If I have to turn on the oxygen at 5K, I'm going to have to do it in the truck on the way up the hill to the airport. And keep it on the whole time I'm there. Airport is 6K and our takeoff is typically at 9000 ft density and can be 10K. 5K may make sense if you are a retiree living at 20 ft in Florida, but it lacks both practicality and necessity for everyone in every situation.

Don't worry about the density altitude, as your lungs respond to actual pressure,
unlike a carburetor.

I have a very large oxy bottle and always start oxygen at ground level. Ive noticed a reduction in fatigue and improved concentration.
5000ft might be OK, but I would rather spend a few bucks on oxy and be right at the top of my game all the time.

As someone already stated settings the MH to 5000msl uses negligible amounts of 02 even up to 10,000msl.
The cost is minimal and the benefit for some maybe huge....

I set my O2 to ground level yesterday and the density altitude was above
9,000' when I took off.Â* Still had a ho-hum flight.Â* At least it was
cool at 16,000' MSL.
