How to - set custom LAT/LON waypoints for navigation?

[richboy2307]

You can create 'custom waypoints' using their LAT/LONG in the DATA menu. Then you may recall these custom waypoints with whatever name (IDENT) you defined for them for use on the F-PLN page.

To define custom waypoints:

• Find the LAT/LON coordinates of the point you want to add onto the MCDU. You'll find this info typically from your OFP. 
   
• On the MCDU press DATA > Next Page > Waypoints (L1 LSK)
  
   
• Here if you have already defined a waypoint before, it will show up its IDENT and let you create a NEW WAYPOINT (R5 LSK).
  If you haven't made any before, then simply give it a name of your choice (E.g. ETOP1) and then enter its LAT/LONG (L2 LSK) in the format DDMM.MB/DDDMM.MB (E.g from above OFP, ETP 1 = 3402.5N/14001.1W)
  
  
   
• To save it click STORE (R6 LSK), note the displayed format will vary slightly from what you've entered
  
   
• Then return to F-PLN page, and insert your desired waypoint where you want it. Note you must use the same IDENT as defined above (e.g. ETOP1)
  
   
• You can add new custom waypoints (upto 20) or delete existing ones from the DATA index page 2, via the STORED WAYPOINTS (R1 LSK) page.
