General Airspeed Terminology and Symbols

Knots calibrated airspeed

Indicated airspeed corrected for for position and instrument erros.

Knots indicated airspeed

The airspeed shown on the airspeed indicator expressed in knots

The maximum speed at which you may use abrupt changes = 90

is hte highest speed allowed to extend wing flaps = 85-87

Maximum crusing speed through rough air 108

Stalling speed or mimimum steady flight speed in the landing configuration = 35 knots

Stalling speed or minimum steady flight speed without flaps or landing gear present = 40 knots

Rotation speed = 50

Best angle of climb = 55

Most altitude gained over a horizontal distance

Best rate of climb = 67

Most altitude gained over a given amount of time

speed of 70 to 80

Never exceed speed 145

Imaginary vertical plane from which all horizontal distances are measured for balance purposes

product of weight multiplied by arm
