High Altitude Alert
This airport is at 7135 feet, so be on the look out for density altitude.
Coming from the West
🔼 Valley of Yosemite as seen from the sky
Yosemite National Park is on the west of the pass so I made a detour into the valley to enjoy the view.
🔼 My flight path eastbound towards KMMH
Afterwards, due to the rapid rising terrain, I climbed all the way up to 13500ft for passing. There are some gap and valley that will allow you to go a little bit lower but I much prefer to be above the valleys here to keep my options open. Once you passed through it, you should be able to start your descend quickly and prepare to enter pattern to KMMH.
14 CFR 91.211 Oxygen Requirement
Remember that at those altitudes, oxygen might be required depending on how high and how long you’re flying:
- >12500ft & >30mins: Crew needs to use supplemental oxygen
- >14000ft: Crew needs to use oxygen for the entire duration
- >15000ft: Crew & passengers needs to be provided with oxygen
… and note that those handheld oxygen can most likely does not meet the requirement.
Parking
I did use the FBO there and they do have a tie-down fee for day visit / transient that is waived with fuel purchase.
Departing
Sicne I need to climb back up to 12500ft on the way back from 7000ft. I extended my downwind into the lake and then did my climb there as I made a U-turn back northbound. Since this was in September, the climb rate was not too terrible but otherwise over the lake might be a good area to circle and climb. Finally at the cruise altitude, I turned westbound north of the town of Mammoth Lake and roughly follow the V230 back.
