Overview • Ground spacing tool that was baselined & funded as part of the

2007 SBS JRC decision • Ground Interval Management – Spacing (GIM-S) comprises a set of

ground functions to: – Improve metering by reducing long freeze horizons to shorter distances – Minimize the use of vectoring for problem resolutions – Increase fuel efficiency by absorbing delay at higher altitudes than in the TRACON – Provide speed advisories to assist in the delivery of aircraft to a Meter Point/Meter Fix – Improve ETA/STA performance as the NAS equips with ADS-B avionics

• Functionality allocated across multiple platforms, creating this NextGen capability

• ZAB selected as the GIM-S Key Site, for the arrival metering into PHX on the EAGUL5/6 – EAGUL5 will become the EAGUL6 on Sept 18, 2014 – GIM-S IOC on Sept 22, 2014

Speed Advisory Details • Mach speed instructions will be issued at-or-above FL240

– It is understood that currently, pilots expect Mach/IAS transition to occur ~FL290-FL300,

– Improves the GIM-S performance and accuracy – At FL280, difference in M0.01 = 4 knots vs. FAA required IAS

increments of 10 knots – Speeds issued in Mach may be as low as M0.68 – Winter months in ZAB – adverse rides in mid 30s flight levels result in

greater number of aircraft in mid 20s flight levels

Speed Advisory Details • Speed instructions provided only when aircraft are in

level flight • GIM-S speed instructions will not be issued after SLIDR

on EAGUL5

Summary • ZAB will begin metering 500NM from PHX on

EAGUL 5/6 vs. traditional metering of 160NM on the EAGUL5

• Delays to be absorbed in ZAB are now segregated between sectors and flows further upstream than today,

• Speed instructions can be provided to absorb these delays
