Your AIRAC cycle
Import any Navigraph navigation database (DFD v2) and plan routes, SIDs and STARs for exactly that cycle — to match the nav data in your aircraft.
Offline flight dispatch, in seconds.
A complete SimBrief-format flight plan — route, fuel, weights, ETOPS, briefing and takeoff & landing performance — generated on your own PC for any AIRAC cycle you choose, then loaded straight into your aircraft.
Free download for Windows 10 / 11 (64-bit). iAnnouncer owners get 1 month of subscription free when they register in MyBrief.

MyBrief rebuilds a full dispatch workflow offline, with aircraft profiles calibrated against real SimBrief plans.
Import any Navigraph navigation database (DFD v2) and plan routes, SIDs and STARs for exactly that cycle — to match the nav data in your aircraft.
Search real-world schedules by flight number, airline, airport or aircraft type. One click fills a new plan with the real airports, times, aircraft and filed route.
Fetch your latest SimBrief plan, keep its aircraft and load, and rewrite the route with procedures and airways valid in your cycle — every change is listed.
Cruise level selection, step climbs, contingency and reserve policies, alternates, ETOPS, weight & balance and a full SimBrief-style dispatch briefing.
Config, flex temperature, V-speeds and maximum takeoff weight for every runway; landing distances with flap and brake comparisons.
Flip one switch and aircraft and EFBs that load from SimBrief receive the plan MyBrief just generated — no add-on settings to change.
Compare standard and supplemented navigation data of the same cycle and write the extra airports into your aircraft's navigation database.
