[QUOTE="jmden, post: 207112, member: 1742"] Eaglet, I'm confused. Try doing what you are saying either in 'field conditions' or in 'save sight in information' and when you enter the new altitude and hit update, you will see the program check the 'calculate standard pressure' and see the pressure value changed to a predicted pressure just as the screen changes. The program then makes a predicted trajectory based on the predicted standard pressure for that altitude, which could be somewhat off depending on if there is a hi or lo pressure system in the area. You need to measure station pressure at your new location. That's what's important, not altitude. You can put whatever altitude you want in 'field conditions' and the predicted trajectory will not change if 'calculate standard pressure' stays unchecked because the pressure remains constant this way unless you manually change it. However, everytime you go to change altitude, you have to watch very closely as the program will check 'calculate standard pressure' and enter in that calculated pressure (just a number from a table, perhaps quite a bit differnent than actual station pressure) just as you hit update. Are we communicating, or am I just muddying the waters? :) [/QUOTE]
