Chapter lessons
1Radio Waves and PropagationRelate frequency, wavelength, propagation and line-of-sight range without reversing the common day, night and attenuation traps.2NDB and ADFExplain how an NDB and ADF provide relative bearing and identify the main ADF error families.3VORExplain phase comparison, radials, coverage and the main VOR limitations.4ILSDistinguish localizer and glide-path guidance, frequency pairing, coverage and false indications.5DME and RadarDistinguish DME slant range from ground range and compare primary and secondary radar principles.6GPS and GNSSExplain satellite ranging, the minimum satellite counts and the principal GNSS error and integrity concepts.7Airborne Weather RadarInterpret precipitation returns, tilt, attenuation and the hazards that airborne weather radar cannot show.
