Airbus cost index and LRC
Can someone confirm that setting LRC in the A320 /321 requires reference to the LRC tables and manual setting of a specific Mach number that will vary as the weight decreases, rather than setting of a specific Cost Index.
I understand cost index 0 is max range and cost index 999 is min time but we never refer to LRC in our company documents except for some non normal ops.
The 2008 “Getting to grips with Cost Index” doesn’t appear to discuss LRC at all.
Thanks in advance.
