## GDP-E Prototype Operations Update 

**Software frozen since November 17.**
**Since last meeting (2 months) we have fixed 9 STRs.**
**Filtering was finally turned on.**
**Performance, reliability continue to be excellent.**
**NavCanada is now running CDM GDP’s at Toronto Center.**
**FSM now at Vancouver, Edmonton, and Montreal centers.**
**Participant changes:**
**New: CDN, CDR, ONT, UPS**
**DAL new feed operational**

## Slide 4

## GDP-E Build 1 Full-scale Development (FSD) Update

**FSD items are still in testing:**
**Master-slave (done)**
**Flight data feed re-architecture (waiting for airlines)**
**Diversion processing (in progress)**
**ID change processing (in progress)**
**CDM data into regular ETMS reports (in progress)**
**Bug fixes (in progress)**
**Targeting deployment to prototype operations in January.**

## Flight Data Feed Issues

**For carriers feeding over CDMNET only!**
**New software provides redundant data servers.**
**Airlines must configure new IP addresses.**
**Airlines should to establish procedures or modify software to switch servers in case of failure.**

## Diversion Recovery Issues

**Data Issues:**
**Diversion processing full of strange data.**
**Neither diversion remarks or automated diversion detection will be fool-proof.**
**Need help verifying correctness of both.**
**Substitution Issues:**
**A diversion recovery will pick up the substitution status of the diverted flight, which may create subtle problems; examples:**
**if diverted flight was SI-cancelled, you will not be able to SI-cancel the diversion recovery until a new EDCT is issued.**
**If have an outstanding “sub chain” and an open slot is attached to the diverted flight, it will now be attached to the recovery.**
**If you want to test this before it gets deployed, let me know.**

## GDP-E Build 1 Enhancements

**Development complete 12/17/99. **
**Includes:**
**Remaining steps of compression cycle improvements**
**Departure data in ADL**
**New ADL format**
**Ground stop tool support**
**Will begin inter-operability testing with Metron 12/20/99.**
**Targeted for deployment when 1.8 released.**

## ADL Changes

**Departure data:**
**Airport Departure Rate (ADR)**
**GDP-related:**
**FADT times (list of all EDCTs issued in GDP)**
**Control type (GDP, FA, COMP, BLKT, GS, UPD, SUB)**
**Exempt flag (show if flight exempt in last GDP)**
**Slot Hold flag (for use with simplified subs)**
**Major Carrier (who subs for this flight)**
**Ground Stop Related:**
**Ground Stop Parameters**
**NOTE: GS delay flag will start to be used**
**Miscellaneous:**
**Diversion recovery flag**
**OOOI fields (to be filled later)**
**Deleted: Maturity Flag, Slot Class**

## Build 2 Enhancements

**Simplified subs has top priority; testing targeted for March 3.**
**Other high-priority items for near-term development:**
**Departure Fixes (move up?)**
**Daily Download (July)**
**OOOI Data (move back?)**
**Schedule dependent on final budget, CR priorities.**
