Each degree on the scale of the sextant is equivalent to two degrees of angular distance between the objects (sun & horizon) actually observed.RADIO NAVIGATION: RADIO NAVIGATION involves the use of electromagnetic waves to find the position of the craft ADF VOR ILS RMI MLSAutomatic Direction Finding (ADF): Automatic Direction Finding (ADF) It is a navigational aid that is used for automatic determination of relative bearing to a transmitting radio station or non-directional beacon (NDB). 190 kHz – 1860 kHz Used in 1935ADF Operation: ADF Operation NDB at ground transmits AM signal in omni-directional pattern The receiver on the aircraft receives the signal in a combined loop and sense antenna to give the relative bearing The ADF receiver swings a pointer on the instrument panelPowerPoint Presentation: ADF DialRadio Magnetic Indicator (RMI): Radio Magnetic Indicator (RMI) Shows both the bearing indicator and the heading indicatorVERY-HIGH FREQUENCY NAVIGATION SYSTEM: VERY-HIGH FREQUENCY NAVIGATION SYSTEM The VHF navigation system gives lateral guidance in airway flights or lateral and vertical guidance in approach. In addition, it gives distance information to the runway at fixed points.Ground Stations: Ground Stations VOR -beacon for lateral guidance in airway flights. US Standard in 1946 ICAO Standard in 1949 ILS -beacons for lateral and vertical guidance during the approach. US Standard in 1942 ICAO Standard in 1947 Marker Beacon- for distance information to the runway.VOR Purpose: VOR Purpose To provide the crew with relative bearing of the station & course deviation.VOR: VORVOR Station: VOR Station 25 to 200 W 108 to 117.95 MHz 50kHz/ch 200 chVOR Operation: VOR Operation VOR beacon (ground) transmits signals (radials) in all directions VOR beacon transmits two modulating signals – a 30 Hz reference signal and a 30 Hz variable signal At VOR receiver, radial is measured from the diff. in phase between the two transmitted signals Navigation indicator You do not have the permission to view this presentation.
