All commands

Keep this page open while you play. Nothing here is explained — for that, use Learn to control. For the same instructions by mouse, use Mouse and keys.

Applies to VoiceATC Simulator 0.6.1.24 — the current stable release. Anything marked New in … is not in it yet.

• [brackets] — information you provide (callsign, waypoint, value).
• (parentheses) — optional words. You may say them or skip them.
• Italics — an example of what you actually say.

Beginner Start here. No air traffic control knowledge needed.

Standard Everyday controlling. Learn this after the basics.

Advanced Fine control. For experienced controllers.

Lateral — where it flies

Level	You say	Example	What happens
Beginner	[Callsign], (turn) left/right heading [heading]	Iberia one two three four, turn right heading one three zero	Turns onto that heading and holds it.
Beginner	[Callsign], continue present/current heading	Iberia one two three four, continue present heading	Keeps its current heading.
Beginner	[Callsign], (fly) direct [waypoint]	Iberia one two three four, fly direct RULOS	Flies straight to the waypoint.
Standard	[Callsign], hold over [waypoint] (as published)	Iberia one two three four, hold over NEPAL	Flies the published hold over that fix.
Advanced	[Callsign], after [waypoint], (fly/turn) heading [heading]	Iberia one two three four, after RULOS, fly heading one three zero	Turns onto the heading after passing the fix.
Advanced	[Callsign], after [waypoint], (fly) direct [waypoint]	Iberia one two three four, after CASPE, fly direct LOBAR	Proceeds to the second fix after the first.

• Heading, direct-to and hold are mutually exclusive — a new one replaces the old.
• after [fix] defers only the next lateral instruction. Everything else in the call applies now.
• Not in 0.6.1.24 In an after-direct clearance, the first waypoint must be ahead on route. The second can be any known waypoint.
• Say hold explicitly. “Over NEPAL” alone does not start a holding pattern.

After vectoring, direct-to still recognizes every fix ahead in the aircraft’s stored flight plan. Not in 0.6.1.24

Altitude

Level	You say	Example	What happens
Beginner	[Callsign], climb/descend (flight level/altitude) [value] (feet)	Iberia one two three four, climb altitude five thousand feet	Climbs or descends to that level. Add unrestricted to cancel altitude restrictions.
Standard	[Callsign], expedite (climb/descent) (to) [value] · [Callsign], expedite (climb/descent), climb/descend [value] · [altitude clearance], expedite · expedite (climb/descent)	Iberia one two three four, expedite descent, descend five thousand feet	Increases the climb or descent rate until level-off. Naming a level in the same call clears to it as well, whether you name it once or repeat the verb. Not in 0.6.1.24
Standard	[Callsign], resume normal rate (of climb/descent) · expedite no longer required	Iberia one two three four, resume normal rate of descent	Back to the normal climb or descent rate.
Advanced	[Callsign], cross [route fix] at [altitude] · to be level by [route fix]	Iberia one two three four, cross BAVAD at flight level one zero zero	Reaches that level by the named forward route fix, then holds it.
Standard	[Callsign], QNH [value] (hectopascals)	Iberia one two three four, QNH one zero one six	Pilot sets that QNH.
Standard	[Callsign], altimeter [value]	Iberia one two three four, altimeter two niner niner two	Pilot sets that altimeter value.

• Give a plain value: the game picks feet or flight level from the transition altitude.
• A new plain altitude clearance cancels an active expedite.
• A crossing fix must be ahead on the aircraft’s route, and the crossing must be achievable, or it is refused.
• QNH for hectopascals, altimeter for inches.

Speed

Level	You say	Example	What happens
Beginner	[Callsign], speed [value] (knots)	Iberia one two three four, speed two two zero knots	Flies that speed until told otherwise.
Standard	[Callsign], speed mach decimal [value]	Iberia one two three four, speed mach decimal seven eight	Flies that Mach number.
Standard	[Callsign], resume managed speed · speed at your discretion	Iberia one two three four, resume managed speed	Hands speed control back to the aircraft.

• Say the Mach digits one at a time after mach decimal — “mach decimal seven eight” is Mach 0.78.
• resume managed speed can make the aircraft speed up or slow down at once.

Procedures and approach

Level	You say	Example	What happens
Standard	[Callsign], cleared [STAR] arrival	Iberia one two three four, cleared ADUXO two delta arrival	Flies that arrival route.
Standard	[Callsign], cleared [STAR] arrival, expect runway [runway]	Korean Air four two six, cleared OLMEN two echo arrival, expect runway three four right	Flies the runway-specific arrival branch and prepares the matching approach. Does not clear the approach.
Standard	[Callsign], expect runway [runway]	Iberia four nine india november, expect runway three two right	Re-plans the approach ahead only; never clears it.
Advanced Not in 0.6.1.24	[Callsign], expect [published visual name] (approach) runway [runway]	Iberia one two three four, expect Park Visual runway three one	Remembers the named visual; changes no flight path.
Standard	[Callsign], cleared [transition] transition	Iberia one two three four, cleared RULOSO one whiskey transition	Flies that feeder toward the approach.
Standard	[Callsign], cleared (ILS) approach runway [runway]	Iberia one two three four, cleared ILS approach runway two four left	May join and fly the approach.
Standard	[Callsign], cleared RNAV/RNP approach runway [runway]	Iberia one two three four, cleared RNAV approach runway two two	Flies the published RNAV approach, curved final segments included.
Advanced	[Callsign], cleared RNAV [letter] runway [runway]	Iberia one two three four, cleared RNAV zulu runway two two	Picks that chart variant where a runway has more than one RNAV.
Standard Not in 0.6.1.24	[Callsign], cleared [GLS/GPS/LOC/LOC back course/LDA/VOR/VOR DME/VORTAC/NDB/NDB DME] approach runway [runway]	Iberia one two three four, cleared VOR DME approach runway two five left	Flies that exact published civil approach.
Advanced	[Callsign], via [entry fix], cleared (ILS) approach runway [runway]	Iberia one two three four, via LESBA, cleared ILS approach runway two four left	Flies the feeder fix, then the approach.
Standard Not in 0.6.1.24	[Callsign], report runway [runway] in sight	Iberia one two three four, report runway two four left in sight	Requests the matching visual sight report.
Standard Not in 0.6.1.24	[Callsign], report [visual reference] in sight · advise when [visual reference] is in sight	Iberia one two three four, report the Twin White Tanks in sight	Tests that source-backed target; otherwise uses the runway.
Standard Not in 0.6.1.24	[Callsign], cleared visual approach runway [runway]	Iberia one two three four, cleared visual approach runway two four left	Clears the generic managed visual path.
Advanced Not in 0.6.1.24	[Callsign], cleared [published visual name] approach	Iberia one two three four, cleared River Visual approach	Clears the named charted visual route.
Standard Not in 0.6.1.24	[Callsign], go around · execute (the) missed approach	Iberia one two three four, go around	Climbs and flies the sourced missed route.
Advanced Not in 0.6.1.24	[Callsign], go around, (fly) heading [heading], (climb and maintain [altitude])	Iberia one two three four, go around, fly heading two six five, climb and maintain three thousand	Overrides either missed guidance axis.
Advanced	[Callsign], descend via [STAR] (to/except maintain [level]) · climb via [SID] (to [level])	Iberia one two three four, descend via ADUXO two delta to flight level one zero zero	Follows the published restrictions, stopping at the level you name.

• Vectors are not an approach clearance. Say cleared approach runway [runway] to clear it.
• An arrival stops at its STAR clearance limit until a separate approach clearance is given.
• expect runway on its own re-plans an arrival at any time. It changes only the route ahead, and leaves a hold, a vector, or an after the fix turn in place.
• Say arrival for STARs and transition for approach feeders.
• RNAV and RNP are interchangeable. Variant letters are the NATO words or the bare letter: zulu, yankee, xray, whiskey, victor, uniform.
• Not in 0.6.1.24 Name the exact civil type when you need it. If that type or suffix is unavailable, the pilot refuses instead of choosing another one.
• Not in 0.6.1.24 RNP AR needs the full procedure. It rejects vectors to final.
• A visual clearance has two steps: request the sight report, then clear the visual after the aircraft reports it. A clearance sent first is refused.
• Not in 0.6.1.24 expect [published visual name] remembers only that named procedure. It changes no route, guidance or altitude and grants no authority.
• A named expectation can disambiguate a later short reference such as report the airport in sight. Explicit report runway [runway] in sight stays generic.
• Named sight references are source-backed physical targets. Seeing one airport, runway, landmark or route never counts as seeing another.
• A short natural reference may label a generic request. It never creates a landmark position or authorizes a named visual procedure.
• The immediate reply is in sight or will report in sight, followed by the callsign. The pilot never repeats the reference.
• A named forward-route visual may join a safe published segment ahead after sight is reported. It will not turn backward, skip a required arc or cross protected airspace to make the join.
• Bare go around follows the selected instrument miss or that visual’s own charted instructions. An unsourced visual needs a heading or altitude.
• A below-current go-around altitude is unable. The aircraft still climbs on the safe resolved target.
• Not in 0.6.1.24 Circling/unresolved, TACAN-only, FMS, IGS, MLS and SDF approaches remain unavailable.

Handoff

Level	You say	Example	What happens
Standard	[Callsign], contact tower / center / radar	Iberia one two three four, contact tower	Pilot changes frequency and leaves you.
Standard	[Callsign], contact [facility] (on/frequency) [frequency]	Iberia one two three four, contact approach on one one niner decimal one zero five	Uses the published frequency, reads it back and hands off.

• A facility-only handoff keeps working as before.
• If you say a frequency, it must match that facility in the current published radio data. If it was unclear, unpublished, or belongs to another facility, the pilot asks for the frequency and does not perform a facility-only handoff. Other independent instructions in the same call can still be accepted.

Corrections

Level	You say	Example	What happens
Standard	[Callsign], disregard · cancel · negative	Iberia one two three four, disregard	Cancels the last instruction, within about ten seconds.
Standard	[Callsign], negative/correction, [new clearance]	Iberia one two three four, correction, descend flight level one two zero	Applies the new clearance instead of cancelling.
Advanced	[Callsign], negative, that was for [callsign]	Iberia one two three four, negative, that was for Air Europa two zero five	Moves the last clearance to the intended aircraft.

• The undo window is about ten seconds. After that, give a new clearance instead.
• negative, that was for [callsign] moves the clearance — the first aircraft does not fly it.

Chains — several instructions in one call

Up to five instructions per transmission, spoken in the order they are flown. The pilot reads the whole chain back.

Level	You say	Example	What happens
Advanced	[Callsign], descend [value], (turn) heading [heading], speed [value]	Iberia one two three four, descend flight level one zero zero, turn left heading two seven zero, speed two one zero	Three instructions, flown in order.
Advanced	[Callsign], (fly) direct [waypoint], cleared (ILS) approach runway [runway]	Iberia one two three four, fly direct LESBA, cleared approach runway two four left	Direct to the fix, then cleared for the approach.
Advanced Not in 0.6.1.24	[Callsign], (turn) heading [heading], cleared (ILS) approach runway [runway]	Iberia one two three four, turn left heading one eight zero, cleared approach runway two four left	Flies the vector first, then arms the approach clearance.
Advanced	[Callsign], after [waypoint], (fly) direct [waypoint], cleared (ILS) approach runway [runway]	Iberia one two three four, after CASPE, fly direct LOBAR, cleared ILS approach runway two four right	After the first fix: direct, then approach clearance.
Advanced	[Callsign], after [waypoint], (fly/turn) heading [heading], cleared (ILS) approach runway [runway]	Iberia one two three four, after RULOS, turn left heading one eight zero, cleared ILS approach runway two four left	After the fix: onto the intercept heading, already cleared.

• Only one lateral instruction per chain — heading, direct-to and hold exclude each other.
• after [fix] can also prefix an altitude instruction inside a chain.
• When a vector and approach clearance share one transmission, the aircraft establishes the vector before it arms the approach. The clearance remains pending rather than turning the aircraft straight toward final. Not in 0.6.1.24

Answering the pilot

You say	When
affirm	The pilot asked you to confirm a waypoint, arrival, transition or runway and was right.
negative	It was wrong — then say the correct name.
the name again	Fastest correction: just repeat the waypoint or procedure clearly.
the whole clearance again	Also works — restate it with the right value and it is applied straight away.
NATO spelling	If the pilot asks can you spell that waypoint?, spell it — bravo india sierra bravo alpha for BISBA.

Exact NATO spelling works for real three- and five-character fixes or VORs in the current sector. Unknown identifiers still trigger clarification.

Not in 0.6.1.24

A completely different command also works as an answer — the question steps aside and the new instruction is flown. Each spoken question restarts your answer window.

Recognition rules that matter

1. Callsign first, always, then the instructions.
2. Spell unfamiliar fixes phonetically — bravo lima four six one for BL461.
3. Three instructions or fewer per call is the most reliable.
4. Say “hold” explicitly to start a holding pattern.
5. Commands only work on assumed aircraft. Otherwise COM answers SYS: The aircraft is not assumed. — middle-click the aircraft first.
