What to do in these situations?
Rpm LOW - manifold LOW
Rpm LOW - manifold HIGH
Rpm HIGH - manifold LOW
Rpm HIGH manifold HIGH
Rpm LOW- man LOW
Increasing the throttle increases manifold pressure and rpm
Rpm LOW - man HIGH
Lowering the collective pitch decreases manifold pressure and increases rpm
Rpm HIGH - man LOW
Raising the collective pitch increases manifold pressure and decreases rpm
Rpm HIGH - man HIGH
Reducing the throttle decreases manifold pressure and rpm
Takeoff is prohibited when ____ , ___ , or ____ is adhering to any critical surface of the aircraft.

What is cold soaking?
When an aircraft travels from warm location to cold one, then back to warm, condensation and one may build up on skin

When should a pilot be extra cautious regarding the possibility of cold soaked fuel tanks?
After descending from cruise altitude
What are the three main types of aircraft icing?
Clear, mixed, rime
How does airframe ice form?
Super-cooled water droplets strike a cold airframe.
In what temperature range is the risk of airframe icing most severe in convective cloud?
0 to -10 c
In what cloud type is the risk of severe clear airframe icing present?
Cumulus, 0 to -10 c
Clear ice is formed in:
Freezing rain
Rime ice is formed in:
Stratiform clouds
Which type of icing would anti-icing/de-icing equipment be more effective on?
A.Clear
B.Mixed
C.Rime
D.Snow
C
Large super-cooled water droplets Require strong vertical currents to support them, therefore they are most commonly found in cumulus cloud.
True or false
True
Clear ice is formed in:
Cumulus clouds
The most serious icing is found in:
Cumulus cloud
Describe rime ice?
- formed by instantaneous freezing of supercooled water droplets (skin temp less than 0)
- rough, milky opaque like the inside of a freezer
- forms in layer clouds like stratus
- not very adhesive, brittle
- results in light to moderate icing
Describe clear ice?
• Formed when large supercooled water drops slowly freeze to the aircraft (skin temperature less than 0°C).
• Smooth and transparent.
• The most dangerous type of icing.
• Especially just below freezing with large supercooled water droplets.
• Larger accumulations are characterized by the presence of upper and lower “horns.”
Describe mixed icing?
A mixture of clear and rime ice
What are three factors that have an effect on the rate of ice accumulation?
- Airfoil shape
- airfoil speed
- droplet size
