I need to start a new flight from a presaved flight (because of window settings of an external Fmc), so the "last pos" in Fmc is different from the actual position and often, in a default airport, Airac don't match the position of the gate number or isn't in the database, so I've a problem to align Irs, because I can't use the airport coordinates and the only way is to write down and copy the current coordinates from the FsX map.

 

There's a way to force "last pos" in Fmc to shows the actual coordinates?

 

Thank you

The GPS should show the current coordinates. Can be copied via the scratchpad.

Thank you, it's another way to avoid problem. I hope there's something to solve my question. Thank you again

<p>A few paragraphs gathered from those <em>precision manuals</em> (<span style="color: #0000cd">accentuation </span>is mine). First paragraph is the answer to your question. Third paragraph is still quicker than looking up the FSX map or copying coordinates from double "Shift+Z":<br />
<br />
"IRS Options: The <span style="color: #0000cd">IRS Options sub menu </span>provides you with<br />
some options to customize the way the Inertial Reference<br />
System operates within the simulator. You can choose the<br />
length of time it should take for the IRS to align and <span style="color: #0000cd">whether or<br />
not the IRS will retain the last known memory position of the<br />
airplane</span> at the time it was powered down."<br />
<br />
"The POS INIT page is used during a cold and dark start for<br />
aligning the inertial reference system (IRS) gyros. When loading<br />
from Free Flight as we’ve done in this tutorial, the IRS is already<br />
aligned, so this page doesn’t actually have any real function."<br />
<br />
"Notice the <span style="color: #0000cd">ENTER IRS POSITION </span>message in the scratchpad. We now<br />
need to give the IRSes our current position to align on. There are<br />
several <span style="color: #0000cd">acceptable ways of doing this </span>including using the airport’s<br />
center coordinates from this page, <span style="color: #0000cd">the airplane’s current GPS<br />
coordinates</span> and getting the gate’s coordinates from the airport’s charts<br />
and typing them in manually. In this instance we’ll use the GPS position<br />
as it’s more accurate than using the center of the airport."</p>
