Which of the following is true regarding the use of reduced thrust take-offs? A) If the assumed temperature is lower than the flat rated temperature, then there will be no reduction in thrust. B) It can be used if the OAT is less than the assumed temperature. C) Both A and B are true.
Understand the Problem
The question is asking about the conditions under which reduced thrust take-offs can be applied, specifically focusing on temperature considerations involved in thrust reduction during take-off.
Answer
B) It can be used if the OAT is less than the assumed temperature.
B) It can be used if the OAT is less than the assumed temperature.
Answer for screen readers
B) It can be used if the OAT is less than the assumed temperature.
More Information
Reduced thrust takeoff involves using less than the maximum potential thrust to save engine wear and fuel. Assuming temperature affects the calculation of this thrust, allowing it if the Outside Air Temperature (OAT) is lower than the assumed temperature.
Tips
Be careful not to confuse actual outside temperature with assumed temperature when handling thrust calculations.
