When pilots plan a move abroad, they think about the licence conversion, the type rating and the sim check. The language proficiency endorsement on the licence is the item most people forget, right up until a recruiter asks for its expiry date.
It's a small thing that can delay a start date, so here's how it works and what to check before you apply.
What the ICAO language proficiency requirement is
ICAO Annex 1 requires aeroplane and helicopter pilots, among others, to show they can speak and understand the language used for radiotelephony, to the level set out in the Annex's language proficiency requirements. Proficiency is rated on a six-level scale, and Operational Level 4 is the minimum to exercise licence privileges where those requirements apply.
The rating looks at six areas: pronunciation, structure, vocabulary, fluency, comprehension and interactions. Your overall level is the lowest of the six, not the average, so one weak area pulls everything down.
| Level | Name | What it means for your licence |
|---|---|---|
| 6 | Expert | No periodic re-evaluation required |
| 5 | Extended | Re-evaluated at intervals (see below) |
| 4 | Operational | Minimum for licence privileges; re-evaluated most often |
| 1-3 | Pre-elementary to pre-operational | Below the minimum |
How long each level stays valid
This is where authorities differ, and it's the detail that catches people out.
- ICAO recommendation: Level 4 evaluated at least once every three years, Level 5 at least once every six years. Each authority sets its own interval. (>ICAO Personnel Licensing FAQ)
- EASA (FCL.055): Level 4 every 4 years, Level 5 every 6 years, Level 6 no re-evaluation. The endorsement on the licence shows the language, the level and the validity date. (>EASA FAQ, >Easy Access Rules for Aircrew)
- UK CAA: Level 6 has no periodic re-evaluation, Level 5 every six years and Level 4 every four years. (>UK CAA)
- FAA: US certificates carry an "English Proficient" endorsement. The FAA's minimum for that endorsement is ICAO Operational Level 4, and Part 61 already requires pilots to read, speak, write and understand English. (>FAA, >AC 60-28B)
If you're moving to a region with its own authority, check its rules directly. Don't rely on what your current authority does.
Why it matters more when you change airlines
1. Dates collide. A Level 4 endorsement that's fine today can expire in the middle of a conversion, a type rating course or a probation period. Recruiters and licensing departments often ask for the validity date early.
2. The new authority may assess you itself. When you convert a licence, the new authority issues the licence and applies its own procedure for the language endorsement. Some accept existing evidence; others want their own assessment. Ask before you assume. My guide to converting your pilot licence to another authority covers the rest of that process.
3. Interviews test the same skills informally. A technical interview, a sim briefing and a group exercise all show how clearly you communicate under pressure, in a second language for many of us. Communication is one of the competencies most airline assessments look at.
How to prepare
- Check your endorsement today. Find the level and expiry date on your licence and note it next to your medical and type rating dates.
- If you hold Level 4, consider testing for a higher level. A Level 5 or 6 result means fewer re-tests and one less date to manage during a move. Only do this if you're realistically ready for it.
- Practice plain English, not just phraseology. Standard R/T phrases come easily after years of line flying. The test and the interview push into plain-language situations: describing an unusual event, explaining a decision, handling a misunderstanding.
- Rehearse explaining a non-normal event aloud. Pick an event you've handled, then explain what happened, what you considered and why you decided what you did, in two minutes, without jargon. That single skill helps in the language test, the technical interview and the direct-entry captain interview.
- Use an approved test provider. Only approved or authority-certified assessors can issue a result your licence will accept. Check the list on your authority's website.
The captain's bottom line
Language proficiency rarely decides whether you get the job, but an expired or low endorsement can decide when you start. Put the date in the same list as your medical and type rating, and if you're close to a renewal, do it before you apply, not during the move.

Frequently asked questions
What ICAO English level do airline pilots need?
ICAO sets Operational Level 4 as the minimum for pilots who use radiotelephony. EASA, the UK CAA and the FAA all use Level 4 as the minimum. Individual airlines can set a higher bar in their own recruitment.
How long is ICAO Level 4 valid?
ICAO recommends re-evaluating Level 4 at least every three years and Level 5 at least every six years. Under EASA rules (FCL.055) and UK CAA rules, Level 4 is re-evaluated every four years and Level 5 every six years. Level 6 needs no periodic re-evaluation.
Does my ELP endorsement transfer when I convert my licence?
Don't assume it does. The endorsement sits on the licence issued by your authority, and a new authority applies its own procedure. Ask the authority you are moving to how it will assess or accept your language proficiency before you plan your dates.
Do native English speakers have to take the test?
Rules differ by authority. ICAO notes that formal evaluation isn't required for people who demonstrate expert (Level 6) proficiency, but you still need the endorsement on your licence. How Level 6 is assessed is up to each authority.
