Airframe Icing Flashcards
What should wise pilots do regarding icing conditions?
Wise pilots put every effort into staying out of the ice or fleeing if ice is encountered.
What is the technique for dealing with ice?
The technique is to take action at the first sign of ice.
What can happen if you continue into icing conditions?
Continuing into icing conditions, hoping for improvement, can definitely be hazardous to your health.
What causes icing?
Icing occurs when super cooled water droplets are splattered by the airplane and then freeze.
What is a super cooled water droplet?
A super cooled water droplet is one that has been lifted from an above freezing temperature to a below freezing temperature.
Where is the most severe icing likely to be encountered?
The most severe icing will likely be encountered where there is moisture and where there is lifting.
What is the relationship between turbulence and ice severity?
If the air is turbulent and ice is encountered, there will likely be a lot of ice.
Can ice be present in smooth stratus clouds?
Yes, ice can be present in smooth stratus clouds, and accumulations could still be substantial.
How is ice classified?
Ice is classified as clear, rime, or mixed.
Where is clear ice likely found?
Clear ice is more likely found in cumulus clouds, very unstable air, or with strong mechanical lifting over mountains.
What is rime ice?
Rime ice is milky looking and is created by much smaller super cooled water droplets as might be found in stratus clouds.
What is mixed ice?
Mixed ice is a combination of clear and rime ice.
What should you be alert for when flying in visible moisture at low temperatures?
Be alert for the formation of ice.
What type of precipitation creates airframe ice quickly?
Freezing rain creates airframe ice and can coat an airplane quickly.
