Radar Range Resolution
Smallest separation at which two targets appear as distinct echoes, set by the transmitted pulse width.
Formula
Variables
Example
1 µs pulse: ΔR = 3×10⁸×10⁻⁶ ÷ 2 = 150 m
Did You Know?
To resolve closely spaced targets radars use very short pulses — or pulse-compression chirps — so a long-range radar can still separate objects only metres apart.

BasicMaximum line-of-sight range to the radio horizon for a VHF antenna, driven by antenna height and the curvature of the Earth.
Radio Wavelength
BasicWavelength of a radio signal is the speed of light divided by its frequency; it sets antenna length and dish sizing.
DME Slant Range Correction
BasicDME measures the direct (slant) distance to the beacon; the true ground distance is found by removing the height component.
ILS Glideslope Height
BasicHeight an aircraft should be above the runway threshold when established on the ILS glideslope at a given distance.
One-in-Sixty Rule
BasicRule-of-thumb linking a lateral track error to an angular deviation: 1 nm off after 60 nm is about 1° of error.
Mode C Altitude Reporting
BasicA Mode C/S transponder reports pressure altitude referenced to 1013.25 hPa; dividing by 100 gives the flight level, independent of the local altimeter setting.
