What do the different types of approach abbreviations used on the A320 MCDU exactly mean? On the MCDU I have noticed after setting up the approach there are a number of different codes which appear next to the runway designator these are namely as below:
CI
CF
FI
CD
FD
Can someone kindly explain what these codes mean.
CI = course to intercept
CF = course to fix
FI = fix to intercept
CD = course to DME
FD = fix to DME
These are AIRINC 424 leg types. You can find more information on them here
