Within MUAC free route airspace, aircraft operators are able to flight plan direct routes freely, while obeying the corresponding times of availability:
- from FRA Horizontal Entry Point (E), Departure Connecting Point (D) and FRA Intermediate Point (I)
- to FRA Horizontal Exit Point (X), FRA Arrival Connecting Point (A) and FRA Intermediate Point (I)
- by filing flight plan direct or via one or several FRA Intermediate Points.
Filing of unpublished points, defined by geographical coordinates or by bearing and distance, is not permitted in flight plans within the MUAC FRA area.
Within MUAC FRA, DCT segments shall not be planned closer than 2.5 nautical miles (NM) to the MUAC FRA lateral border.
Except for segments defined in ATS Routes, RAD Appendix 4 and Standard Instrument Departure (SID)/ Standard Instrument Arrival (STAR):
- lateral entry and exit to/from MUAC FRA shall be planned using the published FRA Horizontal Entry and FRA Horizontal Exit points only;
- vertical entry and exit to/from MUAC FRA shall be planned using the published FRA Departure and FRA Arrival Connecting points only;
- the planning of DCT segments that are partially outside the vertical and lateral limits of MUAC FRA (re-entry segments) is not allowed;
- the planning of DCT segments across the MUAC FRA border (cross border DCT) is not allowed, except to/from those FRA relevant and significant points, located outside the MUAC AoR as depicted in the MUAC FRA Index Chart.
