Answer 3

Glycol,, orange, yellow, bright, yellow, green

Question 4

What precautions must be taken for winter Ops?

Answer 4

Oil, type, glycol/deicing fluid, towel covers, dressing for survival

Question 5

Hazards associated with thunders, storms

Answer 5

Turbulence, wind, shear, lightning, icing, precipitation

Question 6

What are critical surfaces?

Answer 6

Everything, but the fuselage

Question 7

What is the clean aircraft concept?

Answer 7

Take off their prohibited when I snore or frost is adhering to any surface

Question 8

What effect the frozen contaminants have on Lift and drag

Answer 8

Reduce by lift by 30% and increasing drag by 40%

Question 9

Effects of frost, ice, or snow on aircraft performance

Answer 9

Decrease thrust or a lift,
Increase in drag and stalling speed
Trim changes
Altered stall characteristics
Poor handling quality

Question 10

Effects of in flight icing

Answer 10

Ice on prop reduces efficiency and increases vibration
Reduced visibility
Impact icing
Jet engine compressor stall.

Question 11

Frozen contaminants removal techniques

Answer 11

Use wing covers
Wait for sun to melt
Store in a heated hangar
De-ice wings using approved chemical

Question 12

Cold soaking

Answer 12

Fuel in wing tanks cools to below freezing
Causes frost to form on upper and under wing when area of precipitation or high humidity is encountered

Question 13

De-icing vs anti-icing

Answer 13

Removal vs prevention

Question 14

What determines which de/anti-icing fluid is used

Answer 14

Rotation speed

Question 15

What are the bases for aircraft de-icing fluid? (Chemical)

Answer 15

Ethylene diethylene or propylene glycol

Question 16

Types and colours of de/anti-icing fluid

Answer 16

I: Orange
II: Yellow
III: Bright Yellow
IV: Green

Question 17

De/anti icing fluid types

Answer 17

Type I: de
Type II, III, IV: anti

Question 18

Factors affecting lift & drag

Answer 18

AoA
Shape of airfoil
Wing area
Velocity squared
Air density

Question 19

Worst conditions for aircraft performance

Answer 19

Hot, high, humid

Question 20

What is ground effect?

Answer 20

Plane flown low to ground/water. Lift is increased and induced drag is decreased.
Occurs Aircraft wingspan height above ground
causes 48% decrease in induced drag

Question 21

What is glide range

Answer 21

Distance of forward travel,divided by the alt lost
Affected by the 4 fundamental forces

Question 22

Effects of tailwind andheadwind on glide range

Answer 22

Tailwind = increased glide distance and hooding = reduced glide dist.

Question 23

Descending at speed less than best glide causes

Answer 23

Increased induced drag.

Question 24

Descending at speed greater than best glide speed causes

Answer 24

Increased parasitic drag

Question 25

What is Flight for max range?

Answer 25

Furthest aircraft can fly per unit of fuel consumed.
Max time of flight for amount of fuel

Question 26

Effects of power on endurance

Answer 26

Reduced time at high power
