Principles of Navigation Quiz Flashcards
Define Pilotage.
Pilotage is navigation by reference o landmarks or checkpoints. Pilotage is determined by having
an overall heading, overall time, and overall fuel burn
Define Dead Reckoning
Dead reckoning is a method of navigation relying on estimating your current track, groundspeed, and position based on earlier known positions. Dead reckoning is determined by using the heading, groundspeed, leg time, and fuel burn between each leg.
How does one determine true course?
To determine true course, the best way is to use a plotter on a VFR sectional. In order to use the plotter, a line must be drawn on the map that the protractor part of the plotter can be used against.
What is magnetic variation?
Magnetic variation is the angular difference between True North and Magnetic North.
Are winds aloft measured in true or magnetic?
True
How does one determine magnetic course?
Magnetic course = True Course + Magnetic Variation + Course Deviation
How does one determine wind correction angle?
The E6B is the easiest way to determine a wind correction angle. It will ask for the wind direction, wind speed, and the true heading.
What is calibrated air speed and how is it determined?
Calibrated airspeed (CAS) is the indicated airspeed of an aircraft corrected for position and instrument error. It is determined via the POH.
What is true air speed and how is it determined?
True airspeed (TAS) is the speed of an aircraft relative to undisturbed air. It can be determined via the POH.
How does one determine ground speed while in flight?
Groundspeed can be determined by calculating the time between known points compared to the known distance between those points.
Describe acceleration and deceleration error of the magnetic compass.
Acceleration/deceleration error of the magnetic compass is the tendency of the compass to swing a little North (accelerating) or South (decelerating) while on a heading of East or West
Describe magnetic dip error
The Earth’s magnetic field runs parallel to its surface only at the Magnetic Equator, which is the point halfway between the Magnetic North and South Poles. As you move away from the Magnetic Equator towards the magnetic poles, the angle created by the vertical pull of the Earth’s magnetic field in relation to the Earth’s surface increases gradually. This angle is known as the dip angle. The dip angle increases in a downward direction as you move towards the Magnetic North Pole and increases in an upward direction as you move towards the Magnetic South Pole.
What is an isogonic line?
An isogonic line is a line drawn across aeronautical charts connecting points that have the same magnetic variation
What is a agonic line?
An agonic line is an isogonic line that has no magnetic variation
