I didn't write up lesson #4, but it went well. It's nice to get back to more stable, summertime weather conditions. It makes it easier to practice turn coordination. Lessons 4 and 5 were all about that. Very precise turn coordination. Setting a bank for a turn, but making sure the nose stays fixed to a point on the horizon until the bank is complete. It's harder than it sounds. In the Cessna 152, you can forget you even have rudder pedals, except when you need to do a slip, which you never really need to do since you have flaps. Anyway, in the Citabria, unless you coordinate an aileron input with rudder, the nose will actually yaw (very substantially) in the opposite direction of your input; bank to the left, and the nose yaws a good 20 degrees to the right, opposite the direction you want to turn. The reason for this is that to bank an airplane, you're decreasing lift on the wing that you're lowering and increasing lift on the wing you're raising. Decrease lift, decrease drag; increase lift, increase drag. The drag differential causes the airplane to yaw in the direction of the highest drag. But...
