Regarding feedback: I'm all for increased frequency. As you know, Airline Operations is what I do for a a living, and this is the only place I get data-heavy info like this
I think you may need to broaden your aperature on delay and methods of traffic management? Delay in-and-of itself is not necessarily the root of inefficiency.
There are many sub-metrics to GDP use that, (while not in the public domain), are useful in determining the planning and execution aspects of a GDP.
A short list includes:
- Was the GDP implimented within 2 hours of "start-time"
- Did a Ground Stop precede the GDP
- Did the FAA use a variable AAR, or was the assumption that all hours have equal capacity
- Was the GDP rate modified after implimentation
- Was the GDP cancelled early
Delay should be used as a tool to an acceptable outcome when capacity is constrained. GDPs can be effective when used properly. However, they have to be viewed in the context of other impacts such as completion rate, airborne holding, ground stops, diversions, etc, etc.

Just my opinion.....
Is there an APP for Aerology??
