ICAO Listening Practice Test 1 – Radiotelephony Audio Comprehension & Transcripts

ICAO Listening Practice Test 1

Aeronautical listening comprehension is one of the most demanding components of the ICAO Language Proficiency Assessment (Doc 9835, Annex 1, and Annex 10). During the listening examination, candidates are evaluated on their ability to understand authentic, unscripted, and context-dependent radio transmissions delivered at natural operational tempos, containing regional accents, background acoustic noise, radio distortion, and non-routine operational complications.

To achieve ICAO Level 4 (Operational), Level 5 (Extended), or Level 6 (Expert), candidates must accurately extract critical numerical parameters, identify the nature of in-flight abnormalities, distinguish between similar call signs, and summarize tactical ATC clearances. This full-length practice test consists of five realistic test sections with complete audio scripts, multiple-choice questions, short-answer tasks, and detailed answer keys with explanations.

1.2	What initial flight level and squawk code are assigned?	FL110 and Squawk 4321.
1.3	Which ground frequency must the crew contact for pushback approval?	121.800 MHz (one two one decimal eight).

Section 2: En-Route Technical Malfunction & System Degradation

Listen to the transmission between Lufthansa 408 and Zurich Radar regarding an unexpected hydraulic failure during high-altitude cruise:

Audio Script 1.2: Hydraulic Yellow System Leak

Pilot (DLH 408): "Zurich Control, Lufthansa fow-er zero eight, PAN-PAN, PAN-PAN, PAN-PAN. We have experienced a sudden drop in yellow hydraulic system pressure and quantity is indicating zero. Flight controls are operating in alternate law. We request stop climb at flight level two eight zero and a straight-ahead heading for five minutes to run our electronic centralized aircraft monitor procedures."

ATC (Zurich Control): "Lufthansa fow-er zero eight, Zurich Control, PAN-PAN acknowledged. Maintain flight level two eight zero, fly present heading zero niner five, clear of all traffic. Advise when ready to state your intentions."

Question #	Comprehension Prompt	Official Test Answer
2.1	What alert prefix was declared by the flight crew?	`PAN-PAN` (Urgency state).
2.2	Which aircraft system has failed completely?	The yellow hydraulic system (pressure dropped, quantity zero).
2.3	What flight control status is the aircraft currently in?	Alternate Law.
2.4	What initial tactical request did the pilot make?	Stop climb at FL280 and maintain straight-ahead heading for 5 minutes.

Section 3: Severe Weather Encounter & Tactical Rerouting

Listen to the coordination exchange between Speedbird 224 and Milan Area Control as the aircraft navigates around convective thunderstorm cells:

Audio Script 1.3: Convective Storm Deviation

Pilot (BAW 224): "Milan Radar, Speedbird two-two-fow-er, we have active cumulonimbus clouds with severe lightning directly across our route at thirty miles. We request an immediate heading deviation twenty-five degrees left of track for twenty nautical miles, maintain flight level three six zero."

ATC (Milan Radar): "Speedbird two-two-fow-er, left heading deviation approved, due to military danger area Lima five eight active to the north, do not exceed thirty miles left of track. Report when clear of weather and resuming own navigation."

Pilot (BAW 224): "Heading deviation left approved, maximum thirty miles left due to danger area Lima five eight, will report clear of weather, Speedbird two-two-fow-er."

Question #	Question Prompt	Detailed Answer Key
3.1	What meteorological hazard is the crew avoiding?	Active cumulonimbus (CB) clouds with severe lightning.
3.2	What specific heading offset did the crew initially request?	25 degrees left of track for 20 nautical miles.
3.3	What airspace constraint did the controller impose?	Do not exceed 30 miles left of track due to active military danger area L58.

Section 4: Medical Incapacitation & Emergency Diversion

Listen to the transmission regarding an acute in-flight medical event requiring an emergency descent and diversion:

Audio Script 1.4: In-Flight Heart Attack & Priority Diversion

Pilot (AFR 819): "Marseille Control, Air France eight-one-niner, we are declaring an urgency situation. We have an elderly male passenger suffering severe symptoms of a heart attack in the cabin, unassisted by portable oxygen. We request immediate diversion to Lyon Saint-Exupéry, descent to flight level one zero zero, and an ambulance with medical doctor standing by at the gate upon arrival."

ATC (Marseille Control): "Air France eight-one-niner, roger urgency, cleared direct to waypoint MOZAC, descend immediately flight level one zero zero. Lyon airport notified, ambulance and paramedic medical team will be positioned at parking stand Hotel three."

Question #	Comprehension Task	Correct Test Response
4.1	What is the nature of the passenger's medical condition?	Suspected acute myocardial infarction / heart attack (unassisted by portable oxygen).
4.2	Which alternate airport has been selected for the emergency diversion?	Lyon Saint-Exupéry (direct waypoint MOZAC).
4.3	What specific ground medical services were confirmed by ATC?	An ambulance and paramedic medical team standing by at stand H3.

Section 5: Distress Declaration – Engine Flameout & Minimum Fuel

Listen to the final high-stress emergency communication involving an uncommanded engine shutdown and critical fuel endurance:

Audio Script 1.5: Dual Failure Distress Call

Pilot (KLM 602): "Shannon Control, KLM six-zero-two, MAYDAY, MAYDAY, MAYDAY. Engine number two suffered an uncontained flameout passing flight level three zero zero. We are unable to maintain altitude and are drifting down to flight level two zero zero. Furthermore, due to asymmetric burn and earlier diversion holding, we are declaring MAYDAY FUEL with twenty minutes endurance remaining. Request immediate vectors for straight-in approach runway two-four."

ATC (Shannon Control): "KLM six-zero-two, Shannon Control, MAYDAY acknowledged. Turn right heading one eight zero, descend immediately to three thousand feet, QNH one zero zero fow-er. You are cleared for straight-in ILS approach runway two-four, number one for the airport, all departures held."

Question #	Comprehension Objective	Model Scoring Answer
5.1	What happened to engine number two?	Suffered an uncontained flameout at FL300.
5.2	What drift-down altitude did the crew establish?	FL200 (flight level two zero zero).
5.3	Why did the crew declare `MAYDAY FUEL`?	Asymmetric burn and earlier holding reduced remaining fuel endurance to 20 minutes.
5.4	What initial descent and heading vector did ATC issue?	Turn right heading 180°, descend immediately to 3,000 ft on QNH 1004.
