Safety Spotlight: Emergency Procedures

Vacuum Pump Failure

A vacuum pump failure is a “Jekyll and Hyde” situation: If it happens in visual meteorological conditions (VMC), it’s usually not a problem. In IMC, it’s an entirely different story. A pilot who doesn’t notice a vacuum failure quickly enough and/or doesn’t have good partial panel skills will quickly succumb to spatial disorientation. The results are usually fatal.

Electrical Failure

An electrical failure at night or in IMC is a serious emergency. Troubleshoot the obvious first. If the cockpit suddenly went dark, did you accidentally hit the master switch? If the ammeter is showing a discharge (or a zero reading on a load-type ammeter), the alternator may have tripped offline. Follow POH procedures for a reset. If the issue can’t be resolved, start reducing electrical load to the essentials: Drop back to one radio and minimal navigation gear, shut down unnecessary lights, and turn off anything else that’s drawing power. Stay in VMC if possible. If it’s IMC, declare an emergency and divert.

Airframe/Control Problems

Unlikely though it may be, if something goes wrong with the flight controls or the airframe, do whatever it takes to keep the airplane under control. If the problem is serious and you have a parachute (either for yourself or for the airplane), think about using it. Otherwise, the situation will likely call for equal measures of care, creativity, and good luck.

Real Pilot Story: Mayday at Mount McKinley

Suddenly, the aircraft became uncontrollable during the sightseeing flight of what was then called Mount McKinley. Learn how the pilot managed his passengers and the almost impossible task of flying his crippled aircraft to a safe landing.

Landing Gear Problems

This is probably the most common “non-emergency emergency.” Short of extraordinary circumstances, landing gear failures or malfunctions simply don’t rise to the level of an emergency. Gear-up landings usually cause only minor damage. The aircraft in this photo was repaired and flying again in a matter of weeks.

Weather

Weather-related problems are largely self-inflicted. Solid basic weather knowledge, coupled with good aeronautical decision making, will stop most weather emergencies before they get started. If you get into a weather-related emergency, the best course of action may be to land immediately—whether or not there’s an airport beneath you! The bottom line: You (and your passengers) will almost certainly walk away from a precautionary landing. The same can’t be said of a thunderstorm-related structural failure or a “graveyard spiral” resulting from VFR flight into IMC.

Declaring an Emergency

Let ATC know you have a problem so they can help you. Learn more in this short video clip excerpted from the IFR Insights: A Practical Approach online course.

An air traffic controller may be able to guide you to an airport or suitable landing spot. Learn more in this short video clip excerpted from the IFR Insights: A Practical Approach online course.
