AVIATE: when ever anything goes wrong or out of the ordinary the first priority is to always ensure the aircraft is doing what you intend it to do. If not then always take over manual control as flying the machine is the first step to resolving a problem or issue and ensuring overall safety.
NAVIGATE: once in control the second priority is to know which way and heading you're going to. Avoiding terrain for instance becomes very important if drifting down!
COMMUNICATE: this is where you let ATC and your crew into the loop so everyone can start doing their part in ensuring a safe return and landing.
Safe flying everyone,
Flightcopilot
