Xavion version 2.91 Release Notes


3-D instrument approaches are now back!

The FAA discontinued some data needed for 3-D instrument approaches, so this update gets that data ANOTHER way to keep bringing us those very very useful 3-D approaches!

Remember, in Xavion, you just touch one button to load an approach, and once you've done that, you get 3-D hoops for from where you are to the IAF, through the whole approach, and even the miss and holding pattern!

This is by far the easiest way to load and fly an instrument approach that I have ever seen... it makes them as fun and easy to fly as the next-gen Highway-In-The-Sky concepts we are seeing!

The winds aloft forecast was previously scanned incorrectly... that is now fixed!

Let't talk about cabin altitude: Cabin altitude is clearly defined as a pressure altitude, based on standard barometric pressure setting of 29.92 inches of mercury and 15 degrees C at sea level.

So if a given pressure in the cabin is 8,000 feet of cabin altitude, then the pressure is what we would see at 8,000 feet ON A STANDARD DAY! This is the pressure pushing OXYGEN into our LUNGS!

But we don't usually FLY on standard days, so an 8,000-foot cabin altitude does NOT mean that we are 8,000 feet above the GROUND! Differences in baro pressure and temperature change that altitude, which is why we enter baro pressure into our airplanes every time we fly.

So how do we reconcile these two completely different needs for cabin altitude: one to be UNCORRECTED to show us actual oxygen pressure on our lungs (!) and one to be CORRECTED to show us height above sea-level?

The answer is:

Go to the diagnostics screen: You will see the CABIN ALTITUDE in the upper-right area of the window. This is for STANDARD ATMOSPHERE, UNCORRECTED. This is the actual pressure acting on your body right now.

If this is more than 12,500 for more than 30 minutes, you need oxygen.

If this is more than 14,000 ever, you need oxygen, NOW.

THIS is what you use to make your oxygen decision, especially in pressurized airplanes.

Now, go to the PFD on the main screen: If you are in an UN-pressurized airplane (as set in aircraft setup) and don't have an iLevil with pitot-static ports, then Xavion will use your CABIN ALTITUDE SENSOR, but of course CORRECTED FOR BARO PRESSURE AND TEMPERATURE!

Look at the baro pressure, if it is not exactly 29.92, and you will see that the PFD is indeed showing an altitude offset from the cabin altitude by about 950 feet per inch of mercury!

Nice!

Now want to have some fun?

Go outside to get a good GPS signal and then go to the aircraft setup and tell Xavion your airplane is PRESSURIZED.

Now, of course, cabin altitude in a pressurized plane is useless for seeing how high you are, so Xavion will use GPS for your altitude on the PFD!

See the label up above the altitude... it will switch from CABIN ALT to GPS... and, if Xavion has gotten a correct baro pressure from the net, then the altitude tape won't move very much!

You will get almost the exact same altitude from your phone or ADSb receiver pressure sensor as you get from your GPS: Both are corrected by all known technology!

OK if you are like me then you will forgot precisely all of this the moment you have to keep an airplane right-side-up, so here it is simple:

The cabin altitude shown in the diagnostics screen is the pressure in the cabin: Use that to tell if you are safe to... BREATHE!

The altitude shown on the PFD is corrected for everything we have: Use that to... FLY!

Just be sure to set whether or not the airplane is pressurized in the aircraft setup, and get yourself a nice ADSb receiver so Xavion grabs the local baro pressure from ADSb in flight, and auto-loads it into the system to apply it to your altitude on the PFD!
