Question

Refer to the KPBI ILS 10L approach chart. The DA for an S-ILS 10L is shown as 216 feet, but what visibility is required for landing with a functional autopilot?

1) 2400 RVR, but only if you let the autopilot land the aircraft.
2) A visibility of 1800 RVR is authorized for the S-ILS 10L if the pilot is using a flight director, an autopilot or a heads-up display (HUD) in the cockpit.
3) One-half statute mile.
4) 2400 RVR only.

Answer 1

The required visibility for landing on the S-ILS 10L approach at KPBI with a functional autopilot is 1800 RVR, as this is the authorized visibility when using a flight director, an autopilot, or a HUD.

Step-by-step explanation:

The student's question pertains to the specific visibility requirements for landing on the Standard Instrument Landing System (S-ILS) 10L approach at KPBI, given certain avionics are used. The chart indicates a decision altitude (DA) for the S-ILS 10L approach as 216 feet. The visibility requirement for landing with a functional autopilot, according to the approach chart, would be 1800 RVR (Runway Visual Range). This visibility is authorized when a pilot is utilizing advanced cockpit tools, such as a flight director, an autopilot, or a heads-up display (HUD).

The visibility required for landing with a functional autopilot on the KPBI ILS 10L approach is 1800 RVR. This is authorized if the pilot is using a flight director, an autopilot, or a heads-up display (HUD) in the cockpit. This means that if the pilot is using any of these instruments, they can proceed with landing when the visibility is at least 1800 Runway Visual Range.
