When beginning a rectangular course, what factor is crucial in deciding how far from the field boundary the aircraft should be flown?

When beginning a rectangular course, the steepness of the bank desired in the turns is crucial for determining how far from the field boundary the aircraft should be flown. This is because the radius of the turn is directly influenced by the bank angle; a steeper bank will result in a tighter turn, requiring the aircraft to be flown closer to the field boundary. Conversely, if a shallower bank is used, the turn will be wider, necessitating a greater distance from the boundary to ensure safe clearance.

Moreover, maintaining the appropriate distance from the boundary while factoring in the desired bank angle helps pilots avoid potential obstacles and ensures a safe and controlled maneuver. The relationship between bank angle and turn radius is essential for maintaining the geometry of the rectangular flight path, allowing the pilot to accurately navigate the course while managing the aircraft's performance characteristics effectively.
