vilas,
Is there any tactile speed back for Air speed indicator.
Obviously not. But according to the NTSB report, with more handling practice, the feeling for the need for pitch trim should alert the crew to falling airspeed.
"
More manual flight for Asiana pilots. Asiana’s automation policy emphasized the full use of all automation and did not encourage manual flight during line operations. If the PF had been provided with more opportunity to manually fly the 777 during training, he would most likely have better used pitch trim, recognized that the airspeed was decaying, and taken the appropriate corrective action of adding power."
