapeutics has already committed to using the Alia for delivering organs for transplant and passenger-carrying air taxi flights have been identified as a potential role for the distinctive design. The Alia will offer 200 cubic feet of cargo space and will have room for six passengers.
Beta intends to conduct flight testing in Plattsburgh, New York, having ferried the Alia prototype across Lake Champlain carried by a Sikorksy S-61 helicopter on June 12, 2020.
