During a slow flight demonstration, what is the maximum allowable heading deviation?

In a slow flight demonstration, a maximum allowable heading deviation of ±10 degrees is considered appropriate to ensure proper performance and control of the aircraft during this critical flight maneuver. Slow flight is a fundamental flight training exercise where pilots learn to operate the aircraft at an airspeed just above stall speed while maintaining controlled flight.

Allowing for a ±10 degree deviation recognizes the need for slight adjustments due to various factors such as wind, pilot input, and inherent aircraft characteristics during the maneuver. This level of precision helps pilots focus on essential skills such as maintaining control, understanding the aircraft's performance, and recognizing any potential signs of an impending stall.

Exceeding a ±10 degree deviation may introduce unnecessary challenges for the student pilot, making it difficult to effectively manage the aircraft at low airspeeds. It could also distract from the primary learning objectives associated with slow flight, such as coordination and overall situational awareness. Thus, the regulation of ten degrees strikes a balance between ensuring effective learning and the safety of the flight.
