| AREA
| MAIN IMPACT
|
| 1. Delay the programme to move LTCC to Swanwick by one year and defer associated investment until CP2
|
- Operating cost reductions of c£17m pa from closure of West Drayton delayed by 12 months
- Significant increase in risk of failure to complete the Centre consolidation programme to plan, with delays to reductions in support costs
- Removes window in CP2 to implement NERC1 system developments (eg iFACTS implementation) and achieve the capacity increases
- Increase risk that LTCC capacity will be constraining before it is transferred to Swanwick
|
| 2. Limit investment on NERC system software on system software in remaining yesars of CP1 to address safety or business critical priorities only
|
- No further capacity increases from sectorisations or systemation during CP1 with delay implications later this year
- Insufficient development of NERC1 system to support EPS and iFACTS increasing the risk that NATS will not be able to provide capacity increases during the CP
|
| 3. Cease development investment in EPS and iFACTS - do not implement on NERC1 system
|
- EPS-enable ATSA reductions not achieved
- Potential for obtaining capacity increases from iFACTS is lost
|
| 4. No investments to sustain or develop simulator and workstation equipment at Air Traffic Training and Simulation Centre (ATTSC). (Cutting investment in sectorisation removes the need for development activity at ATTSC)
|
- NATS capability to grow capacity through re-sectorisation will be lost. The regeneration of this capability will be costly and challenging
- NATS will be reliant on Eurocontrol for development work and industry-developed products
|
| 5. Replace Oceanic system hardware only and defer investment associated with system replacement until CP2
|
- Service benefits to Oceanic users of improved profiles will not be provided
- Delay to introduction of reduced horizontal separation in Oceanic airspace, with potential downstream capacity limitations
|
| 6. Limit investment in business systems to essential replacement only
|
- Operating costs savings not realised
|
| 7. Defer accommodation moves |
- Operating costs savings not realised
|
| 8. Reduce Minor projects expenditure by 30%
|
- Increases risk of ability to deliver programme within planned cost
|
| 9. Remove all remaining contingency in CP1 |
- Increases risk of ability to deliver programme within planned cost
|
| 10. Unspecified efficiencies of 10% on the remainder
|
- Increases risk of ability to deliver programme to specification
