1 Fmgs And Its Rnav Impact
According A320 Mmel , One Fmgc ( One Fms ) U/s Implies That The Fllight Remains Within Radio Aids Coverage (regardless The Installation Of Gps)
Does This Mean That The Flight Has To Remain Out Of Rnav Airspace I.e. Must Fly Conventional Routes?
\i Do Understand That This Mmel Does Not Include B-snag Impact On Rnav .also I Know That The Fcom States That One Rnav Sys ( One Fmgs With One Vor/dme Or With One Gps ( Required For Fms Update) Is Sufficient For Flying B-rnav In Europe.
Or Does This Mean That I Have To Check The All The Route Is Under Vor Signal Coverage By Roughly Dividing The Distance Between Any 2 Vor's By 120 Nm Or Use A More Specific Vor Equation Coverage According Fl But What About Environment ...
Sorry I Am Confused,pls Help
