GPS touches many more systems than most pilots realize. How would a GPS-swaddled pilot do if that one bit of information was denied to every system on the aircraft?
Searching the Sky
Its all Chets fault. The whole thing had started over beers, with Brian regaling us with details of his latest foray down south in his Cirrus.
Key Takeaways:
- A simulated GPS denial scenario revealed that modern aircraft and pilots are profoundly reliant on GPS, affecting numerous systems beyond primary navigation, including traffic, terrain, weather, and essential data like DME and groundspeed.
- During the experiment, pilots faced significant challenges due to rusty traditional navigation skills, loss of critical situational awareness tools (like moving maps and winds aloft), and the unavailability of most RNAV approaches.
- Despite the extensive system failures, the pilots successfully navigated and executed a full-procedure ILS using conventional VOR/ILS methods, highlighting the critical importance of maintaining proficiency in traditional navigation techniques.
- The article underscores the vulnerability of GPS-dependent aviation systems to disruption and raises concerns about the preparedness of pilots trained exclusively on glass cockpits for potential GPS denial situations.
