Need help with these acronyms

[Googles]

I was running through Reddog’s checklist and found some acronyms I need someone to clarify for me:

MFL Main Fault List?
HUD/ASHM
OBOGS - Onboard Oxygen System?
IF CHECKS - I assumed this meant In-Flight but we’re still taxying at this phase.
U/C
PFD

Also regarding Aerial Refueling:
Sensors - Check Nose Cold - what’s meant by this?

Thank you.
