That horse was dead after the first beating. No kidding. For John (because I know he's going to now give me a lecture on how a Cessna steers again) ... here's some info that will maybe clear up our disagreement. This is for a Cessna 150 but it also applies to the 152 and the 172. They all operate the same way. Pertinent excerpt: ".... Tricycle aircraft will align with the direction of travel if weight is kept off the nose wheel. There is a significant design difference of the nose wheel between Cessna and Piper. On the ground, Piper steers heavily and positively; Cessnas have springs that will gradually pull the wheel into the turn. The left and right turning springs of the Cessna are usually of different tension. This means that more differential toe braking will be required in one direction than in the other. (Note by me: There is no direct connection of the nose gear to the rudder pedals on the Cessna. They are spring loaded.) The Cessna's nose steering is coupled to springs, and it's only movable 10 degrees) either side, unless differential braking is used. Braking will then caster the wheel to 30 degrees." http://www.pilotfriend.com/training/flight_training/fxd_wing/cessna150.htm In addition John: When taxiing on the ground you can turn make turns (although they tend to be wide) using rudders only but the turn is because you have deflected the rudder to one side. By adding some throttle, you cause the prop wash to hit the deflected rudder which pushes the back of the airplane in the opposite direction of the turn. That causes the front of the airplane to turn in the direction you desire to go. The spring loaded nose gear simply allows the tricycle landing gear to follow the turn. For sharp turns, you use differential braking. Very interesting. Thanks! Helps explain why they make steering rods for the Cessnas. Some of the RC planes with a turnable nose geer also turn with rudder action. The physics are basically the same as in the above paragraph, but without the differential braking. Although, the bigger, more expensive planes have brakes, so they may also use them for steering. I don't have one of those several thousand dollar jobs. -- Guns don't cause problems.

The JohnnyMop flushes his head....
" I've been told to give it a rest even though Don is the one who *didn't* give it a rest. It's the city's job. " Johnny...stop this conduct unbecoming an officer in the US Army. You are embarrassing yourself. |
