B747-4 FMC wind uploads
Greetings,
Any tricks to getting enough room in the FMC to take wind uploads on the legs page on long trips. We had 83 wpts yesterday and kept getting MSG that database was full. Only loaded winds at one FL for only about half the trip. Is there a way to work around this?
TIA

Start by loading the average wind for the whole flight near TOD, then just load winds at the waypoints where significant changes or step climbs occur. A little mental arithmetic may help. Don't forget to load the temperatures as well, that can make a significant difference to the predicted remaining fuel and destination ETA ( more than 20 mins SIN-LHR)
Often I have seen "Route Full" messages when excessive waypoints are required, but never "Database Full"
