there are three missions in the package
normal (for when you just wanna remember how things go)
just follow waypoints or TACAN and use ILS when in-range
hard (a challange)
use waypoints or TACANto get in-range for ILS. dont be afraid to use autopilot. only trim for your payload. wind directions change depending on the altitude.
suicide (a really hard challange. but if you're used to(or want to get used to) getting completely ruined planes home this is the worst case system wise)
the only "valid" tactic would be to dip below the clouds and VFR it
