aday-air.com is a marketplace and management platform for general aviation: a searchable registry of aircraft, aircraft for sale and for rent, pilots, technicians and parts, and the tools an owner, operator, flight school or repair shop needs to run the fleet — claims and permissions, documents, due items, POH and type data, learning material and bookkeeping.

What the platform does

  • Aircraft registry and search — hundreds of thousands of aircraft from public registries and manufacturer data, with type specifications, engines, propellers and avionics.
  • Marketplace — aircraft for sale and for rent, engines, parts, pilots and technicians. Listings are published by their owners or sellers; we also show listings found on other marketplaces with a link to the source.
  • Fleet management — verified owner claims, connections for co-owners, operators, maintenance providers, instructors and student pilots, table-level permissions, documents, due items, hours and POH data.
  • Business tools — invoicing, expenses, bank reconciliation and VAT reporting for the companies that use the platform.
  • Learning — PPL theory subjects, exam planning and regulations.

We are a technology platform. Sales, rentals and services agreed through the site are contracts between the users involved; see the Terms of Service.
