Re: Mountain High for Built-In Oxygen System
I think that's for the 4-seater DA42. The tank for the DA62 is larger with 77 cubic feet.

Re: Mountain High for Built-In Oxygen System
Computed from the O2D2 manual, consumption at 15,000' is 1.2 cu ft / person / hr. So...
42 built in: 50 cu ft / 1.2 = 41 person hours
62 built in: 77 cu ft / 1.2 = 62 person hours
10,000': Consumption is about half
18,000': Consumption is about 30% greater
Further calculations are left as an exercise for the reader!

Re: Mountain High for Built-In Oxygen System
I've also become a huge fan of the MH O2D2 system. It came with my 2018 DA42 (which does not have installed O2). I usually strap the O2 cylinder to the back to the passenger seat. The O2D2 is attached by velcro underneath the instrument panel. I've found this to be a convenient location.

Re: Mountain High for Built-In Oxygen System
That is exactly where I have mine mounted. Thanks for posting a photo.

Re: Mountain High for Built-In Oxygen System
I have a 50 cu ft MH tank strapped into a fiberglass cradle mounted in the nose compartment. This is the same cradle used for the factory installation using the Aerox tank. The MH regulator has two feed nozzles so I have two lines leading to two controllers, one mounted next to the left seat and one next to the right seat. The system works fine.
