Today was the fist day back in a DCA cockpit. It didn't turn out how I had planned it. I had planned a nice little solo IFR cross country flight up to Atlanta, got to the airport and was told my flight was cancelled. Due to the fact that the were planning the hurrevac, All long distance x-countries were cancelled. /ubbthreads/images/graemlins/mad.gif I was able to go local, so I decided to go practice some approaches. Called to file my IFR flight plan and did the weight and balance. I got the can and headed out to the aircraft. When I get ready to start the a/c I notice that I didn't have the key. So I haul butt to ops to find the key. When I get back with the key an instructor and the fuel guy who is also an instructor give me the warning never to leave the aircraft untied while unattended. /ubbthreads/images/graemlins/crazy.gif I appoligize and aggree and hop in and strart it up. As I taxied out I guess I did not see the fuel truck off my wing /ubbthreads/images/graemlins/banghead.gif, and would definitely hear about it when I got back. Did the DME ARC/VOR into Kissimme. On the missed I filed for the VOR into ORL, but I asked if MCO could fit me in for two approaches, which was granted. I got to do an ILS into 35L and an ILS 36R. On the ILS for 36R I was cleared for the option so I requested a full stop and taxi back. There's a lot of runway to use, made a nasty crosswind landing due to a nice gust. I got clearance to taxi back via B and B10 for a 36R departure. On the inner taxiway I taxied along with a Delta 777. A big size diffential! Took off and got vectors for the ILS for 9L back into Sanford. Landing was uneventful. Upon my return my instructor was waiting for me. He asked what the distance you can taxi by a fuel truck and when you're suppossed to tie down the aicraft. I definitely didn't have my head in the game as far as airport ops are concerned, which is a big safety issue that could have been avoided had I slowed down and not been in a hurry to get up in the air.
