Default 737-800 cruise speed
why can I only get it to mach 0.84 (actually 0.82 if you want t stable flight)? Isn't the top speed a lot higher than that? And why does the plant become unstable when I reach the 0.84 top speed? and can someone explain a bit about the engine color in the panel? thx :P

and it seems like I can go faster with IAS speed display, so can someone explain why mach is included? Sorry I am new.......

NVM, just saw the true air speed which I believe is right below instrumental speed.....but, still, why can I dial up the IAS to speed faster than the speed dial for mach?
Above roughly 26,000 feet, you use mach over IAS. The reason being is because as you climb higher, you may notice that although your IAS remains the same, your ground speed is actually increasing, due to the lower air pressure pushing into the IAS probe. The error in this value is also increasing - that's when mach comes into play. It stops the aircraft overspeeding and effectively acts as the IAS - only more accurate. When the mach and IAS speed are equal to each other, you'll be between 24,000 to 29,000 feet, and the aircraft may or may not automatically convert to mach speed. If it doesn't, CONVERT IT TO MACH. The same thing happens as you descend. When ascending at a mach speed, you may notice the IAS speed decreasing. This is normal, as the air pressure continues to drop, but you shouldn't rely on it when using mach anyway.

The top speed of a 737-800 is mach .82, hence why your aircraft goes awry above this speed. Always know your aircraft speed limits.

If I'm at FL350 doing 310 knots it shows as .9 mach.
.9 mach translates to 595 knots
If i'm 600 NM from my destination, will I reach it in 1 hour or 2 hours?

.9 is too fast. But to answer your question - it will take one hour, because you would rely on ground speed - 595 knots - to calculate the rough time remaining.

A calculator that u may or may not find useful

That's not the point. The point is that if your speed is 300 at FL350, that equals about 600.

U asked how long it would take, 1 hour, use the calc bud its y i posted the link to help so u can work it out, Remember u r using ground speed not KIAS or TAS

Try Zibos 737-800 Mod. THe Default 737-800 are very bad...

What's wrong with the default one? I'm noob, explain please :D:

It has many Bugs and its not so realistic

Is there a list of these hings? I really would like to know.

So what's wrong with default plane then? :D:

The default plane lacks a lot of cockpit functionality, doesn't have a cabin, and uses default X-Plane sounds (for now, anyway). It's more useful for the devs to build these incomplete planes to add more so-called datarefs to X-Plane, which others can then use to make their aircraft more compatible with X-Plane.

The EADT 737s were an excellent choice in X-Plane 10, but the new 700's FMC doesn't work, and the 800 isn't yet compatible with X-Plane 11, as far as I'm aware. Both aircraft are free and better than the default, but don't forget to RTFM.
