Frozen Bottom Sledding Club

colder than a dead witch's tits,
in a brass bra,
on the shady side of an iceberg.

Alaska, the final frontier, home of the Frozen Bottom Sledding Club, [Ultimate Glacier Pilot (UGP)]

Okay, this is a little confusing but I'll do my best to explain how this works:

All of this falls under the Frozen Bottom Sledding Club but you'd still fly for HBRC.


One of our networks includes several of our own FBOs, off-airport glacier strips in Alaska (based on the formerly payware Ultimate Glacier Pilot for X-Plane 10) and the FSE FBOs that those strips are closest to.


The files within that package are pretty self-explanatory. Read it. It's too much to explain here.


When you start or end a flight, FSE's server doesn't verify that you are actually at any specific FBO/airport. Instead, it takes a snapshot of your current coordinates and finds the FBO that is closest to you. It looks for the airport center that's closest to where you start/end your flight. That usually matches the intended FBO, but sometimes one of two anomalies result:

  1. Like our FBO at KNRA Coupeville NOLF, sometimes you're on the correct runway but the nearest airport reference point is at another airport (ref. KNRA glitch and ​also FSE Manual’s ref.).

  2. You might be 1000 miles from the nearest airport, in the middle of the ocean, but if your fuel reasonableness checks out then it's as if you flew all the way there.

The second case is where this works. We figured out which FBOs are closest to each UGP glacier strip, built some nearby FBOs (mostly 1-lot, one 2-lot) and pointed them there.


Instead of flying to the FSE-destination airport, you'll fly to the glacier strip in a bush plane. FSE will recognize your landing at the glacier strip as having arrived at the FSE-destination airport shown in the "Cargo" assignment template.

How it works:

  • Select the FBSC FBO that you want to fly from.

  • Select the plane that you wish to use (you'll know it's ours by the FBSC- prefix)

  • Grab the job(s) that you want to fly.

  • As to which glacier strip you'll fly to, that's built into the "Cargo" assignment template. For example, you might pick up the jobs at PATW Cantwell, pictured here:

  • For coordinates, reference this page, or click on the glacier strip tagged in HBRC's Google Map, or reference the list in the UGP package.

    • i.e. "UGP UX07" Thunder Glacier, 62.92813, -151.12285

    • i.e. "UGP UX02" Pika Glacier, 62.96828, -150.74876

  • Fly them from our FBO (i.e. PATW Cantwell) to the glacier strip.

  • At the designated glacier strip, FSE will recognize you as being at the FBO most closely associated with the coordinates of that strip, the one listed as your destination on your "My Flight" page (i.e. 33AK Nugget Beach).

  • There, you can pick up those job(s) and bring them back to the FBSC FBO of original departure (i.e. PATW).

    • for the return flight, disregard the "UGP UX--" cargo assignment, just bring it back to the destination listed, where you originally left from.

Our various FBOs are stocked with Cessna 185s and Piper PA-18 Super Cubs.

Have a look at our FBO map here:
The teal-colored FBOs in Alaska are owned by FBSC, the grey ones are not owned but in most cases they are the FBOs that FSE will recognize your flights terminating and/or originating at.

Here is a list of:
