Boom Supersonic has raised over $1 billion and flown a supersonic demonstrator - but engine certification, regulatory uncertainty, and airline order conversions remain unresolved.
VectorThe Garmin GFC 500 brings certified envelope protection and modern autopilot capability to legacy Cessnas, Pipers, and Beechcraft - here's whether the upgrade pencils out.
VectorTwo ADS-B-compliant aircraft can be invisible to each other due to America's dual-frequency mandate - understanding why matters most in mountain terrain.
VectorZeroAvia flew the world's largest hydrogen-electric aircraft in January 2023, exposing why batteries alone cannot decarbonize regional aviation - and what can.
VectorZeroAvia flew a hydrogen-electric Dornier 228 in January 2023, proving fuel cell propulsion can lift a 19-seat regional aircraft - a genuine systems milestone.
VectorElectra.aero is building a hybrid-electric blown lift aircraft capable of takeoffs under 300 feet, targeting rural communities with no viable regional air service.
VectorEve Air Mobility is the only eVTOL company building urban air traffic management software alongside its aircraft - and that may be its biggest edge.
VectorHermeus's Chimera engine combines turbojet and ramjet operation in a single system, targeting Mach 5 commercial flight by the mid-2030s after 70 years of failed attempts.
VectorThe 2002 Überlingen collision killed 71 people when one crew followed ATC over their TCAS resolution advisory - the case that redefined automation authority in commercial aviation training.
VectorThe HRRR is a 3-kilometer, hourly-updating weather model that gives pilots the most accurate short-range convective timing guidance currently available.
VectorNASA's X-59 QueSST aircraft is designed to prove that shaped sonic boom technology can produce sound quiet enough to overturn a 50-year FAA ban on overland supersonic flight.
VectorTIS-B fills your ADS-B In display with radar-derived traffic, but a 15-nautical-mile 'hockey puck' service volume and 12-second radar lag create gaps most pilots don't know exist.
VectorArcher Aviation's Midnight targets 45 dB at cruise altitude - the noise threshold that will determine whether electric air taxis can operate in cities.
VectorEGPWS ended controlled flight into terrain as commercial aviation's top killer - here's the engineering behind it and why GA still lags behind.
VectorJoby Aviation's six-rotor S4 - 200 mph cruise, 150-mile range, 45 dB overhead - is the most technically mature eVTOL nearing FAA type certification.
VectorReliable Robotics is retrofitting the Cessna 208 Caravan with autonomous flight technology, targeting cargo routes first - and their certification strategy may be the smartest in the industry.
VectorThe May 2024 G5 geomagnetic storm disrupted GPS, knocked out HF radio, and forced mass polar rerouting - and the sun is still near its peak.
VectorThe FAA's LADD program masks tail numbers from commercial tracking sites, but a $30 software-defined radio can receive the raw ADS-B signal regardless.
VectorHow Delta 191's 1985 microburst crash at DFW led to Terminal Doppler Weather Radar and eliminated fatal wind shear accidents in U.S. commercial aviation.
VectorGPS spoofing over active conflict zones is corrupting the ADS-B position data controllers rely on for separation, with over 2,000 interference events logged in a single week in early 2024.
