When diverting to an alternate airport during an emergency, what is the recommended action for pilots?

When diverting to an alternate airport during an emergency, applying rule-of-thumb computations and estimates is considered a recommended action for pilots. This approach allows pilots to quickly assess their fuel status, distance to the alternate airport, and time needed to get there, which is especially crucial during an emergency when rapid decision-making is necessary. Rule-of-thumb methods can provide a practical, quick way to estimate essential parameters without getting bogged down in complex calculations or technology that may be failing.

Using manual computations and estimates can enhance situational awareness and decision-making, leading to a more effective diversion process. This method also helps ensure that the pilot retains control over navigation, especially if onboard systems or navigational aids are compromised or unreliable.

In emergencies, focusing solely on radio navigation may not be ideal, as equipment could fail or be unavailable. Climbing to a higher altitude can provide better visibility, but situational assessments and calculations regarding fuel and distance are often more critical. Consulting the flight plan for alternate routes can be helpful, but in emergency scenarios, the ability to make quick and effective decisions based on the immediate situation typically takes precedence.
