What does Method 1 refer to?

Method 1 specifically refers to a protocol that is utilized during the flight phases after the V1 decision speed, particularly during the climb phase to cruising altitude. This method is crucial for ensuring that pilots maintain optimal performance and safety in the aircraft's ascent. V1 is a critical airspeed during takeoff; once the aircraft has reached this speed, the pilot must continue the takeoff should an engine fail, thus transitioning into a climb phase.

In this context, Method 1 becomes essential as it outlines the procedures to be followed for regulating climb performance and navigation effectively, contributing to a successful transition from the ground to cruise altitude. Understanding this method helps in comprehending the protocols pilots use in different flight stages, particularly following V1, which is characterized by significant operational thresholds and decisions.
