The Utility Myth

Not a winter goes by without someone sending me an e-mail that includes the sentence, “You aren’t really suggesting I don’t fly my airplane in IMC in the winter?” It’s usually from the pilot of a very capable piston single or light twin that is not certificated for flight in icing conditions; often the pilot includes something like, “I live in the Great Lakes and we get icing a large part of the year.” Sometimes I get a similar question about passenger and baggage loads. “The engineers at [insert airplane manufacturer name here] wouldn’t have designed the airplane with six seats if it couldn’t carry six adults, or at least four adults and two kids. Do you really mean I can’t fill the seats and the fuel tanks?” A current trend is questions about synthetic vision systems in glass cockpit panels or cutting-edge heads-up displays. “With an essentially VFR depiction of the runway, I can make a zero-zero takeoff and even a zero-zero landing ‘if I have to’, can’t I?”

Key Takeaways:

• The article challenges the "Myth of Utility" in general aviation, where pilots dangerously assume their aircraft can simultaneously achieve all maximum capabilities (e.g., full load, range, all-weather flight) due to marketing, economics, and ego.
• This misconception leads pilots to operate outside certified limits, such as flying into icing conditions without proper certification or attempting landings below minimums using synthetic vision, significantly increasing accident risk.
• Safe flying demands acknowledging inherent trade-offs; pilots must prioritize a specific utility for each flight and strictly adhere to the aircraft's certified limitations rather than marketing hype or personal desires.
