In private aviation, airspeed refers to the speed of a jet charter relative to its surrounding air mass. Within this definition, there are four common ways of measuring airspeed:
Indicated airspeed: the speed of a charter plane as shown on the aircraft’s airspeed indicator. It is uncorrected for instrument, position and other errors.
Calibrated airspeed: the speed of a charter plane that has been corrected for instrument and position errors.
Equivalent airspeed: the speed at sea level that would produce the same incompressible dynamic pressure as the true airspeed of a jet charter flying at a given altitude.
True airspeed: the speed of a jet charter relative to the atmosphere.
Travelling at the Speed of Business
Along with range, the airspeed (or, more appropriately, cruising speed) of a jet charter is an important consideration when choosing the right aircraft for a given charter flight. For busy corporate executives who need to keep tight schedules, having a charter plane with the speed to get them to their appointments is critical.
Additionally, the speed of a jet charter becomes more pronounced the further it travels. For instance, a Gulfstream G650 charter can complete transoceanic missions much faster than many of its class competitors. This can amount to hours in time savings for ultra-long range business trips.
