Tail Take Off
S-61s were only to be found in cold places in my day
What about our BHL (Became MHS in 83) machines in Kuala Trengannu Lah?
Admittedly they only survived because the average Malaysian Oily weighed about the same as the left thigh of his North Sea counterpart but still "Queen of the skies" in their day!
We used to use a Performance Graph called "Modified En Route Group 'A' with fuel dump" to allow us to fly after lunch!
I remember young (he was then) Tony Coleman taxiing out from the KT ramp all the way down to the other end of the runway unaware that his National Co Jo had actually turned the fuel dump switch to the ON position during pre taxi checks (rather than confirming it in the OFF position)
Pre Take-off checks revealed a fuel state of 300 lbs and a very impressive stain caused by the other 2700 lbs dumped along 5000 feet or so of runway
