ER- yeah.
UNLESS you are on an LNAV track and can use VNAV PTH, what OTHER mode would you use to achieve a CDA?
Well, technically you could use FLCH and wait for the A/T HOLD mode then position the levers manually as per FCTM... but this gets funny looks from the F/O as you tweak back and forth to maintain the desired path/R.O.D...
