Question 15

where is standby Mag compass and light switch

Answer 15

Standy mag compass above behind FO
Viewing mirrors on the glare shield
light switch lower right hand corner of overhead panel

Question 16

Understand function of the FMS

Answer 16

FMS consists of FMF1 and 2 provided by VIA’s and 2 MCDU’s
pilot uses FCP to select flight modes and the multifunction control display unit to enter flight plans and other flight data flight progress monitored through MCDU
After data entry the FMF’s generate a flight profile from origin to destination airport
