Describe how a pilot can estimate a direct-to-destination course correction after discovering a lateral track error.

A useful approximate method is to separate the correction into a **drift angle** and a **closing angle**. Estimate drift as $60\times$ off-track distance divided by distance already flown; estimate closing angle as $60\times$ off-track distance divided by distance remaining. Turn toward the destination by roughly their sum, while monitoring the result and avoiding overcorrection.\n\n**Key takeaway:** Correct both the accumulated track error and the remaining distance to regain the destination.\n\n**Glossary:** **1:60 rule**: approximate relationship between angular error, distance, and lateral displacement.
