ALT HOLD & climbing in VNAV
...in a Boeing that is.
If climbing with VNAV engaged, to say FL300, and with MCP ALT set to 30000 for instance, engaging ALT HOLD on the MCP would cause the auto pilot to command a level off at an altitude marginally higher (say 28000 if the hold was pressed at 27500 and according to rate of climb) than when the mode was selected and according to a 'smooth' transition from climbing attitude to level flight... Am I right or wrong?
Nish.
