Our long-time OpSpecs instructor, the legendary Pat Malone, enjoyed showing us "loopholes" and "gotchas" in the minimums. For example, the RVRs might be too low for Rwy 9, but legal if you use 27; or if the prevailing visibility is OK, taxi to a runway that doesn't
have an RVR.
She'd always warn: "This is merely what's legal, not necessarily what's safe."
