Standard Words That Carry Exact Meaning

Cut These — They Mark You As New

AIM 4-2-1(c): jargon, chatter, and CB slang have no place in ATC communications.

Phonetic Alphabet — AIM 4-2-7

Figures — AIM 4-2-8 / 4-2-9

Say digits individually. 3=TREE · 4=FOW-er · 5=FIFE · 9=NIN-er · 0=ZE-RO. Thousands: "one thousand five hundred." Altimeter/freqs digit-by-digit. Runway "two niner right."

Your Callsign — AIM 4-2-4

Initial contact: aircraft type or "Helicopter" + full N-number, dropping the "N": Helicopter Seven Zero Six Juliet Juliet (or Robinson Seven Zero Six Juliet Juliet).

After ATC abbreviates (prefix + last three: "Six Juliet Juliet"), you may use the short form too. Don't shorten it yourself until they do.

The Tape-Recorder Habit, Fixed

You don't repeat everything. You read back the items a wrong number could kill you on, plus your callsign — and acknowledge the rest.

MUST = required (AIM 4-3-18, FAA Order 7110.65). SHOULD = strong recommendation (AIM 4-4-7). Always include your callsign; read back in the same order given.

Trim It Down — Worked Examples

Takeoff clearance

Drop the wind (info, not an instruction). Keep runway + clearance + your turn.

Pattern entry

Hold short (the one you can't shortcut)

The runway name in a hold-short readback is non-negotiable. If you omit it, expect ATC to ask again.

Torrance (KTOA) Departure → Practice Area → Return

Class D under the SoCal/LAX Bravo shelf. The handoff chain is ATIS → Ground → Tower → SoCal → (reverse on return). Tap each step. Frequencies left blank — fill in current ones off the chart/ATIS; runway "two niner right" is the typical calm-wind assignment, but always use what ATIS/Tower gives.

Verify all frequencies and the active runway every flight. Sources: AIM 4-1-13 (ATIS), 4-2-3, 4-3-2, 4-1-18 (flight following), 91.129 (Class D).

Towered Field — Full Sequence

Outbound: ATIS → Clearance Delivery (if present) → Ground (taxi) → Tower (takeoff).
Inbound: ATIS → Tower (pattern/landing) → Ground (taxi to parking).

Establish two-way before entering Class D: when the controller says your callsign, you're "established." If they say "[callsign] standby" — you ARE established. If they say "aircraft calling, remain clear of Class Delta" — you are NOT; stay out.

AIM 4-3, 14 CFR 91.129.

Non-Towered / CTAF — AC 90-66C

No one to ask permission; you self-announce on the CTAF. Same Four W's, then repeat the airport name at the end:

• Monitor CTAF within 10 miles; announce inbound 8–10 miles out.
• Announce at entry, downwind, base, final, and when clear of the runway.
• Never "any traffic please advise."
• Helicopters/rotorcraft may fly a lower pattern (~500 ft AGL) and should avoid the fixed-wing flow.

AC 90-66C (2023); AIM 4-1-9. The FAA does not regulate pattern ENTRY, only pattern FLOW — observe and conform to traffic already established.

What Each Airspace Requires Of Your Radio

The "magic words": callsign = cleared to enter C/D. "Cleared into the Bravo" = the only entry into B. 14 CFR 91.129/91.130/91.131; AIM 3-2.

VFR Flight Following (Radar Advisories)

A service, not a clearance — provided workload permitting. Request from approach or center:

They'll assign a squawk and say "radar contact." You still see-and-avoid; you must report leaving their frequency. To end it: "terminate flight following, Six Juliet Juliet."

AIM 4-1-18 (Terminal Radar Services for VFR), 4-1-15.

Helicopter Phraseology — AIM 4-3-17

The AIM gives helicopters their own procedures at towered fields, recognizing your ability to operate off taxiways, ramps, and non-movement areas.

• Lead with "Helicopter" on first callup so ATC plans around fixed-wing flow.
• You are best placed to judge downwash — say "unable" if a route risks parked aircraft or people.
• Expect to be routed clear of the fixed-wing pattern to cut everyone's delay.

AIM 4-3-17; Helicopter Flying Handbook (FAA-H-8083-21B), heliport/airport operations. Rotor downwash hazard: AIM 7-3-7.

Distress & Urgency

MAYDAY, MAYDAY, MAYDAY — distress; grave, imminent danger (engine failure, fire). PAN-PAN, PAN-PAN, PAN-PAN — urgency; a problem but not yet grave.

Then: who, what, where, intentions. Guard frequency 121.5. Squawk 7700.

AIM Chapter 6; "aviate, navigate, communicate" — fly first.

Transponder Codes — AIM 4-1-20

Lost Comms (Radio Failure)

Squawk 7600. At a towered field, watch the tower for light gun signals and acknowledge by rocking the wings (day) / flashing landing light (night). VFR: proceed to land using light signals.

Light Gun Signals — AIM 4-3-13

AIM 4-2-13 (transmitter/receiver inoperative), 6-4-1; 14 CFR 91.185 (IFR). PHAK Airport Operations chapter has the same table.
