fail close or open with loss of DC?

Definition

 

 

 

 

 

Fails closed

Term

 

 

 

Why does the AFM ask to heat the brakes

within the last mile of taxi in

cold weather and contaminated taxiway?

Definition

Short answer:

To remove excess water

 

Longer answer:

Carbon brakes are "hygroscopic",

meaning it absorbs liquids.

 

Once the still wet wheel assemblies get colder temperature, the liquids spread further apart between the rotors and stators and lock the brakes solidly.

Term

Definition

 

 

 

 

Accumulation standing more than 12 to 18 inches aft of heated leading edge.
