B777 LNAV vs LOC
Reading the Normal Procedures chapter in Vol 1 regarding IAP using VNAV .
Can you use LNAV for a LOC approach and if the answer is no can someone explain why not. Also the Vol 1 Chapter SP - "RNP" states that the FMCS meets the requirements of a multi-sensor RNAV system when RADIO or GPS is updating, and in this configuration the FMCS may be used for ENR, TERM OPS and IAP Navigation - excluding ILS, LOC, LOC-BC,LDA,SDF,MLS. In this case can you explain why LNAV is mentioned so many times in Vol 1 IAP using VNAV.
Thanks
