Signs, Markings, Lighting & Communications

Read the airport and talk the talk — signs, markings, lighting, radio phraseology, and light-gun signals.

By the end of this lesson you can:

1 · Signs, markings & lighting

Know mandatory (red), location (black), and direction/destination signs; runway and taxiway markings; and airport lighting (runway/taxiway edge, PAPI/VASI if used). Heliports add the ‘H’ marking, touchdown/positioning circles, and any weight/size markings. Verify the field’s specifics in the Chart Supplement.

2 · Communications

Use standard phraseology: who you are calling, who you are, where you are, and what you want. At non-towered fields use the CTAF and self-announce; helicopters often operate to spots and patterns that differ from airplanes, so make your intentions clear. Read back hold-short and runway-crossing instructions verbatim.

3 · Light-gun signals

SignalIn flight / on ground
Steady greenCleared to land / cleared for takeoff
Steady redGive way, continue circling / stop
Flashing redAirport unsafe, do not land / taxi clear of runway
Flashing white(Ground) return to starting point
Alternating red/greenExercise extreme caution

Your aircraft: radio/avionics specifics are installation-dependent — note your R44’s installed comms and how to operate them, and confirm the field’s frequencies in the Chart Supplement.
✍️ Fill in for the aircraft you fly the CTAF/tower/ground frequencies for your home field and how your R44’s radios/transponder are operated — look these up in the Chart Supplement and POH/avionics supplement and confirm with your CFI.
⚑ FLAG (Walter): the R44 is a VFR-certificated piston helicopter; confirm the aircraft/figures the student actually flies and that all numbers come from the current R44 POH.
Risk management (the “Consider”): the airport trap is a runway/heliport incursion from poor positional awareness or a misheard clearance. Read back hold-short and crossing instructions verbatim, keep a current diagram in view, and self-announce clearly at non-towered fields.
