【Multiple selection】With regard to flare, what are the following descriptions correct？（ ）
The rate of decent must be controlled prior to the initiation of the flare(rate not increasing)
Start the flare with positive (or “prompt”) backpressure in the sidestick and holding as necessary
Avoid forward stick movement once Flare initiated (releasing back-pressure is acceptable)
【Single selection】Flight crew should confirm that the lower fuselage structure of tail and APU area is undamaged (tail impact on runway ) when performing exterior walkaround.（ ）
【Single selection】After passing MDH or DH, airplane which can make go around at any altitude should go around decisively, in case of following situations:（ ）
Severe landing bounce deemed by crew
Any crew member calls out “go-around”
ROW warning(if installed)
Other unfavorable landing conditions deemed by crew
All of above
【Multiple selection】Recently, two tail strike incidents happened inside group airlines. For leveling up flight security, and operational quality, Flight crew should （ ）
Flight crew should comply with the requirements of the manual strictly,calculate the correct rotation speed according to the performance ,and make a good rotating speed.Lifting the nosewheel should be in time ,controlling should be gentle before the main gear lift off, avoid sudden pulling the stick due to speed increasing sharply.
Crews should keep risk awareness of tail strike.
Pilots should strengthen the awareness of stabilized approach red line ,keep the attitude and air speed in good condition during landing.
The thrust must be at IDLE prior to touch down. When hard landing or bouncing happens at low altitude,we should freeze the attitude ,idle thrust ,continue landing process. When bounced to high altitude ,we should freeze the attitude ,set TOGA and execute going around.
Do not use rough manoeuvre which may cause an excessive pitching attitude or bank angle while going around ,afterwards lead to a risk of tail striking.
【Multiple selection】Which of the following are the main factors causing tail scrubbing during takeoff. ( )
Early rotation
A fast rotation rate
Configuration
Takeoff trim setting
Crosswind takeoff
Oleo inflation
