Final answer:
The alternate weather minima requirement for facilities with multiple usable precision approaches is either 600‑2* or 300-1 above the lowest usable HAT and visibility, whichever is greater.
Step-by-step explanation:
For facilities with TWO OR MORE USABLE PRECISION APPROACHES, each providing straight-in minima to separate suitable runways, the Alternate weather minima requirements is:
a) 600‑2* or 300-1 above the lowest usable HAT and visibility, whichever is greater.
b) PRECISION APPROACHES, each providing straight-in minima to separate suitable runways 400‑1 or 200-1/2 above lowest usable HAT and visibility, whichever is greater.
c) 800‑2* or 300-1 above the lowest usable HAT/HAA and visibility, whichever is greater.
