Best Boeing 757 & 767 ANP Values?
 
Would anyone know what the best (lowest) Actual Navigation Performance (ANP) values are that can generally be acheived by Boeing 757s and 767s?

:ok:

I believe that with Pegasus and dual multi mode receivers you can get down to 0.1 ANP. With the standard non GPS FMS, or PIP I doubt that you can get better than 0.3 and there may be other limitations to that installation.

Have seen references to .06 ANP.

A CNN article describes an apparently smaller general ANP figure:

"Naverus's precise satellite-guided flight paths look like discrete pipelines. The routes pilots follow never vary more than 18 meters - half the wingspan of a Boeing 737 - allowing aircraft controllers to increase the number of incoming flights."

Current RNP for B757 B767 is .1.

.1 with the Pegasus as previously stated but not so with the Standard or PIP version of the FMS. You gotta have that GPS dual MMR thingy for the close work and many departures quantify that requirement.:O
