How it works
From first call to ICAO certificate in 4 steps.
Fixed-bid program plan
You receive a written training plan within 1 business day — duration, number of sessions, total cost, target certification date. No retainers. No surprises.
8 to 16 weeks of live coaching
Two 60-minute live sessions per week + 3 hours of guided self-study. Cockpit-realistic scenarios, real ATC tape practice, plain-language drills for non-routine situations.
OPI mock + certification
Mid-program and end-of-program mock OPI assessments, scored by an independent ICAO-trained evaluator. Pass on first attempt or free remediation until you do.
Fixed-bid quotes
One conversation, one written plan, one fixed bid.
Every aviation English engagement is custom-quoted around your starting Level, your timeline, and the size of your fleet. Tell us how many pilots, what their current ICAO Levels are, and when they need to certify — you receive a written training plan and a fixed-fee proposal within one business day.
Who we train
Built around the radiotelephony cockpit, not a classroom.
Commercial pilots
Pilots transitioning from regional to international routes, pilots re-certifying after years out of the cockpit, and pilots whose first language is not English and need to demonstrate Level 4 for their first international type rating.
Air traffic controllers
Tower, approach, and en-route controllers preparing for ICAO certification or recertification. Heavy focus on non-routine traffic situations, weather emergencies, and pilot-controller miscommunication recovery.
Cabin crew & lead flight attendants
Senior cabin crew operating on international routes who need to handle passenger care, medical incidents, security situations, and crew coordination in English under operational pressure.
Aviation training departments
Airline and operator training divisions standardizing English proficiency across pilot rosters. Per-pilot assessment reports, cohort-level analytics, and aggregated compliance documentation for regulators.
Flight operations & compliance teams
Operations managers preparing fleets for IOSA, IS-BAO, or ICAO Annex 1 audits. Documented training records, assessment certificates, and recertification schedules for each pilot under their authority.
Aviation universities & CFIs
Flight schools and CFIs preparing student pilots for international commercial routes. Curriculum integrates with FAA Part 141 and EASA ATPL training schedules.
What we deliver
Every ICAO criterion, every session.
Six-criterion structured curriculum
Every session works against ICAO Doc 9835 (Manual on the Implementation of ICAO Language Proficiency Requirements): pronunciation, structure, vocabulary, fluency, comprehension, and interactions. No criterion gets skipped. Progress reports tag improvement against each axis individually.
Plain-language vs aviation phraseology
ICAO Level 4 isn't just about standard radiotelephony phraseology — it's about plain language when the situation breaks down (unscheduled landings, medical emergencies, equipment failure, weather diversions). Most of every session is plain-language practice in cockpit-realistic scenarios.
Mock OPI assessments
Mid-program and end-of-program OPI-style (Oral Proficiency Interview) mock assessments scored by independent ICAO-trained evaluators. Recorded for self-review. Results delivered with a six-axis criterion breakdown and a remediation plan for any criterion under Level 4.
Live cockpit/tower simulation
We don't just role-play — every session includes ATC tape analysis, real radiotelephony audio (from public NASA ASRS reports and similar), and live read-back exercises. Pilots practice with controller-side audio playing in their headset.
Schedule that fits flight rotations
Standard cadence is 2 × 60-minute live sessions per week + 3 hours of guided self-study. Sessions are typically scheduled in the same morning slot 2–3 days per week so pilots can preserve flight rotations. Recordings of every live session are available within 24 hours.
Cohort or 1:1
1:1 coaching for individual pilots or small cohorts (3–6 pilots) for airline training programs. Cohort programs include team simulation exercises (multi-crew coordination, declared emergencies). Per-pilot reporting in both formats.

Why airlines book us back for the next class.
Built by linguists with cockpit time
Our aviation English specialists have flight-deck or tower experience plus linguistic credentials. We don't teach pilots from a generic ESL textbook — we teach from real ATC tapes, real NASA ASRS reports, and the same phraseology your fleet uses every day.
Per-criterion scoring you can audit
Every assessment report breaks performance down by the six ICAO criteria with examples, audio clips, and remediation actions. When your fleet auditor asks 'why is this pilot at Level 4 instead of Level 3?' — the answer is documented.
Documented for IOSA / IS-BAO audits
Training records, assessment certificates, recertification schedules, and audit-ready compliance reports. Auditors get the documentation they want; you don't dig through PDFs to find it.
Recertification scheduling built in
ICAO requires recertification every 3 years at Level 4 (every 6 years at Level 5, never at Level 6). We track each pilot's certification expiration and schedule the recertification cycle automatically. You don't manage the calendar.
Tier-1 carrier-grade confidentiality
All training audio, mock assessment recordings, and progress reports are stored under per-engagement confidentiality agreements. Per-airline data segregation. Training data never used for marketing materials without explicit written consent.
Worldwide delivery, US billing
Pilots train from anywhere — Manila, Lagos, Doha, Reykjavik. Billing is US-based under DUNS 130473444, NAICS 541930, ideal for US carriers and DoD contracts. Multi-currency invoicing available for international operators.
Frequently asked
Common questions
How long does it take to reach ICAO Level 4?
Most pilots starting at Level 3 reach Level 4 in 8–12 weeks with our intensive sprint program (2 live sessions per week, 3 hours of guided self-study). Pilots whose strong-suit areas already test at Level 4 but whose pronunciation or interaction scores are at Level 3 typically reach Level 4 in 6–8 weeks.
What's the difference between Level 4, Level 5, and Level 6?
Level 4 (Operational) requires that pilots and controllers can communicate effectively in routine and non-routine work situations. Level 5 (Extended) is a broader, more flexible command of English including unusual situations. Level 6 (Expert) is essentially native-speaker proficiency, with no recertification required. Most international operators require Level 4 minimum; some require Level 5 for specific routes.
Do you offer ICAO assessments, or only training?
Both. We administer ICAO-compliant Oral Proficiency Interviews (OPI) as standalone assessments for pilots and ATCs who need an official Level rating without a full training program. Mock assessments are included with every training program. Final certification assessments are issued by independent ICAO-trained evaluators.
Can you handle a whole pilot cohort for an airline?
Yes. We've delivered cohort programs for 6–50 pilots at a time. Cohort programs include team simulation exercises (multi-crew CRM, declared emergency drills), per-pilot reporting, and aggregated compliance documentation suitable for IOSA, IS-BAO, and ICAO Annex 1 audits.
What does an Aviation English program cost?
Every engagement is custom-quoted around the pilot's starting ICAO Level, the timeline, and the size of the fleet. Tell us how many pilots, their current Levels, and when they need to certify — we'll respond with a written training plan and a fixed-bid proposal within one business day.
Is recertification included?
Recertification is a separate engagement. We track each pilot's certification expiration date and schedule the recertification assessment 90 days before expiry, so there's no gap in your fleet's compliance documentation. Recertification typically requires a single OPI assessment unless the pilot needs remediation training to maintain Level 4.
