Piper18O
Pre-takeoff checklist
I have been debating to post this, but I guess it could serve as a learning tool for others. One change however is that the tools we all have are much different today than what was available to me back in the mid 1990's. My best friend and I had spent a week in Oshkosh at Airventure, and were preparing to depart on the last morning. I wanted to depart IFR, because with everyone trying to get out of there, I knew that IFR departures got priority. 'We were all packed and ready to go. I headed to the pay phone to get my briefing, and to file the flight plan. (yes, this was before widespread use of cell phones) The only weather of real concern on the entire route of flight from OSH to Kansas was some level 1's and 2's showers that were falling apart and dissipating, (as the controller said "probably not even hitting the ground any more" near Madison. After that, it was severe clear the rest of the way home. I filed the plan, we jumped in the plane, and started to taxi. Even with priority, it was still probably 25 minutes before we finally got to take off. We departed runway 27 and climbed to 6000 ft in the old Piper Cherokee. We were IMC at about 3500 agl, and it was pretty benign. I had no autopilot, but since I had never used one, I didn't know any different. I knew that my time in the soup was only going to be about 20 or 30 minutes, so I figured I would have no issues maintaining my scan for that amount of time. Everything was going fine until we got pretty close to Madison. It started getting kind of bumpy, (still IMC) and then shortly thereafter, all hell broke loose. We were getting thrown around like a rag doll, gaining and then losing 300-400 ft in a matter of seconds. Even though we were seat-belted in, we both hit our heads on the ceiling 2 or 3 times. Lightening flashed all around us intensely, and it was so close, at one point I was sure we had been struck. Our time in that cell was only about 3 or 4 minutes, but it seemed like an eternity. We emerged on the other side no worse for wear, but both of us had some serious cleaning to do of our pants, so to speak. I requested a frequency change to converse with flight watch, and it was granted. After giving our pilot report and asking what it was that we flew through, we were asked if we were aware of convective sigmet number xxx. I said no, we hadn't received that during the briefing or with tower or departure. Apparently the level 1 and 2 showers had unexpectedly intensified into level 4 and 5's. My question is why were we never notified? Was it because the frequencies were so jam packed busy that they never had time to notify us, or was it maybe because it had been issued while we were still on ground control and it was never forwarded to us. I know departure was very busy, but shouldn't they have told me about my impending doom prior to entering the cells? Just curious what others may think about the whole situation.
