IFR Emergencies

There you are, droning along in the clag, watching the autopilot watch things for you, monitoring the frequency and marveling at how the IFR system’s various parts mesh together. But you haven’t been paying attention to the ammeter, which is showing a steep discharge. Suddenly, your autopilot’s control panel goes dark, along with your older number two nav/comm, and the stable airplane you’ve been monitoring—not flying—for the last hour and half wants to pitch up and bank right. Congratulations: You’re about 15 minutes from completely draining the ship’s battery and total electrical failure in IMC. You’re also about 20 minutes from the nearest suitable airport, one with services like a maintenance shop. Did we mention it’s well past sundown?

Key Takeaways:

  • Pilots flying in instrument meteorological conditions (IMC) must be prepared for various system failures, including electrical, vacuum, mechanical, and avionics issues.
  • The immediate priority in any emergency is to "fly the airplane," followed by managing the system failure through pre-planned procedures, shedding non-essential loads, and utilizing emergency authority.
  • Thorough knowledge of the aircraft's systems, emergency procedures, available backup equipment, and effective communication with Air Traffic Control (ATC) are crucial for making informed decisions and ensuring a safe resolution, such as diverting to a suitable airport.
