А на 86/96 не приходилось пилотировать?
Что там в РЛЭ написано про включение электроимпульсной системы?
Не только на Аэробусах, а и на Боингах и CRJ.
И дело конечко не в тефлоне
Tailplane Icing Incidents
Have occurred on aircraft that have straight fixed tailplanes that use the elevators for both trim and manoeuvre.
Ice on this type of horizontal tail can cause sudden premature flow separation.
Tailplane icing events usually occur on final approach when flaps are extended.
Typically on turboprop aircraft with high energy slipstreams and powerful flap systems.
Separated airflow caused by tail ice can cause a reduction of the pressure recovery over the elevator and result in stick force reversal (control column pulled away from the pilot).
Only applicable to un-powered (manual) elevator flight controls
Tailplanes are designed to be large enough to meet all of the icing certification requirements with ice along the tailplane leading edge (Appendix C icing conditions).
Wind tunnel data shows a progressive loss of tailplane lift (local flow separation) with ice on the leading edges, not a sudden stall.
Stick forces (artificial feel) are not affected by changes to the elevator aerodynamic hinge moments that can be caused by tailplane ice.
The elevator remains effective and the control forces remain linear even with extreme amounts of ice on the tailplane.
