    • Correction Phrase - "CORRECTION" is used to correct a previous message.
    • Stuck Microphone Button - A microphone button stuck on transmit will block the frequency for others.
    • ATC Clearance Readback Termination - Terminate the readback of an ATC clearance with the word "WILCO."
    • Heavy Wake Turbulence Aircraft Call Sign - Heavy wake turbulence aircraft should include "HEAVY" after their call sign on initial calls to the tower and approach control.
    • Message Priority - "REQUEST QDM" (request magnetic bearing) has higher priority than instructions like "TURN LEFT HEADING."
    • "TRANSMITTING BLIND DUE RECEIVER FAILURE" Message - This message is transmitted on the same frequency currently in use by the aircraft.
    • QNH - QNH is the pressure at the aerodrome reduced to sea level.
    • QDR vs. QTE - QDR is magnetic bearing from the station, while QTE is true bearing from the station.
    • VHF Communication Range - Extended ranges in VHF communications can occur through super refraction.
    • PAN Message - A PAN (Pan-Pan) message indicates a situation that poses a serious or imminent danger but does not require immediate assistance.
    • "TAKE OFF" Phrase - Only use "TAKE OFF" when an aircraft is cleared for takeoff or when cancelling a takeoff clearance.
