LOE Considerations

Question 1

Windshear Considerations/Limitations on Takeoff

Answer 1

1. No Flex
2. Use longest runway available
3. Flaps 8 TO recommended
4. DO NOT engage Autopilot below 1,500’

Question 2

Windshear Considerations/ Limitations for Approach and Landing

Answer 2

1. Avoid large thrust reductions or trim changes
2. Use Autopilot on approach

Question 3

Operating on Contaminated Surfaces

Answer 3

1. Taxi with both engines
2. Use manageable speed (10-20 knots max)
3. Maintain greater distance to other aircraft
4. Minimum use of brakes
5. When moderate to severe icing during prolonged ground operations, periodic runups (54%-70% N1) are recommended. Min 15 seconds at 10 minute intervals and within 5 minutes of takeoff

Question 4

Takeoff on Contaminated Runways

Answer 4

1. NO FLEX
2. Continuous Ignition on
3. Light forward pressure on control wheel may increase directional control

Question 5

Rejected Takeoff on Contaminated Runway

Answer 5

1. Anticipate skidding
2. If skidding occurs reduce reverse thrust to idle, or forward thrust if needed, and regain directional control with steering
3. Directional control problems can be caused by anti-skid, reduce brake pressure to help regain control

Question 6

Landing on Contaminated Runway

Answer 6

1. Lower the nose immediately and use light forward pressure
2. DO NOT PUMP THE BRAKES
3. Anticipate skidding

Question 7

Takeoff and Landing: What constitutes a Contaminated Runway

Answer 7

Contaminant…………………Takeoff / Landing
Standing Water…….½ in (12 mm) / ¾ in (19 mm)
Slush……………….9/16 in (14 mm) / 7/8 in (22 mm)
Wet Snow……….9/16 in (14 mm) / 7/8 in (22 mm)
Dry Snow…………….3 in (76 mm) / 3 ¾ in (95 mm)

Question 8

When is Continuous Ignition required

Answer 8

Continuous engine ignition must be used during the following:
* Takeoff and landing on contaminated runways
* Takeoff with high crosswind components (15 knots or greater)
* Flight through moderate or heavier intensity rain
* Flight through moderate or heavier intensity turbulence
* Flight in the vicinity of thunderstorms

Question 9

Reduced Thrust Takeoff Limitations

Answer 9

1. PROHIBITED if Anti-skid is inoperative
2. PROHIBITED on contaminated runways
3. PROHIBITED if the airplane has been de-iced
4. PROHIBITED if wing and/or cowl anti-icing bleeds are in use
5. PROHIBITED if warnings of windshear or downdrafts have been forecast
6. PROHIBITED with an engine that cannot achieve full-rated thrust
7. PROHIBITED when a special departure procedure specifies full thrust for takeoff

Question 10

Steps to do when Cleared to Hold

Answer 10

1. Turn to correct heading
2. Bug the Alt and start down
3. Slow to holding speed
4. Build the holding pattern
