I read that the opposite direction had a NOTAM exclusion, i.e. was excluded from use. From the professional pilot forum linked a few days ago in a similar thread.
If that's right then OP would be correct in saying, this direction wasn't meant to be used.
Depends on why it was NOTAM’d - could be that the localizer was out, that there was a noise abatement, or other reasons.
Part of preflight is investigating those so you know what are options at what are not - entirely closed runways will be indicated if they’re actually broken up or just marked closed.
Ok but in an emergency all bets are off, the opposite direction is better than a crash landing. So you can't just assume 100% of landings are in one direction.
