NIFE Nav Exam Questions and Answers With Verified Solutions 2025
Describe the basic concepts, principles, and terminology used in air navigation - ✔✔Air navigation is the
process of determining the geographic position and maintaining the desired direction of an aircraft
relative to the surface of the earth
Describe types of air navigation - ✔✔Dead reckoning - directing an aircraft and determining its position
by the application of direction and speed (time/speed/distance).
Visual Navigation - Requires maintaining direct visual contact with the ground. Use ground references to
determine current position.
Electronic Navigation - Uses electronic devices to send and receive signals to determine position.
Describe the four basic elements of dead reckoning navigation - ✔✔Position is a geographic point
determined by coordinates (latitude/longitude)
Direction is an angular distance from a reference
Time can be elapsed time or time of day (must be written in zulu time)
Speed is the magnitude of the velocity of an aircraft (speed = distance/time)
Describe the flight instruments used in dead reckoning navigation - ✔✔The Bearing Distance Heading
Indicator (BDHI)/remote gyro vertical compass card, the clock, and the airspeed indicator are the
primary instruments.
Altimeter and outside air temperature (OAT) gauge also help calculate the effects of air density
Describe a great circle route - ✔✔A great circle passes through the earths center dividing the earth into
2 equal halves. The only parallel that is a great circle is the equator, but every meridian is a great circle.
Describe Lambert Conformal charts - ✔✔The most common projection.
Parallels are equally spaced concentric circles.
Meridians are straight lines converging at the poles.
Scale is a constant distance scale.
Great circles are plot as straight lines.
Can be operational navigation chart (ONC, 1:1,000,000) or tactical pilotage chart (1:500,000).
