Some of you aren't listening are you?
A fully developed VRS stipulates that cyclic/collective*/yaw inputs are redundant. Do you know what that means guys?
It means that you - the pilot, inputs at the cockpit end but nothing is registering at the aerodynamic end.
Once more for the hard of hearing:
The aircraft no longer responds to your demands.
How, therefore, can you recognise you are in fully developed VRS and then at the flick of a switch (cyclic well fwd) withdraw from VRS?
You can't, because it won't! It will either run out of altitude, or fly itself out of VRS (if it remains upright).
Make NO mistake here. There are only two remaining types of pilot who "demonstrate fully developed VRS".
(a) The majority of them are actually only demonstrating IVRS and genuinely believe it is the real McCoy.
(b) The remainder - actually do demonstrate fully developed VRS and are lucky to still be alive.
IF you had mil training in the 50's and 60's, you may have been lucky (especially in the RAF) or should I have said unlucky, to have been shown fully developed VRS in the Sycamore/Whirlwind. These instructors commenced the manouevre at between 10,000 and 12,000 and often pulled out around 3-4000 feet
{* The collective is the only way out of VRS - by entering auto the VRS is removed eventually from the rotor plane. The problem with this is that the a/c still has to be upright! And you will have to accept an even higher RoD as auto takes effect. This is the only way out of VRS}.
No-one should ever be in a helicopter attempting this demonstration below (IMHO) 5000' and upwards.
It is my experience that very very few civilian pilots fully understand VRS or have even experienced IVRS.
Please try and get your heads around this for your own sake and those around you who are passengers at the time.
