What is the maximum crosswind for engine start?

The maximum crosswind for engine start is crucial for ensuring safe operations, particularly during ground handling of the Falcon 7X. A value of 25 knots indicates a well-considered balance between operational requirements and safety precautions.

In this context, starting engines in a crosswind that exceeds this limit could pose risks such as inadequate control of the aircraft during the start process, the possibility of the aircraft being pushed by the wind toward a nearby object or obstacle, and challenges for ground crew who may be managing procedures nearby.

The limit is set based on extensive testing and safety assessments that take into account the aircraft’s design characteristics, engine performance, and environmental conditions. This ensures that pilots and ground personnel have a clear boundary to follow which reduces the likelihood of accidents during the engine start phase.

Lower wind limits, such as those indicated in the other options, would not account for the aircraft’s capabilities and might suggest a more conservative approach than necessary, while higher limits would pose risks outside of the established safety parameters. Understanding this maximum crosswind helps pilots and operators make informed decisions before performing engine starts.
