Dec 16, 2022 at 7:46 | comment | added | Jpe61 | @AirCraftLover forces involved with aircraft pedals is very different from that of a throttle or brake in a car. Also switching between pedals in acft would be a huge risk, imagine pressing the wrong one... | |
Dec 15, 2022 at 15:15 | comment | added | AirCraft Lover | @Jpe61, yes, exactly. Yaw left and yaw right will be done in different time and never be at the same time, so why must need two pedal? Just like automatic transmission car, it just involve right leg only so reduce fatigue of the driver. The same way should be able to be done with helicopter. | |
Dec 15, 2022 at 15:11 | comment | added | AirCraft Lover | @AdityaSharma, automatic transmission car just involves right leg to control throttle and brake as they work different time. Yaw also work in different time. Please be noted that pedal is tool for yaw, not to make turn. To make turn during fly is using cyclic. To make left turn, cyclic is left, to make right turn, cyclic is right, the same way to do moving forward and backward. | |

Dec 14, 2022 at 10:48 | comment | added | Aditya Sharma | @CarlBerger Theoretically, it is possible, but for something as critical as yaw control, you definitely wouldn't want having to constantly manoeuvre your feet around the pedal. It would be difficult to control it precisely, and not ideal when you need to make a sudden input in an emergency. :) | |
Dec 14, 2022 at 10:48 | comment | added | Jpe61 | @AdityaSharma one could easily make a pedal which can be pulled. Older bicycles had these for example. | |
Dec 14, 2022 at 10:39 | comment | added | Apfelsaft | of course you can pull a pedal - see bike pedals other than platform: eg clipless or clipped. Also e.g. gear shifting on a motor bike is done pushing and pulling the lever using the left foot | |
Dec 14, 2022 at 10:35 | comment | added | Aditya Sharma | @Jpe61 You can both push and pull a stick, but you can only push the pedal, not pull it. | |
Dec 14, 2022 at 10:33 | comment | added | Jpe61 | On the other hand: single stick controls four directions in that sense, with no problems. | |

Dec 14, 2022 at 1:57 | comment | added | Aditya Sharma | It's simply more intuitive to have a rudder pedal for each direction. If you suddenly have to yaw left, what is more intuitive? Wasting time deciding weather to press or release that one pedal, or just flooring the left pedal? | |
Dec 14, 2022 at 1:51 | comment | added | Aditya Sharma | @AirCraftLover I fully read your post. Yes, it's possible to have just one pedal control the yaw. By that logic, you can bias the rudder of an aeroplane in one direction, and then you only need one rudder pedal! But imagine how ridiculous it would be to have one rudder for two directions, plus you will have to press that rudder all the time, which won't be fun. | |
