Altimeter settings: QNH versus QFE
I have a question for you CFIG's out the I recently moved to a
"flat" state from a "mountainous" state and noticed that every glider pilot I have met and flown with in the "flat" state sets his altimeter to zero (a QFE setting) instead of field elevation. Back in my old stomping grounds, all my glider friends set field elevation (QNH). I find this a bit disturbing - even dangerous. It's tough to deconflict altitude on the radio when you don't know what the other glider has set his altimeter to! In response to my questions about why this practice of setting the altimeter to zero is so common, invariably the response is "that's the way I was taught" (from both old and new pilots) or that "it's easier for the student to learn that way" from instructors. Does this mean that flatland student pilots are mathematically challenged, while those in mountainous areas are not? I also hear "it's easier to tell how high up I am when landing". Huh? What happened to no-altimeter/TLAR patterns? Or are people being taught rigid altitudes in the pattern? So - what gives? Is this technique commonly taught? Do instructors really believe it helps their student? Is it even legal (how do you get a current altimeter setting during a long flight)? No prize for figuring out my opinion about this practice... And please, no tangential discussion about using QFE for IMC approaches - unless you have two altimeters in your glider... Kirk 66 |
