What is the managed speed when EXP CLB is selected?

When EXP CLB is selected on the Airbus A320, the managed speed that the aircraft aims to maintain during the climb is represented by the green dot (GRN DOT). This speed is known as the best climb speed, allowing the aircraft to optimize its climb performance while conserving fuel efficiency. The green dot is a speed that provides the best climb rate while still being within safe operational limits during the climb phase.

This speed management feature allows pilots to take advantage of the aircraft's performance capabilities without having to manually adjust and monitor the speed for various flight phases. Utilizing the managed speed through the flight management system simplifies the flying task and is aligned with the principles of efficient flight operations.

In contrast to other options, such as ECON CLB, 250 knots, or .78 Mach, these speeds may not be optimal for climb and serve different operational purposes during various phases of flight.
