What is the normal approach minima for a CAT I ILS?

Explanation:
The key idea is the standard minima that define a CAT I ILS approach: a decision height and a minimum runway visual range. For CAT I, you must be able to see the runway environment and continue to land at a DH of 200 ft above the runway and with an RVR of at least 2600 ft (about 800 meters). The DH of 200 ft gives a safe, lower limit for making the landing decision, while the 2600 ft RVR ensures there’s enough visibility along the runway to navigate and align with the approach lights and runway. Values much lower, like a DH of 100 ft or an RVR around 1200 ft, would push toward CAT II/III minima or unsafe conditions for CAT I, so they aren’t the normal CAT I combination.
