    Recreational Pilot: an individual who may fly aircraft of up to 180 horsepower (130 kW) and 4 seats in the daytime for pleasure only; Private Pilot: an individual who may fly for pleasure or personal business, generally without accepting compensation; Commercial Pilot: an individual who may, with some restrictions, fly for compensation or hire

  4. Visual flight rules - Wikipedia

    en.wikipedia.org/wiki/Visual_flight_rules

    The pilot must be able to operate the aircraft with visual reference to the ground, and by visually avoiding obstructions and other aircraft. [ 1 ] If the weather is less than VMC, pilots are required to use instrument flight rules , and operation of the aircraft will be primarily through referencing the instruments rather than visual reference.

  5. Flight level - Wikipedia

    en.wikipedia.org/wiki/Flight_level

    Flight levels [3] are described by a number, which is the nominal altitude, or pressure altitude, in hundreds of feet, and a multiple of 500 ft.Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320".

  6. Height above ground level - Wikipedia

    en.wikipedia.org/wiki/Height_above_ground_level

    In aviation, atmospheric sciences and broadcasting, a height above ground level (AGL [1] or HAGL) is a height measured with respect to the underlying ground surface.This is as opposed to height above mean sea level (AMSL or HAMSL), height above ellipsoid (HAE, as reported by a GPS receiver), or height above average terrain (AAT or HAAT, in broadcast engineering).

    en.wikipedia.org/wiki/X-15_Flight_91

    X-15 Flight 91 was an August 22, 1963 American crewed sub-orbital spaceflight, and the second and final flight in the program to fly above the Kármán line, which was previously achieved during Flight 90 a month earlier by the same pilot, Joseph A. Walker. It was the highest flight of the X-15 program.

  8. Lowest safe altitude - Wikipedia

    en.wikipedia.org/wiki/Lowest_safe_altitude

    For example, if there is an obstacle at 200 feet above terrain of 2500 feet, LSALT is 2500 feet (terrain height) + 1360 feet (clearance height), for an LSALT of 3860 feet; if there is an obstacle at 450 feet above terrain of 3600 feet, LSALT is 4050 feet (obstacle height) + 1000 feet (clearance height), or an LSALT of 5050 feet.

  9. Perlan Project - Wikipedia

    en.wikipedia.org/wiki/Perlan_Project

    That same year Jim Payne, holder of numerous world soaring records, joined the project as chief pilot. A great deal of design work has been done by Greg Cole of Windward Performance to show that a sailplane for 90,000 feet is relatively straightforward, while 100,000 feet is possible, although more difficult and expensive.
