QNE, QNH, QFE

Speaking of QNH, QNE and Transition Altitude and Transition Level, my reminder is that "A" points up so you sent QNE climbing through Transition Altitude, and well, you set QNH descending through Transition Level.

When I used to fly in Kuwait back in the day, TA was 3000' and TL was 5000', or FL50. Below those, we were required to set QFE. So climbing past 3000', you switched to QNE, then descending through 50, you went back to QFE. Don't know whether that has changed or not since then, as it's been nearly 20 years.

Moscow still does it this way. Of course, you also get to transition to meters below TL/TA so we've got that going for us. I believe China also uses QFE and meters all the way.

This never fails:

"Buenos dia Merida Center, Amflight yada yada yada flight lev...correction, level one eight thousand"

Uh, hmmm...I think you're backwards, unless I'm reading this wrong... It's go home day tomorrow though, and I'm already mentally home, so I could be wrong.

China is all meters. Most of the big int'l hubs use QNH

He's correct. Use TA on the way up, TL on the way down.

This is all pretty ingrained these days, but I remember at XJT most of us going down to Mexico having no idea the difference between the two.

"So uhh, this says Transition Level of FL195...should we go to local altimeters there?"
"Eh screw it, let's just do it at FL180."

Hopefully they addressed that in the training dept. :)
 
Thanks all. It's one of those things that I get it when I see it but I don't know it enough to teach it, which always bothers me.

Never mind, i just reread what he wrote and it's correct. Go home day tomorrow is my story and I'm sticking to it.:cool:
 
Think of Level and Altitude this way. As you climb, you are climbing through altitudes towards levels so you use TA. Descending out of the levels towards altitudes, you use TL. IOW, If you are at a FL, use TL, if you are at an altitude, use TA.
 
In England, TA/TL was both 3000'. Class F airspace also existed over there: uncontrolled airspace above the transition altitude. For some dumb reason, I'm really happy to explain Class F airspace when others can't. What's wrong with me?
