Wednesday March 3, 2010

Overview• Introduction

– AeroNav Services– What We Do

• Getting an Instrument Flight Procedure – Preliminary Actions/Requirements/Request– Timeline

• LPV Approach

• RNP Approach

• Approach Cancellation Program




AeroNav Services




National Flight Procedures Office (NFPO) in OKC and 3 Regional Flight Procedures Offices (FPO) (ATL, SEA, and DFW)

• Design and develop instrument flight procedures

Flight Inspection Operations Office in OKC and 6 field offices (ATL, ACY, BTL, OKC, SAC & ANC)

• Operate and maintain a fleet of flight inspection aircraft for airborne evaluation

National Aeronautical Charting Office (NACO)• Publish aeronautical charts and digital products for aviation

around the world




How to request an IAP

• Requests can be received from anyone. Requests from ATC should be coordinated through the OSG.

• The request can be made via the internet at “avn.faa.gov” or through written request to our office.




Considerations for Getting an Instrument Flight Procedure

• Costs/Benefits/Traffic Count/Safety• Airport Design/Aircraft Types• Approach Types/Minimums• Surrounding Terrain/Obstacles• Construction plans• Facility availability/restrictions

Points of Contact




Instrument Flight Procedure Problem Areas

• Data Issues– Conflicting Runway Data based on new surveys/NFDD– Untimely Updates (facility ID, airport ID/name)

• Timely Obstacle Data– Survey complete and load data, tree removal– Do you have the proper survey -- VG or NVG

• Late notification of project commissioning dates• Last minute design requests




Regional Airspace and Procedures Team (RAPT) Responsibilities for Flight Procedures

• FAA’s single point of contact for requests of flight procedures

• Processing Requests (WEB site)

• Coordinating• Prioritizing• Evaluating• Responding• Tracking




RAPT Priorities• Priority 1 - Safety, anything to correct a known safety deficiency• Priority 2 - Newly installed or relocated NAVAIDs or airport runway

addition/change• Priority 3 - Procedures which test or implement an FAA initiative• Priority 4 - Procedures at airports with no existing IFR approach• Priority 5 - Procedures providing a reduction in minima• Priority 6 - Procedures which eliminate the requirement for a waiver

or NOTAM• Priority 7 - Procedures providing flow improvement• Priority 8 - Procedures providing other benefits, new criteria

compliance• Priority 9 - Public use procedures not included in 1 through 8• Priority 10 - Special and private procedures not providing benefits of

1 thru 8




Timeline for Instrument Procedures

• Establish Pub Date: – Production Cycle (174 days). Full capacity thru 05/31/2012 (2,600 pending tasks between now and then)

• Example Flow based on Sept 23, 2010 pub date:– Feb 2010: FPO should have all data for their review– 4/2/10: FPO must fwd project to NFPO– 5/17/10: NFPO must fwd project to QC (45 days)– 6/16/10: QC fwd to FC for scheduling (30 days)– 7/24/10: SAT FC must be posted. (38 days)– 7/27/10: NFPO must fwd pkg NACO/NFDC (3 Days)– 9/23/10: Procedure published (56 day TPP cycle)




•An LPV is a satellite based Approach procedure with vertical guidance.

•An LPV can provide minimums as low as CAT I ILS

(w/ approach lights and appropriate infrastructure). •An LPV Approach requires a “VG” survey.

•An LPV must have a clear GQS.

•Missed approach needs to go straight ahead initially

(until 8260.54 implemented)

What is an LPV?




What is an RNP?

• An RNP is a satellite based Approach procedure with vertical guidance that includes onboard performance monitoring and alerting capability.

• Required Navigation Performance has different widths available (RNP 1.0, RNP 0.3, RNP 0.2, RNP 0.11)

• Radius-to-fix turns (RF) commonly used to reduce flight distances and avoid airspace/obstacles. (Not all RNP equipped aircraft have RF capability)

• Most airlines now equipped and all Commercial and Gulfstreams coming from factory with RNP. Training and certification are still required.




Instrument Approach Procedure (IAP) Cancellation Program

• Cancellation Program was developed to identify those procedures which can be eliminated with little or no impact.

• The goal has been a 2 to 1 ratio, 1 cancellation for every two procedures added to the NAS

• Over 1,000 Procedure have been Cancelled in the last three years

NDB IAPs

VOR/DME RNAV procedures

VOR – Seldom used approaches




Benefits of Cancellation Program

• Transition to Satellite based navigation; RNP, VNAV, LPV procedures provides lower minimums than the procedures they typically replace

(ie: NDB; VOR)• Less Cost to Technical Operations • Reduced Airspace Complexity• Reduced Flight Inspection Operational
