Two flight instructors, with together more 8000 h on helicopters and more than 4000h only on Bell 206 on a checkride. Big airfield for us alone. Let's going to see an AR not the normal (entering, hundreds of time practiced and teached) way ... Simulated hostile area take off, light a/c, in 400 ft ground, IAS 50 kt, climb rate >1200 ft/min, 100% Nr, rolling the engine to idle. Great astonishment on the next seconds about what happens. Rapidly decreasing NR (<90% initially), immediately audio warning, in line with the same way, rapidly decreasing IAS (<35 kt). Lowering the pitch to hold the Nr decrease, pushing the stick to get some IAS and to level or nosedown the helo.
First impressions on our mind to get low G, MR vibrations. Never experienced bad a/c control (aerodynamics and it needs time to establish the AR airflow on the blades). Really impressive descending rate.
Pushing the stick and making airspeed decelerate Nr (on AR transition, also aerodynamics) and a light a/c on AR with complete downed pitch (without flare) works hard to get some extra MR rounds.
What is to do? Flare for Nr, or going for 50-60 kt AR Speed?
Seconds running away, good old earth, we are coming...
Story ended in the badest AR touch down, i have ever made with a very long running distance on the ground and praise the lord and the light a/c, without any a/c damage. (Nr all the time no more than 95%, landed with leveled a/c, IAS 35 kt, and skidding on the ground)
Eye to eye view between us, never, never on that way...
Hey all you single engine helo drivers! On how much missions you have started the flight with an equal entry situation???????
How much pilots makes thousends of hours around the world alldays within the "dead man". Longlining, cropdusting, seismic or measuring missions,....,.....,.....,.....,............... ???
But don't worry! Flying is leaving the ground with technical assistance. And how much important parts could fail on a helicopter

?
(Only gearboxes, drive shafts, controls, engines, blades, fuel systems, ignition, hydraulics and some other parts ...........
And unfortunately tec failures ar not the specific dangerous part of our job
If your mind is blocked now, stay on the ground and start a career in a tax office! But sometimes you have to drive a car and the brakes could fail.....
