Federal investigators are examining a deadly air ambulance crash in New Mexico, where the crew lost GPS navigation during a military jamming exercise. This incident raises questions about civilian aviation’s readiness for electronic warfare challenges.
Crash Details
The National Transportation Safety Board’s preliminary report indicates that the crew of a Beech King Air lost GPS capabilities minutes after leaving Roswell, New Mexico, on May 14. The U.S. military was conducting a scheduled GPS-denial exercise. Air traffic controllers requested suspensions of the jamming twice while aiding the flight, though it remains unclear if the interference was a factor in the crash.
The aircraft departed from Roswell near midnight, heading to Ruidoso, New Mexico, on a medical mission. Prior warnings from the Federal Aviation Administration (FAA) highlighted potential GPS disruptions due to the military exercise near White Sands Missile Range.
Investigation Findings
Shortly after takeoff, pilots reported losing GPS and sought help from controllers, who in turn asked the military to pause the exercise. Three other aircraft in the vicinity also reported GPS issues. The crew eventually spotted the airport and requested a visual landing approach. However, after the military resumed jamming, the aircraft descended and crashed into the Capitan Mountains, resulting in the loss of both pilots and two flight nurses.
Growing GPS Concerns
Aviation authorities globally warn of GPS interference as a rising hazard. The FAA advises pilots to fly without GPS as jamming concerns grow. The U.N.’s aviation body cautions that interference might impact aircraft far from conflict zones.
The agency’s 2026 guidance mentions a significant rise in GPS jamming incidents, highlighting a 65% increase in reported losses in the first half of 2024 compared to the previous year. Potential impacts include deviations from flight paths, position misreporting, and difficulties in transitioning to backup navigation.
Expert Opinions
Todd Humphreys, from the University of Texas’ Radionavigation Laboratory, questions civilian aircraft navigation technology’s resilience against jamming threats. He notes many FAA-certified GPS receivers use outdated technology.
According to Humphreys, contemporary GPS technology is more interference-resistant, but certification standards lag behind. He contends that the pilot’s smartphone likely contained a superior GPS receiver compared to the certified system in the aircraft.
Industry and Regulatory Responses
Military systems, unlike illegal consumer jammers, aim to block satellite navigation over vast areas for realistic training. In New Mexico, the FAA’s notice mentioned potential disruptions extending hundreds of miles.
Authorities in Europe and the Middle East face similar challenges, with routine GPS jamming and spoofing incidents linked to regional conflicts affecting aviation. European regulators have updated pilot guidance in response to these challenges.
Humphreys calls on the FAA to accelerate the modernization of aviation technology in response to these threats. He stresses the need for better systems and antennas to enhance flight safety.
Although GPS disruptions in the U.S. are mostly linked to military testing, the increasing prevalence of drones means counter-drone GPS jamming could become more widespread. Humphreys argues that regulatory actions need to keep pace with these evolving threats.
