A knot (kt or kts) is a unit of speed used in aviation and maritime navigation, equal to one nautical mile per hour. Knots are the standard unit for expressing aircraft airspeed and ground speed, because they are directly tied to Earth’s geometry and navigation charts.

Key characteristics:

  • Definition:
    1 knot = 1 nautical mile per hour ≈ 1.852 km/h1.1508 mph
  • Notation:
    • KT and KTS are used interchangeably
    • “250 kt” and “250 kts” mean the same thing
  • Why knots are used:
    Nautical miles are based on latitude and longitude (1 NM = 1 minute of latitude), making knots ideal for navigation, timing, and distance calculations.
  • Common aviation speeds expressed in knots:
  • Operational relevance:
    Takeoff speeds, landing speeds, climb limits, holding patterns, and approach procedures are all defined in knots.

Application in DCS World

DCS uses knots as the primary speed unit across almost all aircraft modules. Airspeed indicators, HUDs, MFDs, and mission briefings typically display speeds in knots.

Pilots will encounter knots when:

  • Flying approach speeds and landing references
  • Managing energy in air-to-air combat
  • Executing CAS attack profiles
  • Navigating using timing and distance calculations

DCS does not require manual conversion between knots and other units during normal gameplay, but understanding the relationship between knots, nautical miles, and time is essential for realistic navigation and flight planning.

Cadets should develop an intuitive sense of speed in knots, learning what values “feel right” for climb, cruise, combat maneuvering, and approach. This is a core aviation skill that translates directly from simulation to real-world procedures.
