Thank you for your reply.
I am asking about the weather right now at the Takeoff Airport, not the weather at Alternate Airport.
Takeoff airport reports right now “RVR 1200, 200 BKN”
Takeoff airport has ILS Approach :
CAT I - DA(H) 250 (200) / RVR 550
CAT II - RA 100 / RVR 300
CAT III - RA 50 / RVR 175
Looks like I could come back and land at my departure airport with CAT II or III, but CAT I is questionable due to 200 feet ceiling.
Do I need a Takeoff Alternate?
