The United States

There is free parking here by the control tower. Alternatively, you can park on the other side of the field at North Atlantic for $5/day (piston single).

North Atlantic makes three trips a day with their truck to fuel planes in this area, so you can still get fuel without taxiing across, as long as you plane is there long enough.

For a piston single, quoted over the phone 2008-05-16:

Landing fee: none

Handling fee: $10 (waived with fuel purchase)

Parking: $5/night

Note that there is also free parking under the control tower on the east side of the field, if you prefer.

I think this is the only FBO at Capital City Airport. They've blocked comments on AirNav, but here's what I got from a phone call today for a light piston aircraft:

Facility fee: $25.00 (waived with 5 gallon fuel purchase).

Ramp fee: $15.00

Landing fee: $8.00 (she wasn't sure about the exact amount)

It doesn't make sense for a quick fuel or lunch stop. Nearby Harrisburg International (KMDT) also has the landing fee, but not the ramp fee at the FBO.

The airport has an $8 landing fee for light piston aircraft, but the FBO has reasonably good gas prices ($5.20/gallon on 12 May 2008).

I came to Dulles for the first time as pilot yesterday. The ADIZ was a total non-issue when I was IFR (just like any IFR flight). Potomoc approach and Dulles tower were friendly and co-operative, fitting me into the jet traffic in bad weather without any delays and giving me the runway I asked for. It was about a 3-minute taxi to Signature. They had a follow-me van waiting on their apron, and then a shuttle to take me about 50 meters to the FBO (in the rain). I waited 8 minutes for a Washington Flyer taxi to arrive from the terminal. All prices as quoted in a previous message -- cheap for a big airport (except for the fuel, of course).
