Ppl Flashcards
(26 cards)
What are pilot in command responsibility?
Aircraft airworthiness flight, planning passenger briefing, aircraft separation, compliance with regulations and instruction
I’m safe?
Illness, medication, stress, alcohol, fatigue, eating
Deicing fluid contains XX and has XX colours
Glycol,, orange, yellow, bright, yellow, green
What precautions must be taken for winter Ops?
Oil, type, glycol/deicing fluid, towel covers, dressing for survival
Hazards associated with thunders, storms
Turbulence, wind, shear, lightning, icing, precipitation
What are critical surfaces?
Everything, but the fuselage
What is the clean aircraft concept?
Take off their prohibited when I snore or frost is adhering to any surface
What effect the frozen contaminants have on Lift and drag
Reduce by lift by 30% and increasing drag by 40%
Effects of frost, ice, or snow on aircraft performance
Decrease thrust or a lift,
Increase in drag and stalling speed
Trim changes
Altered stall characteristics
Poor handling quality
Effects of in flight icing
Ice on prop reduces efficiency and increases vibration
Reduced visibility
Impact icing
Jet engine compressor stall.
Frozen contaminants removal techniques
Use wing covers
Wait for sun to melt
Store in a heated hangar
De-ice wings using approved chemical
Cold soaking
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
De-icing vs anti-icing
Removal vs prevention
What determines which de/anti-icing fluid is used
Rotation speed
What are the bases for aircraft de-icing fluid? (Chemical)
Ethylene diethylene or propylene glycol
Types and colours of de/anti-icing fluid
I: Orange
II: Yellow
III: Bright Yellow
IV: Green
De/anti icing fluid types
Type I: de
Type II, III, IV: anti
Factors affecting lift & drag
AoA
Shape of airfoil
Wing area
Velocity squared
Air density
Worst conditions for aircraft performance
Hot, high, humid
What is ground effect?
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
What is glide range
Distance of forward travel,divided by the alt lost
Affected by the 4 fundamental forces
Effects of tailwind andheadwind on glide range
Tailwind = increased glide distance and hooding = reduced glide dist.
Descending at speed less than best glide causes
Increased induced drag.
Descending at speed greater than best glide speed causes
Increased parasitic drag
