NIFE Nav Questions with Answers (100%
Correct Answers)
What are the 3 types of air navigation? Answer: 1. Dead reckoning
2. Visual navigation
3. Electronic navigation
Define air navigation Answer: The process of determining the geographic
position and maintaining the desired direction of an aircraft relative to the
surface of the earth
Define dead reckoning Answer: Directing an aircraft and determining its
position by the application of direction and speed data from a previous position
What are the 4 components of dead reckoning? Answer: PTSD
Position
Time
Speed
Direction
Define position Answer: a geographic point defined by coordinates
What is the angular distance north or south of the equator? Answer: latitude
What is the angular distance east or west of the prime meridian? Answer:
longitude
Lines of latitude are also called? Answer: parallels
Lines of longitude are also called? Answer: meridians
, 2
Lat/long are measured in? Answer: degrees and minutes; 60 minutes in each
degree
Longitude starts at __ degrees at ________ and ends at ___ degrees at
________. Answer: 0, prime meridian, 180, international date line
Define direction Answer: angular distance from a reference; measured from
001 degrees to 360 degrees
What is the primary instrument for measuring direction? Answer: Remote
Gyro Vertical Compass Card / BDHI / EHSI; use gyros!
What is the backup / secondary instrument for measuring direction? Answer:
Standy-by / "wet" compass that gives direct compass readings, filled with fluid
to dampen needle movement
What are the 2 ways time can be expressed? Answer: time of day, elapsed time
Define speed Answer: the magnitude of the velocity of an aircraft; speed =
distance / time
What are the 3 primary instruments for dead reckoning? What are they used
for? Answer: 1. BDHI - position and direction
2. clock - time
3. airspeed indicator - speed
What are the 2 secondary instruments for dead reckoning? What are they used
for? Answer: 1. outside air temp gauge (OAT)
2. altimeter (altitude)
used for figuring out density so we can get TAS
What is a TACAN? Answer: Tactical air navigation system: ground-based
system that provides the aviator with precise position information by providing
