#4 Flashcards
Types of AIRMET
Tango, Zulu, Sierra
AIRMET Tango
Moderate turbulence, less then 30 kts, low level wind sheer
AIRMET Zulu
Moderate icing and provides freezing levels
AIRMET Sierra
Describes IFR conditions or mountain obstructions
Frost Effects
Frost alters the aerodynamic characteristics of the wing sufficiently to interfere with take-off by increasing stall speed and reducing lift.
Icing Effects
Increased Drag, Increased Weight, decreased thrust, decreased lift
FAA rule taking off with debris on the wings
Completely clear wing before taking off
Avoiding Icing Hazards
Avoid flight into an area where icing conditions are known to exist. Do not fly through rain showers or wet snow when the temperature is near 0°C. Do not fly into cumulus clouds when the temperature is low.
