What is the function of freeze on MCDU in A320
thx!freeze the irs position for?
|
You can use it to plot your position as a gross error check on oceanic routes.
|
Is that mean if I press the freeze*,the MCDU will create a fix that use as a VOR?
|
It just means that when you press freeze, a snapshot of the current LAT/LONG is taken.
You can then use this position to make a plot on a chart. |
Thank you for reply.
I can only find the info on FCOM said that If there is a discrepancy between the raw data position and the FM position: PRESS the DATA key on the MCDU. SELECT the POSITION MONITOR page. SELECT “FREEZE”. On the other MCDU: Select the GPS MONITOR page. But when you found the discrepancy situation then press the freeze*. Is that will get the wrong positon? |
