For example, if the magnetic heading of a runway is 233°, it is designated Runway 23. If the magnetic heading changes downwards by 5 degrees to 228°, the runway remains Runway 23. If on the other hand the original magnetic heading was 226° (Runway 23), and the heading decreased by only 2 degrees to 224°, the runway becomes Runway 22.
9, 10 - Effects of crosswind and tidal current, causing the vessel's track to differ from its heading. A, B - Vessel's track. TVMDC,AW is a mnemonic for converting from true heading, to magnetic and compass headings. TVMDC is a mnemonic initialism for true heading, variation, magnetic heading, deviation, compass heading, add westerly. The most ...
The CDI was designed to interpret a signal from a VOR, LDA, or ILS receiver. These receivers output a signal composed of two AC voltages. When used with a VOR, a converter decodes this signal, and, by determining the desired heading or radial from a resolver connected to the OBS knob, provides a 150mV control signal to drive the CDI needle left or right.
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed.
Runways are designated by a number between 01 and 36, which is generally one tenth of the magnetic azimuth of the runway's heading: a runway numbered 09 points east (90°), runway 18 is south (180°), runway 27 points west (270°) and runway 36 points to the north (360° rather than 0°). [11]
Each indicated airport has an airport data block associated with it. The block may contain just the name, altitude and runway length, or any of the following additional information, among others. Part-time tower operation (a star symbol). FSS, ATIS/AWOS, CTAF indicators; Control tower, ATIS, UNICOM frequencies, as available; Right traffic ...
For example, if the wind is at 09015 that means the wind is currently from heading 090 degrees with a speed of 15 knots and the aircraft is taking-off from runway 24; having heading of 240. The pilot prefers the runway side with less than 90 difference from wind direction, in this case Runway 06; heading 060.
Flying a vector SID may require first flying an obstacle departure procedure (ODP). This is usually annotated in the ODP section stating, "Fly runway heading to (xxx altitude) prior to making any turns." This ensures the aircraft is clear of any obstacles.
