Instrument Failures In IFR: Aviate, Navigate, Communicate

Navigating through Instrument Meteorological Conditions (IMC) requires the use of electronic instruments and avionics. However, these instruments are prone to malfunctions and failures, which can be challenging to deal with, especially in IMC. In this article, we will discuss some tips on how to deal with IFR electronic failures and how to deal with them in IMC.

1. Stay calm: The first and most important step is to remain calm. A calm demeanor will help you think clearly and make rational decisions.

2. Identify the malfunction: Identify which electronic instrument is malfunctioning and assess the severity of the problem. Sometimes, an instrument may give a false reading or appear to be malfunctioning when it's not. Verify the problem before taking any action.

3. Use backup instruments: Most aircraft are equipped with backup instruments that can be used in the event of an electronic instrument failure. Familiarize yourself with these backup instruments before you need to rely on them in an emergency.

4. Trust your training: When an electronic instrument fails, trust your training and stick to standard operating procedures. Your training should have included emergency procedures to follow in the event of electronic failures.

5. Communicate with Air Traffic Control: If the electronic failure affects your ability to communicate with Air Traffic Control (ATC), let them know as soon as possible. ATC may be able to provide assistance and guide you through the airspace.

6. Use alternate navigation techniques: If your electronic navigation instruments fail, use alternate navigation techniques such as pilotage, dead reckoning, or using VORs to navigate. Remember to adjust your flight plan and make the necessary calculations.

7. Consider diverting: If the electronic failure cannot be resolved or is too severe to continue the flight safely, consider diverting to a nearby airport. Make sure to communicate with ATC and follow standard procedures for diverting.

8. Practice good cockpit resource management: Use all available resources, such as charts, checklists, and manuals, to assist you in dealing with the electronic failure. If you have a co-pilot, delegate tasks to them and work as a team.

In conclusion, dealing with electronic failures in IMC requires a calm demeanor, identification of the malfunction, use of backup instruments, trusting your training and standard operating procedures, communication with ATC, using alternate navigation techniques, considering diverting, and practicing good cockpit resource management. By being prepared and knowing how to respond to electronic failures, pilots can safely navigate through IMC and ensure the safety of themselves and their passengers.
