Which control do you use to fly the helicopter in pretty much any direction? The cyclic - it has far more authority than the TR..
Far more authority, yes. However the tail rotor can still add some more. This isn't an either / or call, it is all about adding more. Even if the TR can only add 10% more, that's a whole lot better than 0% more.
Did you ever turn down a 10% pay rise on the basis that you already earned far more than the pay rise being offered?
If the IAS is so low then full pedal will create yaw but not much else - the main movement will always come from the cyclic input..
The TR is the sole cause of translating tendency. Yes, it is INTENDED for yaw, but without question, it causes translation too. Are we saying the cyclic alone is so very powerful by itself that there is no need for any further assistance from wherever that help might come? If that was true, we wouldn't even be discussing escaping VRS ASAP with minimum height loss as by definition, the only time nil further assistance is required is when we can already do it with zero height loss using cyclic alone. That clearly isn't the case.
Far more experienced people than me dismiss the Vuichard technique as window-dressing for IVRS recovery which can be achieved just by raising the lever.
I didn't even consider that to be a possibility!
