FAA GPS Interference Tests Put U.S. Business Aviation Crews on Alert Across Multiple Regions
Business aviation crews operating across several regions of the United States face scheduled GPS interference testing during September, creating an important flight-planning consideration for corporate, charter and private aircraft. FAA notices identify testing associated with several military installations and test ranges, with affected areas potentially extending well beyond the immediate locations where the testing originates.

GPS degradation can affect more than the cockpit moving map. Modern business aircraft integrate satellite positioning into navigation and multiple interconnected systems, meaning unexpected interference can create confusion if crews initially interpret degraded information as an onboard equipment problem. Operators should review current FAA notices and applicable NOTAMs immediately before departure because schedules and affected areas can change.

NVOII is highlighting the tests because GNSS reliability has become a growing operational issue for business aviation worldwide. Scheduled U.S. testing is fundamentally different from hostile jamming or spoofing seen in international hotspots, but crews still need to recognize degraded satellite navigation quickly, understand which systems may be affected and remain prepared to transition to appropriate alternative navigation procedures.
