[单选题]When using DES to descent, if the aircraft is below the descent profile, how to assume the interception point on the navigation display?
A. If the aircraft is flying at an altitude that is higher than both the descent speed limit altitude and the destination elevation +5000 ft: the FMGS maintains the V/S at -1000 ft/min and the target speed, until the aircraft reaches the altitude constraint, or intercepts the descent profile
B. If the aircraft is flying at an altitude that is lower than either the descent speed limit altitude or the destination elevation +5000 ft: the FMGS maintains the V/S at -500 ft/min and the target speed, until the aircraft reaches the altitude constraints, or intercepts the descent profile
C. Both A and B are correct

B. M 0.80 or 350KT
C. M 0.82 or 350KT
[单选题]In case of an excessive descent rate, which aural warning will be triggered?
A. SINK RATE
B. TERRAIN TERRAIN
C. GLIDE SLOPE

A. A. 30-1000ft
B. B. below 1500ft
C. C. From capture ILS to 50ft
[单选题]When using DES to descent, if it is higher than FMGS glide path, the navigation display presents a pseudo waypoint (interception point) along the flight plan that assumes the aircraft will return to the profile using:
A. Idle thrust and 1/2 speedbrake extension
B. ECON speed plus a margin (until intercepting the profile)
C. Both A and B are correct
[单选题]During approach, flight augmentation computer calculates the speed tendency and the minimum selectable speed (VLS). The tendency limit or VLS indicates the speed the aircraft will reach in the future 10 seconds and _____ times of VS1g under any configuration.
A.1.13
B.1.23
C.1.33
[单选题]DES provides managed vertical guidance along the descent path. Which of the following statement is correct?
A. The system computes the profile backwards from the “deceleration point” up to the “top of descent”, with respect to the speed and altitude constraints at the deceleration point, the guidance begins the deceleration to VAPP, to be reached at 1000 ft above touchdown on the final descent path.
B. If the aircraft is above the descent profile, the speed will increase toward the upper limit of the managed speed range. If the speed reaches the upper limit, the aircraft will maintain the speed but will deviate from the profile (autothrust at idle)
C. Both A and B are correct
[单选题]The establishment of flight plan uses:
A. information from navigation database
B. information from performance database
C. information from navigation database and performance database
[单选题]The vertical waypoint of the vertical flight path refers to :
A. the point in navigation database with fixed geographic position
B. the point imposed by ATC
C. the point without fixed geographic position but affected by atmospheric point
