    If elevation is required, then ERROR_ELEVATION_REQUIRED will be returned. [23] If elevation is not required, a success return code will be returned at which point one can use TerminateProcess() on the newly created, suspended process. This will not allow one to detect that an executable requires elevation if one is already executing in an ...

    The arrow represents a rootkit gaining access to the kernel, and the little gate represents normal privilege elevation, where the user has to enter an Administrator username and password. Privilege escalation is the act of exploiting a bug , a design flaw , or a configuration oversight in an operating system or software application to gain ...

  4. Elevation - Wikipedia

    en.wikipedia.org/wiki/Elevation

    In aviation, the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is not to be confused with terms such as the altitude or height.

    The datum surface may be real or imaginary location with a nominated elevation of zero. The commonly used datum is mean sea level. [3] Dumpy level – optical instrument used to establish or check points in the same horizontal plane. It is used in surveying and building with a vertical staff to measure height differences and to transfer ...

  7. Height above mean sea level - Wikipedia

    en.wikipedia.org/wiki/Height_above_mean_sea_level

    Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods.

  8. Hot and high - Wikipedia

    en.wikipedia.org/wiki/Hot_and_high

    In aviation, hot and high is a condition of low air density due to high ambient temperature and high airport elevation. Air density decreases with increasing temperature and altitude. The lower air density reduces the power output from an aircraft's engine and also requires a higher true airspeed before the aircraft

    This requires the use of special coatings to protect objects and equipment in this orbit. In VLEO orbit, estimates are that up to 96% of the atmosphere is AO. [ 21 ] At VLEO altitudes, the total amount of O atoms rises exponentially the lower the altitude, and is orders of magnitude greater than that encountered by the ISS at 400 km altitude.
