JYO is 3,500 feet long but from the air it looks longer. So when you take off and are about 1/2 way down the runway you wonder why you are not airborne. It is now in the ADIZ and what a nightmare. I came in just before the snowstorm of January 23, 2004. The people are super courteous so you know in advance that it is going to be expensive. Fuel is $3.50 a gallon with taxes and this gives you overnight parking. They have no preheater or deicing. Who would want that liability? They will put you in the hangar overnight or for 2 hours at the same cost, a real barging if you ask me. $75.00 for a PA30 and it was ready to go. There had been 2 feet of snow and ice on the wings. It cranked right up. Taxing out I called 118.55 and learned that you have to have a flight plan on file and it must be filed over the phone or in person at the local flight service station. So I had to shut down, walk over to flight service and file. You can file direct to Winchester, VA, which gets you out of the ADIZ. So I taxied out the second time and 118.55 came right up with a squawk and in-flight frequency so quick that I copied 120.05 for 125.05. I even read back 120.05 and was told this was right. So off I went and when I finally got Dulles approach the radio burned my ears. "We have been trying to get you for the past 20 miles and if you are a PA30 why is your ground speed only 80 knots?" It was like that all the way home. My heading was 244degrees and my ground speed would go to 65 knots at times. What a wind while the surface wind was 3 mph. I fly aerobatics but it was so rough below 6,000 feet that I flew at 8,500. I would hit down drafts that brought my airspeed to 95 knots with a ground speed of 50 knots and I was still descending at 100 fpm. Once I passed Lewisburg, WV the ground speed climbed to 120 knots. I was thankful for this although I am used to seeing 155 knots at cruise.
