YOU'VE BEEN FLYING AT THE WRONG ALTITUDE THE WHOLE TIME!!!!! 

My weekly dose of philosophy.

GPS may be accurate or not, but it's not the standard way of handling it which seems primarily concerned with keeping you above terrain and not crashing into other aircraft. Can GPS be wrong? If anybody is in the air and has both values on their cockpit but doesn't know which one to "trust" it's a big deal, as the chart at 20:39 shows.

OK here we go: Just will be with voice dictation so just ignore all of the typos for Apple does not know an airplane from a hole in the ground. First of all how does your traffic control know how high you are. These days we use a Adsb automatic dependent surveillance broadcast. The airplane puts out its pressure altitude. Pressure altitude the literal air pressure at the altitude you are at. Turned into feet above sea level on a standard day. And either the ADSB system on the airplane or the system on the ground in the controllers computer makes little adjustments for barometric pressure. That is how they know how high you are. Certainly ground level has nothing to do with it. I do not technically need a generator and an alternator but if one breaks it will be nice to have the other! So one is just a back up that's all there is to it. The airplane does not have an auxiliary power unit it is too small for that. Hack the auxiliary power unit in an airliner is probably about the same size as my engine! So I start with the battery. If my battery is ever weak I asked for what is called a ground power unit. This is where a guy at the airport Drives up in a golf cart towing a generator. The generator is probably a good solid 50 hp or so. It is a pretty big heavy duty unit. It probably puts out maybe 50 times the horsepower that I need. It's made for business jets and stuff. Anyway it gives plenty of amperage to my airplane when I plug it in. So even if my battery is weak the ground power unit gives me plenty of juice to start. Here's the thing: the ground power unit plugs in about 5 feet behind the propeller of my airplane. That means the poor guy has to plug it in right behind the propeller when it is stopped which is fine, but after the engine is started that propeller is obviously insanely dangerous and the poor guy has to get within about 5 feet of it to unplug the ground power. Nobody likes this. Next is something about an air compressor. No I do not use air compressor for start to start is done with the battery spinning and electric motor for sure electric motor spends up my gas generator. No air compressor there. Synthetic vision is simply an image of the terrain that has the elevation of the terrain to hopefully stop me from running into it. My data happens to come from Garman who gets it from some other source. I think most people use the SRTM database. This is a database collected by the space shuttle. The space shuttle went round and round the earth with some radar antennas stuck out of the cargo bay measuring elevation. Interestingly some fuel cells failed on that mission and the astronauts actually stayed up there without enough water or electricity so they could still finish the mission and map the planet earth for us. No experimental airplane is really going to get certified. The epic LT is an amazing experimental airplane that got certified but it took so many years and so much effort that the certified airplane really might as well be a different airplane. Yes the airplane does have reverse thrust I simply aim to propeller to a negative pitch. I get negative thrust that way. The propeller always turns in the same direction which is clockwise, but the propeller pitch just adjusts to give negative thrust to slow me down. You could go your entire life in this airplane without touching the brakes if you were simply careful with your landing procedure.

MSFS doesn't seem to have a very good flight model yet. Altitude deviation due to temperature is way down the list.

Just an airplane on a taxi way.

Oooooooooooo good question! Problem is gps can be blocked and jammed and fail. Air? Not so much.

Austin Meyer I already saw that video , so i guess gps is not so reliable, maybe in the future

I agree with you

at or about 18,000, actually

YOU WILL! It will be in the mobile version first.. being worked on right now, actually!
