Radio Wavelength
Wavelength of a radio signal is the speed of light divided by its frequency; it sets antenna length and dish sizing.

Example
A 113 MHz VOR signal: λ = 3×10⁸ ÷ 113×10⁶ ≈ 2.65 m
Did You Know?
A quarter-wave VHF comms antenna at 120 MHz is only ~62 cm long — short enough to sit as a small blade on the fuselage.

DME Slant Range Correction
BasicDME measures the direct (slant) distance to the beacon; the true ground distance is found by removing the height component.

One-in-Sixty Rule

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.
