NIFE Air Nav All ELOs Latest Update Already Passed Describe the types of air nav, dead reckoning, visual nav and electronic nav Three Types: Dead Reckoning: Directing an aircraft and determining its position by the application of direction and speed data from a previous position. Use Position, direction, time and speed. Primary method of Navigation Visual Navigation: Requires maintaining direct visual contact with earths surface. can be used in conjunction with dead reckoning to determine position from ground identifiers. Electronic navigation: Use of electronic devices to determine position. Received from ground stations, self transmitting signal navigation and inertial navigation requiring the starting point. Describe the four basic elements of dead reckoning navigation The four basic elements of dead reckoning are Position: described by coordinates Direction: angular distance from a reference. 001-360 degrees. Time speed: distance measured with respect to time Describe the flight instruments used in dead reckoning BDHI/Remote Gyro vertical compass card: direction and position Clock: Time Airspeed indicator: speed secondary: OAT and altimeter provide air density effects to get a more accurate reading. Describe a TANCAN Ground based system that provides aviator with precise position information. provides distance in NM away and gives magnetic bearing to the station. Describe a great circle route A Great circle is a circle formed by continuing the arc inscribed by connecting the shortest distance between two points on a sphere. Only one parallel, the equator forms a great circle, all meridians are great circles since they vertically bisect the earth. Describe a lambert conformal chart Developed by placing a secant cone over the earth, bisecting at two lines on longitude called standard parallels. Parallels: equally spaced concentric circles meridians: straight lines converging at the poles scale: constant distance scale great circle: plot as straight lines. ONC:1:1000000 for long range nav TPC:1:500000 most common. Course Vs heading Vs Track Course: aircrafts intended flight path Heading: Direction the nose of the aircraft is pointed Differs from course to compensate for crosswind Track: aircrafts actual flight path over the ground. Explain magnetic variation Variation is the angular difference from true north and magnetic north from any given position on the earths surface. Expressed in degrees east or west. Compute magnetic directions using magnetic variation, whats the phrase East is least (- east, add west) MC=TC-east MC=TC+west Describe and solve global timekeeping problems Local mean time Vs zulu time
