Why do choppers fly so low?
Recently I was on a chopper out of Grand Canyon to Bar 10 Ranch, AZ. Both choppers (Bell 206) that took our group out flew very low, maybe 30-40 feet AGL. Very exciting. Why do they fly so low?
NB: not a complaint; as a crappy fixed-wing pilot, I know zip about choppers.
Thanks.

There is no issue with height velocity curve in the cruise .... especially in the 206 . It is mainly relevant for very slow flying or hovering as you have to trade height for speed ..... if you are going faster you already have the speed and can actually trade some speed for more height even with no power . Anyway , I am sure they knew what they were doing !!

Sounds like a bunch of cowboys to me. (Maybe thats why they were going to the ranch!)

It is easy to say it is a non-event because the curve says its fine.
Pulling it off over uneven, rugged terrain could be an interesting experience.
Apart from a fear of heights, they fly low because it is cool and creates an experience, not because it is wise to do so.
We don’t know what terrain they were flying over . Are we now all saying that flying at 40-50ft is unacceptably dangerous ? I accept that 2-300ft would be potentially safer but then 1,000ft would be safer than that .... maybe it should also be in a twin to make it even safer ? What they should really do is put a strip in at both ends and use a plane ... that would be even safer .
Thats something we would not even have done in the military.
It was called "Contour Flying" and was a standard technique done by the US Army.

I am sure that we have all indulged in a bit of low flying at some time. But having had a scare on my very first helicopter flight (in a Bell 47 with no doors on when the pilot put in an unecessary steep banked turn without telling me) I always ask my passengers if they want anything other than a nice, gentle, scenic flight. If one of them looks nervous then I fly carefully. I have heard so many tales from people who tell me horror stories about their first (and only) helicopter flight when they were scared witless by some moron of a pilot showing off when they only took the flight to get a better view of the scenery.

A fair few operators (everybody I've ever worked for) have minimum en route altitudes that vary from 300' to 1000' AGL.
Over the decades of my career, I've asked pilots why they fly low and gotten answers like 'why waste time in a climb?' and 'I want to be low in case of a main gear box emergency.'
Me? I want to see more than you can see flying NOE or contour or whatever you want to call it. My rule of thumb was a hundred feet up for every minute en route.

Maybe I should mention that Whitmore Wash, where we left the Canyon, is about 2000' AMSL, while Bar 10 is I think 4100'. So they do some climbing in this 8-minute trip. Also they do it all the time so they're v familiar with the terrain. They didn't particularly strike me as cowboys, and I've met a few in my time in aviation. But of course I know zip about choppers.

In my experience most nervous passengers are much happier flying low ...... also there is no indication that they were throwing it around ! Some on here will just criticise for the sake of it .... usually making some point about their superior mil training !! ( not however so far in this instance!)
