When is it recommended to delay the first turn after takeoff?

Delaying the first turn after takeoff until reaching 400 feet AGL (Above Ground Level) is recommended to ensure that the aircraft has attained a safe altitude, allowing for greater control and a margin for error in case of any immediate issues. At this altitude, the aircraft is better positioned to maintain positive climb performance and to effectively respond to any engine failure or other emergencies that may occur shortly after takeoff.

This altitude provides the pilot with additional time to assess the aircraft's behavior and performance after takeoff, ensuring that climb is steady and the trajectory is stable before executing any turns. Conducting turns at a lower altitude, especially without adequate climb performance, could lead to spatial disorientation or loss of control.

In summary, turning at or above 400 feet AGL allows for enhanced safety margins and is consistent with recommended operational practices for commercial aviation, prioritizing altitude gain before maneuvering the aircraft.
