Systems: Deicing and Anti-Icing Quiz

Question 1 of 10

1. Question

What is the main difference between anti-ice and de-ice systems?

Anti-ice prevents ice from forming, while de-ice removes existing ice
Anti-ice removes ice after it forms, while de-ice prevents it
Anti-ice is used in warm weather, while de-ice is for freezing temperatures

How do pneumatic boots remove ice?

They inflate and contract to crack and shed ice
They use bleed air to maintain a warm leading edge
They heat the surface to melt ice before it forms

What is a key operational consideration when using pneumatic de-icing boots?

They should only be activated after ice has built up
They require continuous operation at all times
They should be turned on before entering known icing conditions

1 point(s)

How does a weeping wing system (TKS) work?

It pumps anti-icing fluid through porous panels or laser-drilled holes
It redirects exhaust heat to melt ice
It sprays fluid onto ice prone surfaces

What is the main limitation of anti-icing and de-icing systems?

They may be ineffective in severe icing conditions
They only work at temperatures above freezing
They eliminate the need for pilots to monitor ice accumulation

9. Question

1 point(s)

What should a pilot do if an anti-icing system fails in flight?

Descend or change course to exit icing conditions as soon as possible
Continue flying normally and rely on de-icing boots
Use cabin heating to warm the wings

10. Question

1 point(s)

When should the heated pitot tube be turned on?

Before entering known icing conditions
When the pitot-static system stops functioning
Only after ice has formed on the pitot tube
