CARS ICING
Here's what you should know:
• ensure carb heat works during pre-takeoff check.
• repeatedly monitor engine instruments for loss of rpm (fix
pitch) or manifold pressure (constant speed) - this means ice
is forming.
• select full carb heat early - and keep it on (the engine may
run rough while the ice melts).
• move mixture control carefully, leaning to smooth engine
roughness as the ice melts.
• be aware that carb or induction ice can form while climbing
- and apply carb heat pnor to levelling off if icing is
suspected.
• prior to descent, apply full carb heat - periodically open
throttle during extended closed-throttle descent for added heat
to melt ice.
Refer to chart showing temperature / dewpoint ranges of
carb icing.
• MOGAS warning: Due to its higher volatility, MOGAS IS more
susceptible to the formation of carb icing. :n severe cases, ice may
form at OATs up to 20 degrees C higher than with AVGAS.
