Zorluk: ZorNegative Detail Identification

An aircraft pitot-static system measures fluid air pressures to drive critical flight instruments. The pitot tube faces directly into the relative wind to capture total dynamic pressure, while static ports flush-mounted on the fuselage measure ambient atmospheric pressure. The airspeed indicator relies on both inputs, calculating forward velocity by determining the difference between pitot and static pressures. In contrast, the altimeter and vertical speed indicator connect solely to the static system to gauge barometric height and rate of climb. To prevent internal ice blockage at high altitudes, electrical heating elements are integrated into the pitot probe.

Based on the passage, which of the following statements regarding the aircraft pitot-static system is NOT supported by the text?

  1. A
    The airspeed indicator calculates forward velocity by determining the difference between pitot and static pressures.
  2. B
    Static ports are flush-mounted on the fuselage to measure ambient atmospheric pressure.
  3. The vertical speed indicator measures the rate of climb by comparing dynamic pressure to ambient pressure.Cevap
  4. D
    Electrical heating elements are integrated into the pitot probe to prevent internal ice blockage.

Cevap

The statement claiming that the vertical speed indicator measures the rate of climb by comparing dynamic pressure to ambient pressure is not supported by the text.
The passage clearly specifies that the vertical speed indicator connects 'solely to the static system' to gauge the rate of climb. The only instrument that combines and compares dynamic pitot pressure with static pressure is the airspeed indicator. Therefore, the statement asserting that the vertical speed indicator compares dynamic and ambient pressures is contradicted by the text.

Adım Adım Çözüm

1
Identify the negative constraint in the prompt.
The prompt requires finding the single statement that is NOT supported or contradicted by the passage.
Negative detail questions require filtering out all explicitly stated facts to locate the false or unmentioned claim.
2
Cross-examine each option against the factual statements in the stimulus.
The passage confirms that static ports are flush-mounted, the airspeed indicator compares pitot and static pressures, and heating elements prevent ice blockage.
Verifying each true detail eliminates valid distractors that appear in the text.
3
Evaluate the remaining option describing instrument connectivity.
The text states the vertical speed indicator connects 'solely to the static system,' directly contradicting the claim that it compares dynamic and ambient pressures.
Locating the explicit factual contradiction confirms the correct answer to the negative prompt.
