Intersection of 2 radials with VORs Out of Service

How would you use the Garmin 430/530 to determine the intersection of the MGW 336 radial and the CKB 039 radial? (Answer in next post.) ____________________ Richard Kaplan, CFII rkaplan@flyimc.com http://www.flyimc.com rkaplan Administrator Joined:  Sun Jan 22nd, 2006 Location:  Uniontown, Pennsylvania USA Posts:  387 Status:  Offline  Posted: Wed Mar 1st, 2006 09:21 pm Quote Reply rkaplan wrote: How would you use the Garmin 430/530 to determine the intersection of the MGW 336 radial and the CKB 039 radial?   Go to the User Waypoint page.  An easy way to enter this page is to enter an unused waypoint identifier into your flight plan.   The most common way to define a user waypoint is by entering a bearing and distance from the waypoint.  However, you can also define a user waypoint as shown below as the intersection of two radials.    (Note that in this example the distance 5.2nm is calculated automatically by the GPS after the user enters the two defining VORs and radials.)     Attachment: 2rads.jpg (Downloaded 56 times) ____________________ Richard Kaplan, CFII rkaplan@flyimc.com http://www.flyimc.com JimP Member   Joined:  Wed Apr 5th, 2006 Location:  Portland, Oregon Posts:  23 Status:  Offline  Posted: Fri Apr 21st, 2006 01:32 pm Quote Reply In trying this on the simulator... it seems that the 2nd VOR/Radial is used to define the user waypoint successfully, but if you recall the user waypoint, then the 2nd VOR/Radial information may actually reference a different VOR.  From what I can tell, the waypoint is stored correctly (ie: Lat/long), but the 2nd VOR identifier and radial are not retained.   It seems that maybe the closest VOR (not sure about this) is referenced on line 2 instead. /Jim ____________________ Visit my family web page at http://www.pappasfam.com rkaplan Administrator Joined:  Sun Jan 22nd, 2006 Location:  Uniontown, Pennsylvania USA Posts:  387 Status:  Offline  Posted: Fri Apr 21st, 2006 01:51 pm Quote Reply JimP wrote: From what I can tell, the waypoint is stored correctly (ie: Lat/long), but the 2nd VOR identifier and radial are not retained.   It seems that maybe the closest VOR (not sure about this) is referenced on line 2 instead. Yes that is exactly correct.   ____________________ Richard Kaplan, CFII rkaplan@flyimc.com http://www.flyimc.com  Current time is 06:20 am
