  2. Maximum elevation figure - Wikipedia

    en.wikipedia.org/wiki/Maximum_Elevation_Figure

    The MEF on Canadian VFR navigation charts is calculated by taking the higher value of: the top elevation of the highest obstacle plus the vertical accuracy (a variable number of feet) of the terrain source data; or; the elevation of the highest terrain plus 328 feet plus the vertical accuracy variable of the terrain source data. [1]

  3. DTED - Wikipedia

    en.wikipedia.org/wiki/DTED

    The DTED format for level 0, 1 and 2 is described in U.S. Military Specification Digital Terrain Elevation Data (DTED) MIL-PRF-89020B, and amongst other parameters describes the resolution for each level: Level 0 has a post spacing of approximately 900 meters. Level 1 has a post spacing of approximately 90 meters.

  4. Density altitude - Wikipedia

    en.wikipedia.org/wiki/Density_altitude

    Density Altitude Computation Chart [1] The density altitude is the altitude relative to standard atmospheric conditions at which the air density would be equal to the indicated air density at the place of observation. In other words, the density altitude is the air density given as a height above mean sea level.

  5. Formation skydiving - Wikipedia

    en.wikipedia.org/wiki/Formation_skydiving

    4-way FS (Formation Skydiving) Breaking off from a formation before parachute deployment. DC-3 loading; plus 'dirt diving'; 1977. Formation skydiving is a skydiving event where multiple skydivers attach themselves to one another by grabbing each other's limbs or by the use of "grippers" on their jumpsuit while free falling through the sky.

  6. Speed skydiving - Wikipedia

    en.wikipedia.org/wiki/Speed_skydiving

    The first speed skydiving competition in Europe [2] was organized in September 1999 at the drop zone Gap-Tallard (France) and was won by Mike Brooke. [3] [4] [5] The first international world cup was organized in 2000 [6] [7] by the ISST (International Speed Skydiving Tribe) led by Mike Brooke who pushed the sport forwards with use of two ...

  7. 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 ...

  8. Tracking (skydiving) - Wikipedia

    en.wikipedia.org/wiki/Tracking_(skydiving)

    Good trackers can cover nearly as much ground as the distance they fall, approaching a glide ratio of 1:1. The fall rate of a skydiver in an efficient track is significantly lower than that of one falling in a traditional face-to-earth position; the former reaching speeds as low as 40 metres per second (90 mph), the latter averaging around the 54 m/s (120 mph) mark.

  9. Reference datum height - Wikipedia

    en.wikipedia.org/wiki/Reference_datum_height

    In aviation, reference datum height (RDH) is the height of a point, located above the intersection of the runway centre line and the threshold, through which the downward extended straight portion of the glide path passes. [1] It is usually found on the aerodrome instrument approach charts.
