constant. The angle of bank will depend upon the size of the arc, wind, and true
airspeed (TAS). This technique is more suitable when flying a relatively small arc at
a high airspeed.
7.9.3.2. Short Legs. Fly a series of short, straight legs to maintain the arc. To fly an
arc in this manner, adjust the aircraft heading to place the bearing pointer 5° to 10°
above the selected reference point. Maintain heading until the bearing pointer moves
5° to 10° below the reference point. The range should decrease slightly while the
bearing pointer is above the reference point, and increase slightly when below the
reference point. The arc is more closely maintained by flying shorter legs, controlling
the heading to keep the bearing pointer nearer to the reference point. Adjust heading
and reference point as necessary.
