The word fields a proficiency interview actually visits. The vocabulary rating is about range and precision, and about talking around a word you cannot recall, which is what the plain English group drills.

Question 1 of 11

V-WX-01

Your colleague says: "The weather at the destination is deteriorating." What is happening to the weather?

  • It is getting worseCorrect
  • It is getting better
  • It is staying the same
  • It is changing direction

To deteriorate means to get worse over time. The opposite, getting better, is to improve. Both verbs appear constantly in weather briefings and in plain-language exchanges with ATC.

Question 1 of 11

V-WX-12

A controller passes: "Visibility 10 kilometres or more, no cloud below 5000 feet, no significant weather." Which single word from the METAR family summarises this?

  • CAVOKCorrect
  • NOSIG
  • TEMPO
  • SKC

CAVOK (cloud and visibility OK) means visibility 10 km or more, no cloud below 5000 ft (or the minimum sector altitude if higher), no cumulonimbus, and no significant weather. The near miss NOSIG means no significant CHANGE is expected: it describes the trend, not the current weather.

Question 1 of 11

V-TEC-01

The main body of the aircraft, where the passengers and cargo are carried, is the:

  • FuselageCorrect
  • Empennage
  • Nacelle
  • Fairing

The fuselage is the central body. The empennage is the tail group, a nacelle is the engine housing, and a fairing is a smooth cover that reduces drag. Empennage is the classic near miss because both words sound French and formal.

Question 1 of 11

V-TEC-12

Fluid escaping from a pipe or a seal, for example in the hydraulic system, is called a ___. (one word)

Answer leak (also accepted: leakage)

A leak is any unwanted escape of fluid or gas: a fuel leak, a hydraulic leak, an oil leak. The verb is to leak: "The left system is leaking." Being able to say what is leaking and how fast is core interview material.

Emergencies and non-routine · Set 1

Question 1 of 11

V-EMG-01

Your aircraft is in grave and imminent danger and needs immediate assistance. Which spoken prefix declares this on the radio?

  • MAYDAY, MAYDAY, MAYDAYCorrect
  • PAN PAN, PAN PAN, PAN PAN
  • SECURITE
  • EMERGENCY, EMERGENCY

MAYDAY declares distress: grave and imminent danger needing immediate assistance. The near miss is PAN PAN, which declares urgency: a serious situation that does not yet need immediate assistance. "EMERGENCY" alone is not a standard prefix.

Question 1 of 11

V-EMG-12

ATC asks: "Say souls on board." What are they asking for?

  • The total number of people on the aircraftCorrect
  • The number of passengers only
  • The number of crew only
  • The number of injured people

Souls on board means every person on the aircraft: passengers plus all crew. The trap is counting passengers only. The phrase usually comes with "and fuel remaining", asked in time, not in litres or kilograms.

Question 1 of 9

V-MED-01

A passenger has collapsed and does not respond to voice or touch. The most precise word for their condition is:

  • UnconsciousCorrect
  • Asleep
  • Unresponsive-ish
  • Tired

Unconscious means not awake and not responding. It is stronger and more precise than "not feeling well". Pairing it with what you observe ("unconscious but breathing") gives medical services exactly what they need.

V-MED-10

Hot water from the galley spilled on a passenger's hand, which is now red and blistering. The injury is a:

  • Burn (scald)Correct
  • Cut
  • Sprain
  • Sting

Hot liquid causes a scald, a type of burn. A cut is from something sharp, a sprain is a twisted joint, and a sting comes from an insect. Naming the injury type accurately guides the first aid.

Question 1 of 9

V-GND-01

A tug pushes the aircraft backwards off the stand before engine start. This operation is called:

  • PushbackCorrect
  • Rollback
  • Setback
  • Turnback

Pushback is the standard word for the tug moving you backwards off the stand. You request it from ATC or the apron service: "Request pushback." The other options are real English words but not aviation operations.

Question 1 of 9

V-GND-10

Before departure in freezing weather, a rig sprays heated fluid over the wings. This is done at the de-icing:

  • Pad (or bay)Correct
  • Pool
  • Dock
  • Booth

De-icing happens at a de-icing pad or bay, either on a dedicated area or at the stand. The fluid protects for a limited holdover time, a phrase worth using when you narrate a winter departure.

Question 1 of 11

V-PLN-01

The controller instructs you to report a point. You answer "WILCO". In plain English you are saying:

  • I understood your message and I will comply with itCorrect
  • I heard something, please repeat
  • Yes, that is correct
  • Message received, no action needed

WILCO is short for "will comply": understood AND will do it. The near miss is ROGER, which only means "I received your transmission" and promises nothing. AFFIRM answers a yes-or-no question.

Plain English vs radiotelephony · Set 2

Question 1 of 11

V-PLN-12

The controller says "MAINTAIN flight level 240". In everyday English, MAINTAIN means:

  • Keep, stay atCorrect
  • Climb to
  • Descend to
  • Repair

MAINTAIN means continue at, keep. The dictionary meaning "repair and service" (maintenance) is the trap; on the radio it never means that. "Maintain present heading" = keep flying this heading.
