ICAO Listening Practice Test 3 – Advanced Radiotelephony & Emergency Audio Comprehension

ICAO Listening Practice Test 3

The third and final module of the advanced ICAO Listening series evaluates candidates on high-workload, complex, and safety-critical aeronautical radio communications. Under ICAO Doc 9835, Annex 1, and Annex 10 standards, candidates targeting ICAO Level 5 (Extended) and Level 6 (Expert) must demonstrate auditory precision when processing rapid multi-instruction clearances, ambiguous call signs, heavy regional accents, carrier wave step-ons, and urgent emergency declarations.

This test consists of five advanced operational audio scripts across diverse flight environments: High-Density Terminal Arrival Sequencing, In-Flight Lithium Battery Thermal Runaway, Microburst Windshear on Short Final, Dual Hydraulic Failure with Asymmetric Flaps, and Fuel Leak with Emergency Diversion. Each section contains detailed comprehension tasks, shorthand extractions, phonetic analyses, and scored answer keys with operational rationales.

ATC (Munich Tower): "Lufthansa fow-er six zero, caution severe low-level windshear reported by preceding Airbus on two-mile final, loss of twenty knots airspeed below five hundred feet, surface wind two tree zero degrees, two zero knots, gusts tree eight knots."

Pilot (DLH 460): "Munich Tower, Lufthansa fow-er six zero, WINDSHEAR ESCAPE, GOING AROUND! Onboard reactive windshear warning triggered at tree hundred feet, maximum TOGA thrust set, climbing straight ahead fow-er thousand feet."

ATC (Munich Tower): "Lufthansa fow-er six zero, roger windshear go-around. Climb straight ahead fow-er thousand feet, when passing two thousand five hundred feet turn left heading zero niner zero, contact Munich Radar on one two tree decimal niner."

Pilot (DLH 460): "Climb straight ahead fow-er thousand feet, passing two thousand fife hundred turn left heading zero niner zero, frequency one two tree decimal niner, Lufthansa fow-er six zero."
