I start with the "cold and dark" cockpit scenario (haven't hit the un-resettable siren bug) but have noticed that after going into the NAV RAD page and deleting the two NAV freqs (change the M to A) that both VORs auto-tune to the same freq all the time. Aren't they supposed to split for better DME accuracy or am I doing something wrong?

Thx!

You are not doing something wrong. VORs are are supposed to tune to the same frequency on both sides most of the time. Dedicated DME receivers that are capable of tuning to several DMEs are used for NAV position updates.

Cool. As they say you learn something new every day.

Thanks!
