A knot is a unit of speed used in aviation and maritime navigation. It is equivalent to one nautical mile per hour (1 nm/h), and it is used to express the speed of an aircraft or a ship in a way that is consistent with the way distances are expressed in nautical miles.

The knot is a standard unit of speed that is widely used in aviation and maritime navigation, and it is the standard unit of speed used by pilots, air traffic controllers, and marine navigators. In aviation, knots are used to express the speed of an aircraft relative to the ground, as well as the speed of wind and currents.

One knot is equal to 1.150779 miles per hour, or 1.852 kilometers per hour. To convert knots to miles per hour or kilometers per hour, simply multiply the number of knots by the appropriate conversion factor.

In aviation, knots are an important unit of measurement for air traffic control, flight planning, and aircraft performance. By using a standardized unit of speed, aviation professionals are able to easily and accurately communicate information about flight speed, wind speed, and other factors that affect flight operations.

Overall, the knot is an essential unit of speed in aviation and maritime navigation, providing a standard and consistent way to express speed and to facilitate communication and coordination among aviation professionals and other stakeholders.
A kneeboard is a small clipboard or writing tablet that is worn on the thigh of a pilot during flight. It is used to hold and organize important flight information and documents, such as navigation charts, flight plans, checklists, and performance calculations. The kneeboard provides quick and easy access to this information, allowing the pilot to focus on flying the aircraft.

Kneeboards come in a variety of sizes and styles, and some models are specifically designed for use in different types of aircraft. Some kneeboards have pockets or straps to hold pens, flashlights, or other small items, while others have built-in compasses, timers, or other aviation tools.

The use of a kneeboard is a common practice among pilots, as it provides a convenient and organized way to manage flight information. It is particularly useful for single-pilot operations, as it enables the pilot to manage information and complete tasks without having to reach for items that are stored elsewhere in the aircraft.

In addition to its practical benefits, the kneeboard is also an important safety item. By keeping critical flight information within reach and easily accessible, the kneeboard helps to reduce distractions and minimize the risk of errors during flight.
True Airspeed (TAS) is the actual speed of an aircraft relative to the airmass through which it is flying. Knots True Airspeed (KTAS) is a unit of measurement for TAS, expressed in nautical miles per hour (knots). TAS takes into account factors such as air temperature and pressure, and is therefore a more accurate representation of an aircraft's speed than indicated airspeed (IAS), which does not account for these factors. KTAS is used in navigation, flight planning, and performance calculations.
