Planned GPS outages in southern California
From the article: &quot;Operators of Embraer Phenom 300 business jets are being urged to avoid the area entirely. “Due to GPS Interference impacts potentially affecting Embraer 300 aircraft flight stability controls, FAA recommends EMB Phenom pilots avoid the … testing area and closely monitor flight control systems,” the Notam reads.&quot;<p>That is beyond scary; how anyone can defend having critical aircraft control systems rely on an input which may be turned off at will is beyond me.<p>Let us at least hope the system fails gracefully and notifies the pilot that something odd just happened and you will have to do your own flying from this point on, rather than just going titsup and be done with it.
