But pilots aren't required to read 7110.65, so we have a regulatory connection based on assumption--and room for confusion now that another option besides magnetic heading exists.
Fly magnetic heading (presuming you're equipped to do so).
The D100 hasaG meter, timers, a voltmeter and accepts inputs from optional AoA and
magnetic heading sensors.
The airplane had impacted high-standing trees at an elevation of about 8900 feet msl, on a measured
magnetic heading of 355 degrees.
This difference between the magnetic course and the magnetic heading is called the wind correction angle.
Instead, most pre-flight planning these days is conducted online, and well-refined algorithms compute the results of a wind triangle for us, providing projected groundspeed and magnetic heading to steer, all in a nice, concise flight log we can print at the FBO and carry with us to the airplane.
Following our conversation, he did change the definition to then direct the pilot to fly the actual
magnetic heading of the runway, as it stands today.--D.B.
The distribution of wreckage roughly followed a 160-degree
magnetic heading and was approximately 250 feet long.
Preliminary examination of the accident site revealed the helicopter collided with trees approximately 40 feet above ground level while on a
magnetic heading of approximately 020 degrees.
