  2. Intersection (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Intersection_(aeronautics)

    Terminal Procedure with Approach Intersections. In aviation, an intersection is a virtual navigational fix that helps aircraft maintain their flight plan.It is usually defined as the intersection (in the geometrical sense) of two VOR (VHF Omnidirectional Range) radials.

  3. Flight plan - Wikipedia

    en.wikipedia.org/wiki/Flight_plan

    Flight plans are highly recommended, especially when flying over inhospitable areas such as water, as they provide a way of alerting rescuers if the flight is overdue. In the United States and Canada, when an aircraft is crossing the Air Defense Identification Zone (ADIZ), either an IFR or a special type of VFR flight plan called a DVFR ...

  4. Aeronautical chart - Wikipedia

    en.wikipedia.org/wiki/Aeronautical_chart

    An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...

  5. Initial approach fix - Wikipedia

    en.wikipedia.org/wiki/Initial_approach_fix

    The initial approach fix is usually a designated intersection, VHF omnidirectional range (VOR), non-directional beacon (NDB), or distance measuring equipment (DME) fix. The initial approach fix may be collocated with the intermediate fix (IF) of the instrument approach and in such case they designate the beginning of the intermediate segment of ...

  6. Heathrow arrival stacks - Wikipedia

    en.wikipedia.org/wiki/Heathrow_arrival_stacks

    Inbound aircraft to London Heathrow Airport typically follow one of a number of Standard Terminal Arrival Routes (STARs The STARs each terminate at one of four different RNAV waypoints (co-located with VOR navigational aids), and these also define four "stacks" [1] where aircraft can be held, if necessary, until they are cleared to begin their approach to land.

  7. Localizer performance with vertical guidance - Wikipedia

    en.wikipedia.org/wiki/Localizer_Performance_with...

    Landing minima are usually similar to those of a Cat I instrument landing system (ILS), that is, a decision height of 200 feet (61 m) and visibility of 800 m. [1] Lateral guidance is equivalent to a localizer, and uses a ground-independent electronic glide path. Thus, the decision altitude, DA, can be as low as 200 feet. An LPV approach is an ...

  8. Approach plate - Wikipedia

    en.wikipedia.org/wiki/Approach_plate

    An approach plate for the ILS or LOC approach to runway 14L at Cologne Bonn Airport, Germany. Approach plates (or, more formally, instrument approach procedure charts) are the printed or digital charts of instrument approach procedures that pilots use to fly instrument approaches during instrument flight rules (IFR) operations.
