Airspace & Requirements  AGL – Above Ground Level – describes the literal height above the ground over which you are flying. MSL – Mean Sea Level – is your true altitude or elevation. A plane that flies at 10,000 feet MSL and stays levels registers as flying at 10,000 feet MSL, no matter the terrain changes below the pilot. Pilots use altimeters, which measure the AGL, when the aircraft is flying at relatively low heights landing at an airport. As the plane increases in altitude, the altimeter reading becomes less accurate. Once the plane reaches transition altitude, the aircraft uses the MSL.  Statute Mile vs Nautical Mile Statute Mile – (Land mile) What we know as a mile. 5,280 feet or 1,760 yards. Nautical Mile – is the length of one arc minute measured along any meridian. It is equal to the length of one arc minute along the equator. = 1.15 miles or 6,076.12 feet  Class Bravo – Lateral Limits: The outer limits of the airspace will not exceed a 30 NM radius from the primary airport. This 30 NM radius will generally be divided into 3 concentric circles An inner 10 NM radius – May be subdivided based on operational needs, runway alignment, adjacent regulatory airspace, or adjacent airports – Areas between 10 – 20 NM and 20-30 NM may be vertically subdivided because of terrain or other regulatory airspace. A middle 20 NM radius An outer 30 NM radius Temporary Flight Restrictions (TFR) – A short term airspace restriction in a specific area. A notice to Airmen (NOTAM) is published by the FAA to announce the flight restriction. TFRs are imposed to: Protect persons and property in the air on the surface from an existing or imminent flight associate hazards Provide a safe environment for the operation of disaster relief aircraft Prevent an unsafe congestion of sightseeing aircraft above an incident Protect the President, Vice President, or other public figures Provide a safe environment for space agency operations Flight in TFRs are Prohibited Without Authorization
