Chapter 16: Navigation Flashcards
What are the three methods of navigation described in Chapter 16?
- Pilotage
- Dead reckoning
- Radio navigation
What is pilotage?
Navigating by reference to visible landmarks.
What is dead reckoning?
Navigation based on computations of time, airspeed, distance, and direction.
What is radio navigation?
Navigation using radio aids such as VOR, NDB, and GPS.
What are the three types of aeronautical charts for VFR pilots?
- Sectional charts
- VFR terminal area charts
- World aeronautical charts
What is the scale of a sectional chart?
1:500,000 (1 inch = 6.86 NM or approximately 8 SM).
What is a VFR terminal area chart used for?
Provides detailed topographical information for Class B airspace.
What is the primary purpose of the equator in navigation?
To measure degrees of latitude north or south.
What are meridians of longitude?
Imaginary lines running from the North Pole to the South Pole, used to measure degrees east or west of the Prime Meridian.
How is Universal Coordinated Time (UTC) calculated?
Convert local time to UTC by adding:
Eastern Time: +5 hours
Central Time: +6 hours
Mountain Time: +7 hours
Pacific Time: +8 hours.
What is magnetic variation?
The angle between true north (TN) and magnetic north (MN).
What is the agonic line?
A line where magnetic variation is zero.
What is the difference between true course (TC) and true heading (TH)?
TC: Direction of intended flight over the ground.
TH: Direction the aircraft points during flight.
What is wind correction angle (WCA)?
The correction applied to account for wind drift, expressed in degrees right or left of the true course.
What is the formula for calculating compass heading (CH)?
CH = TC ± WCA ± Variation ± Deviation.
