B777 Alternate Navigation Radio Page
Hi
In FCOM on 11.50.6, it says:
If both FMCs fail, access is by the NAV RAD key on the left and right CDUs only.
• the left CDU tunes the left radios and center ILS.
On 11.50.7, it says:
Note: ILS course and frequency must be entered on the left, center, and right ALTN NAV RADIO page.
What does it mean?
Regards
