Zorluk: OrtaDrawing Logical Conclusions

Read the passage below. Based on the technical details provided, complete the sentence with the most logical conclusion regarding the system that malfunctioned.

Cevap:Aviation maintenance protocols state that aircraft pitot tubes must be electrically heated during sub-zero flights to prevent atmospheric ice from blocking the forward intake. When an intake becomes obstructed with ice, dynamic ram air cannot enter the sensor, causing the cockpit airspeed indicator to drop to zero while the static line and altimeter continue functioning normally. During a routine winter patrol, an aircraft operating with steady engine thrust experienced an abrupt drop in its airspeed reading to zero, while altitude readings remained completely accurate. Based strictly on the provided text, the maintenance crew can deduce that a failure occurred in the 【pitot heat】 system.

Cevap

pitot heat (or pitot heating / pitot tube heating)
The passage explains that sub-zero flights require electrical pitot tube heating to prevent ice from blocking the intake. When ice blocks the intake, dynamic ram air is cut off, causing airspeed readings to fall to zero while the altimeter continues to read accurately. Because the aircraft experienced an airspeed drop to zero in freezing conditions while maintaining thrust and accurate altitude, the maintenance crew can logically conclude that the electrical pitot heating mechanism failed to prevent ice accumulation.

Adım Adım Çözüm

1
Identify the symptoms described in the flight scenario.
The flight was conducted in sub-zero winter weather, engine thrust remained steady, altitude readings were normal, but the airspeed indicator dropped to zero.
Connecting specific reported symptoms to explicit system behaviors outlined in the text is necessary to isolate the underlying cause.
2
Match the observed symptoms to the causal mechanisms provided in the passage.
The passage explicitly notes that an ice obstruction in the pitot intake makes the airspeed gauge read zero while the static altimeter remains normal.
Synthesizing the exact conditions distinguishes an intake blockage from an engine or static system failure.
3
Deduce which preventive system failed to allow the blockage under sub-zero conditions.
Because electrical pitot tube heating is required in sub-zero conditions to prevent ice formation, a failure of the pitot heating system is the direct cause of the icing and subsequent gauge failure.
Drawing a logical conclusion requires identifying the primary failed safeguard that permitted the chain of events to occur.
