  1. Transition to Advanced Navigation Systems Hershey Airport Conference Gerard Lebar – Eastern Flight Procedures Wednesday March 7, 2007

  2. The Expanding National Airspace System • 4,000 Public Use Airports (Paved) • 14,800 Instrument Approach Procedure • 10% annual growth • 30,000 Obstruction Evaluations • 18% annual growth

  3. NDB (No FAF) IAP TRAP 1. Length: Starts at Facility & extends out 10 NM. 2. Primary Area: 2.5 NM wide at Facility & expands out uniformly to 8 NM at 10 NM point. 3. Secondary Area: 0 NM at Facility & expands out uniformly to 2 NM at 10 NM point. 4. ROC: 350 FT.

  4. RNAV (GPS) IAP TRAP 1. Length: Starts at Thld & extends out 5 NM. 2. Primary Area: 1.0 NM each side of FAWP & tapers in uniformly to .5 NM at the MAWP Displacement area. 3. Secondary Area: 1 NM wide at the FAWP & tapers to a width of .5 NM at the MAWP Displacement area. 4. ROC: 250 FT, Primary Area 250 Ft at inner edge & 0 Ft at outer edge.

  5. CAT I/LPV TRAP Starts at Threshold and extends about 5 NM (depends on GS Intercept Altitude Threshold width 400’ each side of Rwy Centerline for W surface. At Precsion Final Approach Fix, width is 2200’ each side of Rwy Centerline for W surface There are two secondary surfaces (X and Y) that have 4:1 and 7:1 slopes (See slide seven for graphic) ROC is clear 34:1 slope with no GQS penetrations.

  6. New Required Navigation Performance (RNP) Procedures

  7. Final segment size LPV FINAL RNP FINAL

  8. New Required Navigation Performance (RNP) Procedures

  9. IAP Cancellation Program NDB IAPs – Cancelled nearly all NDB approaches. Only kept those where there were no other ground based approaches (VOR or ILS/LOC) VOR/DME (RNAV) – Converted to RNAV (GPS) approaches VOR - Seldom used approaches – only after coordination with Air Traffic and Airport Managers
