It also uses less fuel as it’s generating lift though forward motion not just by bashing at the air.
I too ANAHP but I’ve had a couple of ‘fun’ lessons, if you take your hands (and feet) off the controls you will be spinning into the ground in short order. If you’re lucky you’ll land the right way up.
The sensation of using collective is a bit like keeping a broom balanced bristles up in the palm of your hand. It will stay upright but you need to make constant little adjustments to keep it up. Then you’ve got the pedals and collective to keep adjusting as well (for the helicopter that is, not the broom).
Tying a rope an climbing down is not an option. Get a balloon*.
No. I thought that you might be able to let go of the collective but was corrected by a real chopper pilot who pointed out that if the engine fails you have to back off the pitch of the blades** pretty damn sharp or the rotor will drag to a stop leaving you with no lift. So just ignoring the collective is not possible either.
*Waiting for a balloonist to chip in that this isn’t realistic either.
**I don’t remember the terminology.
