Model 1 (or M1) is the last filed flight plan data, as filed by the airlines with vertical profile and time calculated by CFMU
optimizes capacity of the entire European network of infrastructure and services and helps contain delays.
These improvements reflect the initial benefits of RVSM implementation and other accompanying measures taken by European ANSPs (Air Navigation Service Providers) and the CFMU
(Central Flow Management Unit).
The plans are produced by the CFMU
(Central Flow Management Unit) that was set up in 1988 to (i) receive, validate, correct and distribute all flight plans from airline operators in the European Civil Aviation Conference area (comprising 38 European states), and (ii) optimize the use of that airspace to avoid overloads whist minimizing delays.
Applying CDM creates a common situational awareness and predictability between ATM, the airport, aircraft operators, CFMU
, ground handlers and other service providers.
Introduction of optimized route planning in Europe, ETOPS capabilities and CFMU
validation continue to build on the successful framework of Jeppesen FlitePlan Online, which allows worldwide flight plans to be intuitively designed and filed in less than one minute and eliminates multiple-step data entry.
