The answers you want before you start the engine.
Runways and surfaces
Every runway with its designator, length, width, surface and lighting — longest first, so you know in two seconds whether you fit.
Frequencies
Tower, ground, information and ATIS as published, in one block you can read on the ground before you taxi.
Fuel, fees and PPR
AVGAS, MOGAS, Jet A-1, what landing costs, and whether the field wants a phone call first. Where a field has none of something, the page says so.
The official chart, one click away
A direct link to the current AIP entry for the field, per country, always to the authority's own page.
The area around it
Every airfield within roughly 100 miles by name and distance, plus the nearest sensible alternates.
Notes from pilots who landed there
Runway condition, where to park, which café is open on a Monday — written by the pilots who found out. Free to read.

Flying in Europe
Country guides covering the paperwork, the radio, the fees and the habits that catch visiting pilots out.
Read the guides →Pilots, clubs and the forum
Pilots here keep a home field, a map of everywhere they've flown and the types they fly. Clubs and flight schools have their own pages, and the forum is where the questions get answered. All of it readable without an account.
Look around →Who keeps this current
CAVOK is built and maintained by Stephan Uhrenbacher, a European GA pilot who previously built Qype and FLIO. Reference data comes from OurAirports and from each country's own AIP. Everything beyond that is checked by hand, field by field, and pilots add the rest — notes, photos, fuel prices and landing fees. Every page has a report link: if something is out of date, one click tells us.
Reference only. Always verify against the current official charts before flight.
