## CDM DRVSM WG 

- Amanda Stott, WG Lead FAA
- Bill Cranor, Industry Lead
- US Airways

## DRVSM WG Tasks

- Task 1: Develop and implement traffic flow management strategies/plan in support of DRVSM implementation Jan 05
- Task 2: Develop and implement strategies/plan to mitigate the compression of aircraft that may plan into particular sector or airspace (addition of 6 additional flight altitudes)
- Task 3: Identify and implement strategies/plan to monitor/manage impact of non-RVSM approved aircraft operating in the system at one time.
- Task 4: Develop and implement strategies/plan to de-conflict primary & secondary traffic flows to increase efficiency and maximize en-route flexibility.

## Slide 3

## DRVSM TFM PLAN

- Pre-implementation: (1 year to 24 hours before start
- DRVSM Implementation: 24 hours through 72-96 hours after (still draft)
- Post-implementation Follow-up: (TBD) estimated to be at least 90 days. Possible that group will continue until HOST updates for Aircraft Equip. Suffix resolved

## CDM Coordination

- Updates and Coordination:
- CDM Meetings, S2K, others
- FAA TMO Update Telcon at each meeting posted with the agenda on web
- Customer Update telcon
- Post on CDM website
- Coordinate with CDM Training, RVSM Program Office, HAR/NAR, ATCSCC Procedures, FEA WG, others as needed.

## Exception Procedure

- Highlights:
- Requires coordination before acceptance into airspace based on 3 categories (DOD procedure still being worked)
- Automated solution being pursued via NTML
- (more later)
- ETMS Requirements being worked (more later)
- 72 Hour (proposed) restriction on access to RVSM by non-Approved Aircraft.

## Exception Procedure - NTML

## Cost/Benefits for DRVSM

**Industry will invest a minimum of $600 million (ATP-6)**
- Example of how that investment looks from one Major Airline
- 	$1.6 million per fleet type (older generations)
- 	$8-10K per aircraft (average)
- 	$7K additional recurring maintenance cost per aircraft 		(estimated)
-  Program Office has estimated a $350+ million annual savings 	based on reduced fuel consumption
- *Additional Savings are possible and must accompany an effective implementation to recoup the investment from industry and make future risk investment possible.

## Suggested DRVSM Benefits - Customer

- Increased availability of optimum altitudes (1-5000ft)
- Reductions in re-routes due to reduced sector complexity
- Review, analysis and reduction elimination of certain MIT 	restrictions
- Improved flexibility and system throughput during “Severe Weather”
- Support increased route flexibility for NRP (HAR)
- Improve ability to airborne hold at altitude

## DRVSM Benefits Metrics - Customer

- TFM Based: (Draft)
- 	Delays >15 <15
- 	Block Time (more discussion) trends
- 	Delays/Cancellations
- 	Fuel Burn
- 	Flown as Filed
- 	MIT reductions elimination
- 	OTHERS?

## DRVSM Benefits Metrics - FAA

- TFM Based:(rough draft)
- Altitude Occupancy:
- MIT
- TMI’s (GS, NRA, other)
- Reroutes
- CDR’s
- LOA’s (crossing altitudes)

## Analysis Tools

- POET
- PDARS
- SDAT
- Others, (additional resources for analysis)

## Key Risks

- Automation Issues (Aircraft Equipment Suffix /W /Q)
- Integration into other NAR activities
- HAR expansion
- Integration with Regional Airspace Designs (SEAWG)
- European Experience of (Hero-Villain)
- Mexico/Canada/Caribbean
- Resources:
- People, funding Industry Equipage and Time
- Safety Assessment Completion (July 2004)
- Stakeholder timely buy-in for procedures and key decisions
