Airport Deicing Question

[[email protected]]

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?

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"

This is due to the aircraft "holdover" times each aircraft is issued
based upon departure time and the time after deicing is completed,
based upon number 1 or 2 deicing method.

Have a great one!

If de-icing is required, then the weather is usually bad. Bad weather brings
inherent delays on it's own. Add the time required for de-icing (20 minutes
to an hour or more) to the time spent sitting in line waiting for a
departure slot due to traffic saturation because of increased aircraft
seperation. Sometimes, if you are held too long for a departure slot, you
have to de-ice again. Sometimes you burn so much fuel while waiting that you
have to return to the gate for more fuel and then you have to de-ice again
because of the increased time of delay.

D. It's a snowball effect. :-)
