The term , where is the speed, and is the fuel consumption rate, is called the specific range (= range per unit mass of fuel; S.I. units: m/kg). The specific range can now be determined as though the airplane is in quasi-steady-state flight.
The lowest NOE flying is by helicopters because they have lower speeds and more maneuverability than fixed-wing aircraft, particularly fast jets. Helicopters can fly at treetop levels or even below the height of surrounding trees where there are clear areas (such as in river gullies), [ 1 ] flying under wires (such as electricity cables) rather ...
The Bill Noe Flight School is the flight school at Marshall University, located at the West Virginia Yeager International Airport in Charleston, West Virginia. [1] The Bill Noe Flight School features a 12,000 sq ft. academic building, a hangar, and an aircraft parking apron.
Stall speed or minimum steady flight speed for which the aircraft is still controllable. [7] [8] [9] V S 0: Stall speed or minimum flight speed in landing configuration. [7] [8] [9] V S 1: Stall speed or minimum steady flight speed for which the aircraft is still controllable in a specific configuration. [7] [8] V S R: Reference stall speed. [7 ...
This is the speed at which drag is minimised. For jet aircraft, "long-range cruise" speed (LRC) is defined as the speed which gives 99% of the maximum range, for a given weight. This results in a 3–5% increase in speed. [8] It is also a more stable speed than maximum range speed, so gives less autothrottle movement. [9]
Flight plans mix metric and non-metric units of measurement. The particular units used may vary by aircraft, airline, and location across a flight. Since 1979, [4] the International Civil Aviation Organization (ICAO) has recommended a unification of units of measurement within aviation based on the International System of Units (SI). [5]

(In an artificial and extreme case with the aircraft flying exactly at the exhaust speed, one can easily imagine why the jet's net thrust should be near zero.) Moreover, since work is force (i.e., thrust) times distance, mechanical power is force times speed. Thus, although the nominal SFC is a useful measure of fuel efficiency, it should be ...
