What is the standard speed for lead during climbs?

The standard speed for lead during climbs is typically 220 knots indicated airspeed (KIAS). This speed is established based on various factors, including aircraft performance characteristics and safety margins during the climb phase of flight.

Maintaining 220 KIAS during climbs ensures that the aircraft is operating efficiently while providing adequate separation from other aircraft in controlled airspace. It also helps prevent exceeding the aircraft's maneuvering or stall speeds, which are critical to maintaining safe operations in the climb.

In contrast, speeds of 240 KIAS and 250 KIAS are generally associated with specific operational contexts, such as in high-density traffic areas or certain aircraft class regulations, and may be used in cruise or descent phases rather than climbs. A speed of 200 KIAS, while it may be suitable for some situations, might be too slow for efficient climb performance and could lead to other operational risks. Therefore, the standard of 220 KIAS strikes a balance between safety, efficiency, and adherence to air traffic control requirements during climbs.
