I’m sorry my post didn’t have pictures.

Maybe BeerVenture can countersue because they don’t want anyone to confuse AirVenture with BeerVenture. They both just took the word “adventure” and changed the beginning, like probably many other businesses. Not sure if the law here but seems to me if EAA wanted a rock solid trademark a little...

She probably has a name. I understand all in good fun but the number of comments is a little rough. No confusion why there are almost zero women pilots.

That's great, part of the problem is the leases are so bizarrely cheap no one ever gives up their leases. Our hangar neighbor at APA is a 3D printing business that as far as I can tell has nothing to do with airplanes. Another guy has a bunch of old cars.

I ended up in a 340 partnership, but will send contact info in case something comes up. Hangars are almost impossible, and Jefferson county and APA seem resistant to building any new ones, which is a shame.

WAAS ground reference stations simply measure the error between where they are and where GPS says they are. This correction is then send via a ground network to the master stations on each coast, which relay these corrections to the stationary WAAS satellites (there are currently 3), which in...

Most GPS units (at the least the Garmin units) have a dead reckoning mode if GPS signal is lost to do the math for you. I was kidding about the Sextant but early airliners had a hole in the cockpit ceiling for just that.

There’s always the Sextant. Doesn’t work so well in IMC though.

They are increasing the VOR service volumes for the remaining MON VORs out to 70nm down to 5,000 ft (low and high), and similarly they would enhance the existing DME network by decreasing tolerances, changing the signal shape, adding more DME stations, and possibly increasing signal strength in...

It is a standard WAAS ground reference station, my understanding is master stations uplink data to satellites and wouldn't be relevant to WAAS coverage. There is WAAS coverage in Hawaii but with only one station I believe it does not usually provide sufficient ionospheric corrections for an LPV...

There actually is a WAAS ground station in Hawaii, next to the runway in Honolulu too so probably get sub meter accuracy on an approach already.

You could eBay them and buy new used ones on eBay. Not free, but you’d only be out eBay fees and shipping.

The DME network would replace VORs, so I’m sure MRAs would drop, although I don’t know of an airway with a 10k MRA in a flat area. NDBs can’t be used for RNAV, so if the goal of GPS jamming is to cripple our air infrastructure, they would succeed with only an NDB backup network. Don’t get me...

Not really, just for training and practice NDB approaches, although not in awhile. There are still some Romeo airways in Alaska, I don't think there are any in the lower 48.

NDB doesn't make sense even if we had them. It's not accurate enough to use as RNAV, so you'd have to install thousands of transmitters, and even then it's not accurate. There is no case for it. The DME network already covers most of the US and is used by transport category airplanes already...

If my geometry is right, if you have two in range that are both exactly 60nm apart you’d be able to tell where you are in a diamond shaped polygon something like 36 square miles in size, or potentially much worse if the geometry was poor or there was interference, or less depending on how far...

NDBs can be off as much as 5 degrees, which is an error of 6nm (31,000 feet) 60nm out. DME could be tweaked to be less than 100 ft, two orders of magnitude more accurate, and with only one NDB you don’t know how far away you are or really where you are. NDB is also subject to many difference...

The FAA has been studying what makes the most sense as a backup for many years under the Alternative Position, Navigation, and Timing (APNT) effort. VOR MON is really left in place for GA– transport category will use IRU and DME-DME in the short term and other solutions are being looked at to...

I got a response this morning, NOTAM was updated and showed up in ForeFlight about an hour later: Your Aeronautical Inquiry has been closed. ======================================================== FAA Response: Hi John, The NOTE will be removed as soon as possible. Thanks...

Those are not criteria for prohibiting a PT.
