Twenty-one knowledge elements, thirteen skills — and they are about different things

Elements The ACS asks for Where in FAA-H-8083-31B Read it for
K1, K2, K4, K5 Radio principles and components; interphone; VHF, HF, SATCOM Ch. 11 — Radio Communication; Radio Transmitters & Receivers; Radio Waves; Types of Radio Waves What the box does, enough to install and isolate it
K6–K21 ACARS; ELT; ADF; VOR; DME; ILS; GPS; TCAS; weather radar; GPWS; autopilot; auto-throttle; SAS; radio altimeter; ADS-B; transponder Ch. 11 — Radio Navigation; VOR Navigation System; Area Navigation (RNAV); Radar Beacon Transponder; Radio Altimeter; Radio Magnetic Indicator (RMI) The same — function, not repair
K3 Antennas, static discharge wicks and avionics identification and inspection Ch. 11 — Antennas; Installation of Aircraft Antenna Systems; Static Discharge Wicks The actual subject of the skills. AF-I Concepts §1
R1 ELT testing procedures — AF-I Concepts §4 — there are rules and they catch people
R2–R6 High power and high frequency systems; harness routing; antenna mounting; electrostatic discharge; live systems Ch. 11 — Reducing Radio Interference; Installation of Aircraft Antenna Systems AF-I Concepts §3
