The correct answer is B. Converting from true course to magnetic heading is a two-step process. The pilot would first subtract left or add right wind correction angle, then subtract easterly or add westerly variation. (Pilot’s Handbook of Aeronautical Knowledge, Chapter 15)
The pilot would first subtract left or add right wind correction angle, then subtract easterly or add westerly variation. ( Pilot’s Handbook of Aeronautical Knowledge, Chapter 15) 2. The correct answer is C. At low speeds, very little excess load can be imposed on the wing of an airplane before it will stall.
If a true heading of 135° results in a ground track of 130° and a true airspeed of 135 knots results in a groundspeed of 140 knots, the wind would be from 246° and 13 knots. When converting from true course to magnetic heading, a pilot should...
Magnetic heading is the direction the aircraft is pointing, given by reference to a magnetic compass. The magnetic compass will always be aligned with the north magnetic pole. It is important to note that it is notthe same as the geographicNorth pole!
MC = 212° TC + 7°W variation = 219°. 4. Wind magnetic = 090° + 7°W variation = 097°. 5. Mark up 16 knots with 097° under true index.
To convert from the chart's true course to a magnetic course, pilots must add or subtract the variation. Whether they add or subtract depends on whether the pilot is in an area of westerly or easterly variation. Slides 10-13: A pilot flying in the western half of the United States is in an area of easterly variation.

The "heading" refers to the direction an aircraft is pointing. For a Magnetic Heading, this is in relation to Magnetic North. For a True Heading, this is in relation to True North. True North is directly over the earth's axis.
True Course: The aircraft's course over the ground relative to true north. True course is measured with a navigation plotter and a sectional map. True Heading: True course corrected for wind.
Determination of True Bearing From Magnetic Bearing RulesIf Declination is East. True Bearing(T.B) = [Magnetic Bearing(M.B) + Declination]If Declination is West. True Bearing = [Magnetic Bearing – Declination]
The difference is the 8° angle from True North to Magnetic North plus the 0° 23' angle from True North to Grid North. Thus to convert from a magnetic bearing to a Grid North reference you would subtract 8° 23'. (I would likely round this to 8 1/2°or just 8°.)
The angular difference between true north and magnetic north is known as the declination and is marked in degrees on your map as shown in Figure 6.7.
The difference between true and magnetic north varies by location and over time. In most populated parts of the world, it currently ranges from 30 degrees west (south-eastern tip of Africa) to 26 degrees east (southern tip of New Zealand). However, most locations on Earth have a considerably smaller declination.
True north is a fixed point on the globe. Magnetic north is quite different. Magnetic north is the direction that a compass needle points to as it aligns with the Earth's magnetic field. What is interesting is that the magnetic North Pole shifts and changes over time in response to changes in the Earth's magnetic core.
Compass course: (cc or CTS) the course which is corrected for both variation and deviation. Magnetic course: (mc) the course which is only corrected for variation. cc + var + dev = tc: this equation shows the connection between the compass course, its errors and the true course.
Since the beginning of flight, pilots have been using the magnetic compass for navigation. It doesn't matter if you're flying a Piper Cub or a Boeing 747, you'll find a magnetic compass in the cockpits of almost any aircraft.
