NTSB Safety Recommendations A-11-12 through -15

************************************************************

The National Transportation Safety Board makes the following

recommendations to the Federal Aviation Administration:

Perform a technical review of Airport Surface Detection

Equipment-Model X to determine if the capability exists

systemwide to detect improper operations such as landings on

taxiways. (A-11-12)

At those installation sites where the technical review

recommended in Safety Recommendation A-11-12 determines it

is feasible, implement modifications to Airport Surface

Detection Equipment-Model X to detect improper operations,

such as landings on taxiways, and provide alerts to air

traffic controllers that these potential collision risks

exist. (A-11-13)

Amend Federal Aviation Administration (FAA) Order 7210.3,

"Facility Operation and Administration," to direct that, at

airports with air traffic control towers equipped with

airport lighting control panels that do not provide direct

indication of airport lighting intensities, the air traffic

manager annually reviews and compares, with the airport

operator, the preset selection settings configured in the

tower lighting control system to verify that they comply

with FAA requirements. (A-11-14)

Revise Advisory Circular 150/5345-56A, "Specification for L-

890 Airport Lighting Control and Monitoring System (ALCMS)"

to state that airport operators should inform air traffic

managers of variances for, or modifications to, airfield

lighting preset standards prescribed in Federal Aviation

Administration requirements. (A-11-15)
