## Question of Supply vs. Demand

**ASE:  8 per hour if IFR, 12-16 if VFR**
**EGE:  6 per hour if IFR, 10 if VFR**
**RIL:   4 per hour if IFR, 8-10 if VFR**
**On Peak days, the E-STMP website may receive as many as 5000 hits within the first 30 seconds of availability**
**There are often 0800-1000 people trying for 4 to 16 available slots in a given hour on peak demand days**

## Ski STMP History

**Established for decades**
**Began as an effort to smooth the peak demands experienced mainly at Aspen, and Eagle CO.**
**Was first operated manually with reservations made person-to-person over the phone.**
**Next step was the integration was a DOS-based PC application with six incoming phone lines.  It was operated off of two PC’s located at ZDV ARTCC.**

## Ski STMP-Today

**The current Ski Country STMP is web-based and operates from servers located at the ATCSCC.**
**Slot accessibility is still available through the Automated Voice Airport Reservation System.**
**ATCSCC ARO at 703-904-4452.**

## CDM STMP-E Workgroup

**FAA-Industry joint team formed in 2003 to improve the STMP process.**
**Workgroup meets several times each year to recommend enhancements to the STMP.**
**Workgroup comprised of individuals from the FAA, flight plan service providers, fractional jet operators, traditional Part 91 flight departments, and AOPA.  **

## Workgroup Enhancements

**Recommended User Profile information be updated yearly to provide better data to the system.**
**Simplified reservation format to make it easier to recognize what airport the slot if for (now includes ASE, etc in the reservation number).**
**Reduced the time frame requiring reservations to just 3 periods over the course of the season instead of running Nov-Apr. **
**Recommended new servers with larger bandwidth be installed at the ATCSCC to improve the E-STMP website.  **

## Workgroup Enhancements cont.

**Changes to the Recommended E-STMP website such as redesigning the slot availability screen to make it easier for users to view cumulative number of slots available at an airport.   **
**Created a reservation confirmation process to aid in improving the statistics on unused slots.**
**Assist in the data auditing process done by ZDV, ARO, and GA Desk to ensure compliance and validity to the data.**

## Recent Recommendations

**CAPTCHA (Completely Automated Public Test to tell Computers and Humans Apart)**
**A website security solution designed with GIMBY CAPTCHA image is proposed by the FAA to prevent automated STMP reservations. **

## Additional Recommendations

**Annual STMP Profile Purge/Update each November.**
**March 2007 ATCSCC perform data  analysis on success of CAPTCHA implementation.**
**Web site access for Users to obtain Reservation reports. **

## Registration Form

- Current

- NEW

## Update Profile Form

- Current

- NEW

- _Note_: This page is shown to users who have registered before 12/08/2005.

## Additional Process Changes

**Confirmation process changed from 8 hours prior to reservation time to 12 hours prior.**
**Confirmation needs to be completed between 24 and 12 hours prior to your reservation time.**

## Continuing Issues

**Too much demand, too little capacity**
**Secured reservations still go unused (33.5% for ASE/EGE/RIL 2005-06)**
**Too many misconceptions by the users (“fractional operators taking all slots”)**
**False entries can still be made (not tied to aircraft registry database by user)**
**No real enforcement exists for abuse**
