On a Mission: Managing Ice
Aircraft utility can go down significantly in cold weather. Adverse weather is more common and tenacious than in warmer months, and along with the fog, low clouds and wind, there is often the threat of airframe ice. Yet we still want, and sometimes feel we need, to fly. How can we balance the possibility of airframe ice with the utility of our airplanes? How do the experts-those "on a mission" with their airplanes-predict, avoid and escape airframe ice? To answer these questions I spoke with professionals who slog through the weather every day (and night), flying high priority aeromedical, charter and air cargo in piston, turboprop and small jet aircraft.
Key Takeaways:
- Pilots should prioritize avoiding icing conditions, even with "known-ice" certified aircraft, and have an immediate escape plan (climb, descend, turn, or land) to implement if ice is encountered, rather than enduring it.
- Effective ice avoidance relies heavily on current Pilot Reports (Pireps) and a thorough understanding of weather systems, as general forecasts can be less reliable; strict adherence to aircraft manufacturer's limitations is also critical.
- Avoid specific high-risk scenarios such as long vectors, procedure turns, circling approaches, and particularly any flight into freezing rain, as these prolong exposure or present extreme hazards.
