- Readback requirement
- Pilot must repeat back clearances, runway assignments, altimeter settings, headings, altitudes, frequencies, transponder codes, and conditional clearances to ensure correct understanding.
- Line up and wait
- ATC instruction allowing aircraft to enter runway and position for takeoff but not to begin takeoff roll. Requires readback including runway number.
- Hold short instruction
- ATC instruction to stop before a runway or taxiway. Must be read back with call sign and runway designator. Do not cross without explicit clearance.
- Conditional clearance
- Clearance that depends on a preceding condition, e.g., 'After the departing Cessna, line up runway 27.' Pilot must read back condition and clearance.
- Position report format
- Call sign, position, time, altitude, next position and ETA, following point. Used for en route reporting and search and rescue.

- Automatic Terminal Information Service broadcast containing weather, runway in use, and other aerodrome information. Pilots include ATIS letter on initial contact.
- VFR flight plan
- Plan filed for VFR flight, activated with ATC or FIS before departure, and closed upon arrival. Provides search and rescue alerting service.
- Special VFR clearance
- Clearance allowing VFR flight in controlled airspace when weather is below VMC minima. Requires request and ATC approval.

- Continue under VFR, land at nearest suitable aerodrome, and report arrival to ATC by telephone. Squawk 7600 if transponder operable.
- Light signal steady green
- From tower to aircraft on ground: cleared for takeoff. To aircraft in air: cleared to land. Used when radio communication fails.
- Light signal flashing green

- Monitor instruction
- ATC instruction to listen on a frequency without transmitting, e.g., 'MONITOR ATIS 127.2'. Read back frequency.
- Transmit blind
- Procedure used when unable to establish two-way communication. Transmit message on assigned frequency in blind, stating 'TRANSMIT BLIND'.
- SELCAL
- Selective calling system using tones to alert specific aircraft. If SELCAL received, contact ATC on assigned frequency.
