Vref speed is the reference speed for approach, which is the speed at which the aircraft is flown during the approach to landing. It is one of the V-speeds, which are standard terms used to define airspeeds important or useful to the operation of all aircraft. Learn more about the V-speeds, their definitions, and their applications in aviation.
Learn how to measure and convert the heading of a vessel or aircraft, the compass direction in which the craft's bow or nose is pointed. Find out the factors that affect the heading, such as magnetic variation, deviation, and drift.
A knot is a unit of speed equal to one nautical mile per hour, which is approximately 1.852 km/h or 1.151 mph. Learn about the history, definitions, conversions and usage of the knot in meteorology, maritime and aviation.
Learn how different frames and conventions use the Z axis to describe the orientation and motion of vehicles and objects in various domains. Compare the Z axis meanings in earth-bound, space, and aircraft axes systems with diagrams and explanations.
Learn about the science of air vehicle orientation and control in three dimensions, including pitch, roll and yaw angles. Find out how flight path angle is defined and related to other parameters such as heading angle and bank angle.
Hull speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. Learn how to calculate hull speed, its implications for wave-making resistance and hull design, and its relation to ship drag and Froude number.
Learn about the definition, calculation and use of indicated airspeed (IAS), the airspeed of an aircraft as measured by its pitot-static system and displayed by the airspeed indicator. Find out how IAS differs from true airspeed (TAS), calibrated airspeed (CAS) and equivalent airspeed (EAS) and why it is important for pilots.
Course over ground is the path that a vessel follows over the ground, not the direction it is pointed. Learn how to distinguish course, heading, track and route in navigation, and how to compensate for drift and magnetic variation.
