Which minimum is used for Jet ICLS with SPN-46 monitor landings?

The minimum for Jet ICLS (Instrument Carrier Landing System) with SPN-46 monitor landings is 200 feet above ground level and ½ mile visibility. This decision is based on operational safety standards and procedures that have been established for carrier-based operations, ensuring that pilots have adequate vertical and horizontal references during their approach phase.

In the context of landing operations, the choice of 200 feet for the minimum decision altitude offers a sufficient safety buffer for pilots to visualize the approach and landing environment while still allowing for a relatively low minimum altitude that reflects the operational characteristics of jet aircraft. The visibility of ½ mile is consistent with the requirements necessary to safely engage the landing system.

Other choices, proposing different minimums, do not align with the operational requirements or safety standards for Jet ICLS landings as defined in the relevant aviation regulations and guidelines.
