Q

What are the 3 types of Ice Formation and when do they form?

A

CLEAR ICE or GLAZE – produces on the surface if the temperature of
droplets is between 0 and -10 deg. C

RIME ICE – produces on the surface if the temperature of droplets below -10 C

FROST – Builds on the surface of Aircraft that are parked outside in cold nights

Q

What is the difference between the DeIcing and Anti-Icing?

A
  • De-Icing is when there’s an ice
    build up already and then it is removed
  • Anti-Icing is preventing ice build-up in the aircraft systems and
    mainly performed during flight
