    protection of the blades
  • Enhanced take-off distance by approx. 5 %
    (MTOW, SL, ISA conditions)
  • Enhanced climb performance by approx. 5 %
    (MTOW, SL, ISA conditions)
  • Enhanced cruise performance by 2 to 3 kts
    (MTOW, ISA conditions)
  • Cooler ITTs during engine start up, therefore
    less engine wear and reduced risk of hot start!
  • Significant inside and outside noise reductions
  • Unlimited blade life; FOD repairable blades
