AVIATION & AERONAUTIC CALCULATOR
Cat I Minima
A precise tool.
What is the Cat I Minima & How does it work?
Category I Instrument Landing System (ILS) minima are established to ensure safe landings under specific visibility and altitude conditions. These standards are crucial for maintaining aviation safety, especially in low-visibility environments.
DH = 200 text{ ft}
DH = Decision Height
The Required Visual Range (RVR) for Category I ILS is set at 550 meters. This means that the pilot must be able to see the runway environment clearly within this distance to safely land the aircraft.

Frequently Asked Questions
What is the Decision Height (DH) for Category I ILS?
The Decision Height (DH) for Category I ILS is 200 feet.
What is the Required Visual Range (RVR) for Category I ILS?
The Required Visual Range (RVR) for Category I ILS is 550 meters.
Why are Category I ILS minima important?
Category I ILS minima ensure safe landings under specific visibility and altitude conditions, crucial for aviation safety in low-visibility environments.
Can pilots land with lower RVR than 550 meters?
No, pilots must be able to see the runway environment clearly within 550 meters to safely land under Category I ILS minima.
What happens if a pilot cannot meet the DH and RVR requirements?
If a pilot cannot meet the Decision Height of 200 feet or Required Visual Range of 550 meters, they must execute a go-around procedure to ensure safety.
