To add,
There are two Navigraph means of producing flight plans which are quite separate: Navigraph Charts and SimBrief.
The INIT REQ procedure you mention is for SimBrief plans.
If you have created/edited a flightplan in Charts, and prefer the immediate INIT REQ procedure, you could:
- Copy the route from the Charts Type route facility.
- Paste into a SimBrief plan
- Generate OFP again for entry into MCDU.
- Load into MCDU using INIT REQ
- For details, please see How to combine two flight plans ( SimBrief & Navigraph ) - #2 by Ian
Cheers
