About the exam

A flight navigator certificate is the FAA certificate for a crewmember who navigates the airplane by dead reckoning, celestial observations and radio aids. Air carriers once needed navigators on long overwater routes; with inertial and satellite navigation almost no U.S. civil operation needs one today, and the test is taken by very few people. It is still offered: the Flight Navigator (FNX) test is on the FAA testing matrix revised September 25, 2026. Expect classic navigation — celestial, dead reckoning, grid and pressure pattern methods — rather than modern avionics, and confirm with PSI before you book in case a test center can't schedule it.

FNX has 80 multiple-choice questions in 3 hours. Every question has three answer choices, and you need 70% to pass. You test on computer at a PSI test center with a photo ID and an FAA Tracking Number (FTN) from IACRA. No instructor endorsement or other authorization is needed for a first attempt, and the testing matrix lists no minimum testing age, though the certificate itself needs age 21, English proficiency and a second-class medical (63.51). A passing result is valid for 24 calendar months (63.53). After the test you still need 63.55 experience — an approved course or 200 hours of flight navigation with day and night celestial fixes — and a practical test in dead reckoning, celestial and radio navigation.

Our practice covers every area with original questions mapped to the 63.53 knowledge areas, with step-by-step worked solutions for every calculation — wind triangle, point of no return and equal-time point, arc to time, LHA and intercept from almanac and Pub 249 extracts, grid heading and convergence, and Bellamy drift from D-values. Add flashcards for regulations, projections and celestial terms, worked case walkthroughs that plot a fix from start to finish, illustrated guides to the navigational triangle and chart projections, and timed practice tests at the real length — 80 questions in 3 hours — with a score.

Questions built on the navigator knowledge areas

Every question is original and tagged to a 14 CFR 63.53 flight navigator knowledge area — three choices like the real test, with almanac and Pub 249 extracts, plotting problems and upper-air charts described in text.

Hints and worked solutions

Reveal the rule, reference or formula behind the question when you're stuck. Every answer has the full rationale, and every calculation — wind triangle, LHA and intercept, grid heading, Bellamy drift — is solved step by step.

Adaptive practice

Questions steer toward your weakest areas, weighted like the real test, and get harder as you get stronger.

Timed practice tests

Full-length tests at the real pace — 80 questions in 3 hours — with a pacing indicator, full review and a percent score against the 70% pass mark.

Flashcards, walkthroughs and guides

Flashcards for Part 63 rules, celestial terms and chart projections, worked case walkthroughs that take a sight from almanac to plotted fix step by step, and interactive illustrated guides you explore hotspot by hotspot.

Test at home or at a center

FNX is scheduled and taken through PSI, the FAA's knowledge-testing provider. Get your FAA Tracking Number (FTN) in IACRA, then choose a PSI test center and time — no endorsement is needed for a first attempt. Because so few people take FNX, confirm with PSI that your center can deliver it. Remote testing is not offered for FAA airman knowledge tests.

At a PSI test center

  • Book through PSI's FAA scheduling site; the fee is paid to PSI, not the FAA — about $175 at PSI (confirm when you book).
  • Bring a current government-issued photo ID that meets FAA identification rules and your FAA Tracking Number (FTN).
  • Almanac, sight-reduction, chart and weather material appears in the question or as a figure supplied at the center.
  • You may use an FAA-approved flight computer and calculator under the test center's rules; PSI's testing system also includes an on-screen E6B.

Before you book

  • No instructor endorsement or written authorization is required for a first FNX attempt.
  • Plan the whole path: the certificate needs age 21, a second-class medical, 63.55 experience (an approved course, or 200 hours of flight navigation with day and night celestial fixes) and a practical test.
  • Brush up on the classic tools — the Air Almanac, Pub 249 sight-reduction tables and plotting charts — since the test is built on them.
  • If you fail, you wait 30 days to retest unless a certificated flight navigator or ground instructor signs a statement that they gave you additional instruction in each failed subject (63.59).

Exam-day game plan

How to walk in ready — and how to pace 80 questions in 3 hours.

Pacing checkpoints

Our timed test uses the real length and time — 80 questions in 3 hours — as one block of single-answer, three-choice questions. Almanac and sight-reduction extracts, charts and weather products are reproduced as described text, tables or simple diagrams — not official FAA or government publications.

20questions0:45
40questions1:30
60questions2:15
80questions3:00

The week before

  • Take one full-length timed practice test 4–7 days out, then shorter sets and rest.
  • Drill the routines until they're automatic: arc to time, GHA to LHA, Hc and intercept, toward or away.
  • Rehearse grid and pressure pattern problems with the sign conventions written out — hemisphere, east or west longitude, and which way drift goes.
  • Confirm your PSI appointment, your FTN, your ID and the flight computer and calculator you'll bring.

During the test

  • Pace yourself at about 2 minutes 15 seconds a question — sight-reduction and plotting problems take longer, recall questions much less.
  • Write down every input with its sign before you compute — east or west, north or south, toward or away.
  • Check time zones and dates when converting to UTC — a day change hides in many celestial problems.
  • Watch for EXCEPT and NOT — they flip what you're looking for.
  • Mark hard questions, answer every one and come back if time allows — there's no penalty for guessing.

Keep your head

  • A few nerves sharpen focus. If you freeze, take three slow breaths and reread the question.
  • With three choices, ruling out one wrong answer leaves you a coin flip at worst.
  • You need 56 of 80 — a few long celestial problems won't sink you.

After you test

  • You get your Airman Knowledge Test Report at the test center; it shows your score and the learning statement codes of any knowledge areas you missed, and your examiner reviews them before the practical test.
  • A passing result is valid for 24 calendar months — complete the flight navigator practical test within that window or retake the knowledge test.
  • Next comes the practical test under Appendix A to Part 63 — a ground test of star identification and celestial observations and a flight test of at least 4 hours navigating by dead reckoning, celestial means and radio aids.
