FLIPINT – Flight Plan Intent
ITP – In-Trail Procedures
M&S – Merging and Spacing
C&P – Crossing and Passing
PAIRAPP – Paired Approaches
D-OTIS – Data Link Operational Terminal Information Service
D-HIWAS – Data Link Hazardous Weather Service
RVR – Data Link Runway Visual Range Service
D-FLUP – Data Link Flight Update
Information sent to aircraft on known flight delays/constraints, using the Data Link Flight Update Service. 11

12. Avionics
Leveraging significant existing equipage base (e.g., FANS 1/A+ over VDL-2)
Supports early services and benefits (e.g., DCL) TOWER
Working with avionics manufacturers and service providers to determine how far these avionics can carry us into Segment 2 services
Working with avionics manufacturers to develop SC-214/WG-78 avionics fully NextGen capable avionics
Draft standard complete in Dec 2009
Standards validation work planned for 2010/11
