A320 questions
Could someone answer to these questions about A320 ? Il would greatly help me.
1/ How works fcu speed/mach, heading/track, and altitude knobs : Have they three positions : Selected (pulled) Managed (pushed) and the inactive position(disengage selected or managed mode). Or are they only used to engage a selected or managed mode. In this case, how disengage them ?
2/ What exactly is Vls ? when is it represents 1.13 Vs or 1.23 Vs ? is it depends on load factor like Vs, Alpha protection and alpha max spd ?
3/ About the Engine rating limit control : FLEX power can be used for takeoff if a FLX temperature has been entered via the MCDU. When Flex power becomes inactive ? Is it replaced by maximum continuous thrust ?
4/ Finally, what is the conditions needed for a LOC and GS capture ?
All explanations would be appreciated !
