Thanks engfireleft
I meant radial........I have that getting to grip, but.......
I write for you the procedure for rnp10 (is the same for 4 or 5 but with different number).....
if a manual entry of accuracy is desired, the flight crew must manually enter: for rnp 10, enter 10 NM or use the radial equivalent to 10 NM XTK accuracy that is 12.2 NM.
