With respect to surface traffic awareness, an RTCA industry committee has begun development of standards for the use of Automatic Dependent Surveillance-Broadcast information to improve situation awareness and alert for potential runway incursions. We recently asked this committee to accelerate its efforts, and to investigate simple improvements that industry could implement within the next few years and may be eligible for use in a portable EFB (Class II).

. 
In addition to this standards development, we supported the certification of the Honeywell Runway Awareness and Advisory System.

FAA Data Communication Program Segment 1: working with industry, we plan to publish supporting guidance material for taxi clearance in 2009. The implementation of data link taxi clearance will depend on the data link program, which the FAA Joint Resources Council is reviewing.

ATO Efforts

. 
Mandatory detailed taxi instructions, including directional turns (directional turns are optional on needs at individual airports), to all aircraft and vehicles to and from ramps and runways.

. 
Prohibit the issuance of a takeoff clearance during an aircraft’s taxi to its departure runway until after the aircraft has crossed all intersecting runways. If the aircraft is not able to completely cross a runway prior to reaching its departure runway then air traffic control will issue a runway crossing clearance with the takeoff clearance.

. 
The ATO will eliminate implied crossings, such as “taxi to” to require explicit runway crossing clearances. This recommendation calls for an explicit crossing instruction for each runway after the previous runway has been crossed and will require a change to Code of Federal Regulations section 91.129(i) and FAA Order 7110.65.

. 
Runway-to-runway crossing clearances. This recommendation to amend FAA Order 7110.65 to require air traffic controllers to issue an explicit crossing instruction for each runway after the previous runway has been crossed.

. 
The FAA is considering adopting ICAO procedures for landing clearances. This change would require controllers to wait to issue a landing clearance to a following aircraft until the preceding aircraft has crossed the runway threshold. Other options under consideration would specify when a controller can issue a landing clearance to an aircraft by restricting the distance from the runway before issuing the landing clearance. 

. 
The FAA is considering the standardization of terminology by adopting the ICAO phraseology “line-up and wait.” This would change the existing FAA Order 7110.65 phraseology of “position and hold.”

FAA Office of Airports (ARP) Efforts

. 
Work with ATO and Jeppesen to explore a better system for updating the airport diagrams for construction issues.
