LOE Considerations Flashcards
Windshear Considerations/Limitations on Takeoff
- No Flex
- Use longest runway available
- Flaps 8 TO recommended
- DO NOT engage Autopilot below 1,500’
Windshear Considerations/ Limitations for Approach and Landing
- Avoid large thrust reductions or trim changes
- Use Autopilot on approach
Operating on Contaminated Surfaces
- Taxi with both engines
- Use manageable speed (10-20 knots max)
- Maintain greater distance to other aircraft
- Minimum use of brakes
- 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
Takeoff on Contaminated Runways
- NO FLEX
- Continuous Ignition on
- Light forward pressure on control wheel may increase directional control
Rejected Takeoff on Contaminated Runway
- Anticipate skidding
- If skidding occurs reduce reverse thrust to idle, or forward thrust if needed, and regain directional control with steering
- Directional control problems can be caused by anti-skid, reduce brake pressure to help regain control
Landing on Contaminated Runway
- Lower the nose immediately and use light forward pressure
- DO NOT PUMP THE BRAKES
- Anticipate skidding
Takeoff and Landing: What constitutes a Contaminated Runway
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)
When is Continuous Ignition required
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
Reduced Thrust Takeoff Limitations
- PROHIBITED if Anti-skid is inoperative
- PROHIBITED on contaminated runways
- PROHIBITED if the airplane has been de-iced
- PROHIBITED if wing and/or cowl anti-icing bleeds are in use
- PROHIBITED if warnings of windshear or downdrafts have been forecast
- PROHIBITED with an engine that cannot achieve full-rated thrust
- PROHIBITED when a special departure procedure specifies full thrust for takeoff
Steps to do when Cleared to Hold
- Turn to correct heading
- Bug the Alt and start down
- Slow to holding speed
- Build the holding pattern
