  2. Lowest safe altitude - Wikipedia

    en.wikipedia.org/wiki/Lowest_safe_altitude

    In aviation (particularly in air navigation), lowest safe altitude (LSALT) is an altitude that is at least 500 feet above any obstacle or terrain within a defined safety buffer region around a particular route that a pilot might fly. The safety buffer allows for errors in the air by including an additional area that a pilot might stray into by ...

  3. Minimum safe altitude warning - Wikipedia

    en.wikipedia.org/wiki/Minimum_Safe_Altitude_Warning

    ICAO Doc 4444 requires that radar systems should provide for the display of safety-related alerts including the presentation of minimum safe altitude warning. [2] The radar equipment predicts an aircraft’s position in 2 minutes based on present path of flight, and the controller issues a safety alert if the projected path encounters terrain or an obstruction.

    ATC will assign altitudes in its initial clearance or amendments thereto, and navigational charts indicate minimum safe altitudes for airways. [ citation needed ] The approach portion of an IFR flight may begin with a standard terminal arrival route (STAR), describing common routes to fly to arrive at an initial approach fix (IAF) from which an ...

    Though specific altitudes are called as noted below - there is an overreaching general requirement to maintain sufficient altitude that if a power unit fails, an emergency landing without undue hazard to persons or property on the surface can be made. This may be significantly higher than 500 feet or 1,000 feet. 500 ft rule

  9. Minimum en route altitude - Wikipedia

    en.wikipedia.org/wiki/Minimum_en_route_altitude

    Minimum en route altitude (MEA), [1] alternately spelled as Minimum enroute altitude, [2] is the lowest published altitude between radio navigation fixes that assures acceptable navigational signal coverage (see MRA) and meets obstacle clearance requirements (see MOCA) between those fixes.
