EOSIDs are created with a set of parameters which include minimum and maximum bank angels.
Though they can be coded in database, no NAV or LNAV is able to use the bank angles required as they are variable depending on configuration and manoeuvre capability.
Reason why these are NOT to be flown in managed guidance is to ensure the parameters are not exceeded for phase of flight.
If a procedure bank angle requires 20 or less for obstacle clearance turn radius, while NAV can manage 25 due configuration, it will fly 25, possibly then encroaching an area avoided by calculations of obstacle clearance.
For straight out segments and turns after initial limitations are overcome, managed guidance works a treat!
Managed guidance is not always a better option, but does aid the pilots in a visual representation at all times.
