Arrival Rate may be decreased.. as there are no open parking places for
arriving aircraft while waiting for those already there to depart.
Departure Rate is decreased because you cannot deice and launch as quickly
(aircraft per hour) as you can on a "dry day"

The FAA website provides information about airports that are currently
deicing aircraft via their website at...

http://www.fly.faa.gov/ois/

When an airport is reported as deicing the acceptance rate and
departure rate is also provided. Why is this? How does deicing affect
AR and DR? If an airport is deicing is is more likely that arrivals and
departures will be delayed?
