Why do many pilots refer to the pedals as rudders?

I have mainly heard them being referred to as a singular rudder. As in "...step on the rudder...". My favorite is when they are spelled peddles.

I did a search on this forum and 'rudders' is used freqenetly by many members here.

  1. Why do so many speak of rudders?
  2. ...You would also want to add a brake handle on the stick and a throttle control on the handle for the rudders.
  3. ...We all know how CTs love their rudders, so think about that wombo combo. But I still flat out enjoyed rising to that level of skill that I seriously doubt could be replicated in a 172. Finally, if you have arthritis or back issues, it's a lot easier to get into a CT than it is to climb up on a...
  4. ...If one needs to engage the rudders quickly and firmly, one is pushing with the bare foot, but it's certainly doable. I can slide each foot back into the shoe easily without using my hands. As far as bladder relief, find your nearest glider port and go down and have a chat with them. Many gl...

    ...This plane as a ton of adverse yaw and I feel I rely pretty heavily on my rudders.
  6. ...danced the rudders, got on brakes quick, then "flew it" to the fuel pump. Next hop to MI had same strong surface winds, so with my strip being a 9/27, I put it at county airport with a 18/36 and had my first grass strip touch down right into the wind, felt good. I'll admit I was a lazy C-150 pilo...
  7. ...I would not wiggle the rudders. That will alternately un-port the "nipples" on and off giving baby GAS!! and in the plane that is not gasoline. You will be sending air pockets down the fuel line and at some point might actually kill the engine. Just a little steady rudder in the proper direction to...
  8. ...I wonder if just wiggling the rudders back and forth while level would even things out? Great post thanks! Dave
  9. ...Fuel transfer is conducted by the proper use of the rudders

Just the same as slang used in many areas in life. We call our ignition system check a mag drop. We used CDI's and not mags a.k.a. magnetos. What's the difference as everyone knows what another is referring to.

Owners us the word stab a.k.a. stabilator, but we know what they meant. There are many things like this.  It doesn't make any difference so long as the person you are talking to knows what you are referring to.

Roger, the power for our ignitions comes from a permanent magnet generator, so by definition they are in fact magnetos. They just aren't the typical type on magneto used on non Rotax powered GA aircraft.

Generators and alternators are not magnetos. They supply power only. They have different workings. Our ignition is CDI (capacitor discharge ignition). They work nothing like a magneto. The generator in the rear is not our ignition system. It only supplies power for the engine an accessories.  The generator on the rear of the engine does not dictate the firing order nor does it regulate the timing of  3 degrees ATDC for starting nor does it dictate the 26 degrees BTDC. (soft start timing).  Apples and oranges. If we had magnetos Rotax would say so and it wouldn't be on one of their service test questions. Call Rotax and ask them where our magnetos are.

Plus we aren't talking about what we have, but terminology on things like rudder peddles, ect... Our CDI ignition sytem gets refered to as a mag check the huge majority of the time. It's just an old school hold over.

You could call it a CDI check for now on.

Mag check, stab/stabilator/elevator, ...etc sound normal to my ears but rudders make me think I'm missing something, that the speaker knows something I don't, just sounds wierd to my ear.

Roger, a magneto is a generator! Take the time and look up the definition of a magneto. While our ignition is not all contained in one unit like a Slick or Bendix magneto, they still get their power from a permanent magnet generator.

So this comes down to how things USED to be called, vs how common language has evolved. Tom is correct, a magneto is a permanent magnet generator. We call aircraft ignition magnetos just "magnetos" as such, for those that have bendix or slick magnetos, because they have spinning coils and permanent magnets.

The CDI are powered by magneto generators. You could call them magneto dynamos, or permanent magnet dynamos, or whatever else too.

But it is indeed still a magneto generator.

Sort of like how things used to be called "high tension" is now "high voltage", and "condensers" are now "capacitors".

Roger is correct though that this gets into a level of semantics thats unnecessary... usually. Though my engineering brain says it would be better if everyone kept using a single word instead of changing it up... Operating on different levels of semantics are where confusion comes from. There's a reason why science and law loves to use latin terms.... their meanings don't change.

PS: @Ed Cesnalis you took a screenshot of my plural "rudders", but I said that in regards to the plural "CTs", not a singular one. So I get a pass !!!

We're still off subject of rudder's and pedals.

You can blame all this on the American way of turning proper and accurate wording into slang wording. It's in everyone's daily lives.

And where do you think we got off track? Besides getting off track happens all of the time on this forum, and has never been an issue before.

Choke vs enricher circuit, stab vs stabilator vs elevator,  nose wheel vs front wheel, cylinders vs jugs, compression test - static or differential, ballistic parachute or chute, cooler vs radiator,  tire or wheel and the list goes on and on. It's all in our own individual vocabulary, where and how you learned describing words.

So we all I'm sure know what peddles vs rudder pedals mean when talking about a CT.
