Altimeter Calibration Height

news Steven P. McNicoll wrote: "Matt Whiting" wrote in message ... Yes, great idea. I thought so. Take an altimeter and set it on a table. Don't move it! Turn the knob that adjusts the pressure scale to one extreme. Record the indication on the face of the altimeter. Now turn the knob to the other extreme of travel. Record the indication on the face of the instrument. Now the big question: which value recorded is the altitude at the level of the instrument? One step at a time. Let's see where you are in your understanding of altimetry before we move on. Answer the questions I posed to Neil Gould. Yes, one step at a time. Tell me how an instrument that indicates its own altitude can indicate two vastly different values without changing its altitude? It is a very simple question. Which altitude changed? Indicated altitude? Pressure altitude? Density altitude? True altitude? (Does one presumes WGS84 when speaking of true altitude?) |

It is a very simple question. Let's answer the questions in the order they were asked. Ok, I understand that you don't have an answer. |

Considering the definitive answer to the original question provided by Kev, and the fact that the presented information agrees with my understanding and usage of the terms, I think it puts the question to rest. I'm glad you're content. |
