Set delays between annoucement

[nbl2508]

Thanks for your answers, but i already use the real time load. But it is not really what I ask.

When aircraft is loaded (2 min or 20min) depending on what I ask, it triggers the whole crew annoucement. What I want is that theses
annoucment are delayed after aircraft is loaded :
- of for immediately warn that aircraft is loaded and ready to go.
- but for slides arming, it should be a few second after the parking breaks are released.
- and saftety procedure should be a few time before starting the taxi.

I'd like to choose every delays between these annoucement, and they should be triggered by event like park break released, or aircraft
begining to taxi.
