Certified Flight Instructor (CFI) Practice Exam

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

1. 5 degrees

2. 10 degrees

3. 15 degrees

4. 20 degrees

The correct answer is: 10 degrees

In the context of slow flight, the maximum allowable heading deviation being 10 degrees reflects the principles of maintaining control and situational awareness during this critical phase of flight. Slow flight involves flying at airspeeds just above the stall speed, where the aircraft is more susceptible to aerodynamic changes and control sensitivity. Allowing for a heading deviation of up to 10 degrees provides a reasonable margin for the pilot to manage the aircraft while avoiding excessive deviation that could lead to loss of control. At slower speeds, any uncommanded flight path deviations can lead to significant altitude loss or potential stalling, particularly if the aircraft is not properly coordinated. Understanding this maximum deviation is crucial for effective teaching and ensures that students appreciate the importance of maintaining precise control and awareness in varying flight regimes, especially when the aircraft is operating close to its performance limits. Regulation of heading deviation enhances safety and establishes healthy flying habits that are integral to being a proficient flight instructor.
