Flight Operations and Performance Flashcards
1
Q
FAA Certified Crosswind Limit
A
90º crosswind up to 20% of stall speed
2
Q
Canadian Runway Friction Index (CRFI)
A
- Alternate method for determining crosswind
- Posted in NOTAM’s
- Sometimes not available
3
Q
Contaminated Runway
A
- Standing Water, Slush, snow, frost or ice covering more than 25% of the required length and width of its surface
- May be considered shallow (less than 3 mm water or equivalent) or deep
4
Q
Upslope Runway
A
- Increased Takeoff Distance
- Decreased Landing Distance
5
Q
Downslope Runway
A
- Decreased Takeoff Distance
- Increased Landing Distance
6
Q
Clean Aircraft Concept
A
- Aircraft free of snow, frost, and ice
- Warm hangar is best place to decontaminate
7
Q
Type I Deicing Fluid
A
- Unthicken, applied hot
- Orange in colour
- Good at deicing but not at providing anti-icing
8
Q
Type II Deicing Fluid
A
- Thickened, can be applied hot for deice or cold for anti-ice
- Remains on wing during ground operations and comes off on takeoff roll
- Shouldn’t be used on aircraft with rotation speed less than 100 knots or else fluid won’t come off and will become a contaminant
9
Q
Type III Deicing Fluid
A
- Thickened with properties between type I and II
- Good for aircraft with rotation speeds less than 100 knots
10
Q
Type IV Deicing Fluids
A
- Usually green
- Same specs as Type II but with significantly longer holdover time
11
Q
Cold Soaking
A
- Caused by fuelling aircraft with cold fuel
- Greatly affects wing temp above
- Can cause ice to form and accumulate over time
12
Q
Airframe Icing Effects on Forces
A
- Can reduce lift up to 30%
- Can increase drag up to 40%
13
Q
If Icing is Encountered
A
- Turn 180º
- Land as soon as possible
- No steep attitudes
- Keep moving control surfaces
- Higher airspeed for approach, less flaps
14
Q
Tailplane stall
A
- Nose will drop
- PULL BACK
- Raise Flaps
15
Q
Roll Upset
A
- Ice blocks airflow over ailerons, un-commanded roll
- Lower nose
- Add Power
- Don’t retract flaps
