Zorluk: OrtaNegative Detail Identification

Read the following technical passage about aircraft emergency systems:

A Ram Air Turbine (RAT) is an emergency power source installed on modern military and commercial aircraft. In the event of total engine failure or primary electrical and hydraulic loss, the RAT automatically deploys into the airstream from a compartment in the fuselage or wing. As oncoming airflow spins its multi-blade propeller, the turbine directly drives a dedicated hydraulic pump, an electrical generator, or both. The RAT is governed to operate only when the aircraft maintains a minimum airspeed to ensure sufficient rotational speed. Because it derives its kinetic energy strictly from forward motion, it cannot generate power while the aircraft is stationary on the ground. Once deployed in flight, standard RAT systems cannot be retracted from the cockpit and must be manually reset by ground maintenance personnel after landing.

Match each statement regarding Ram Air Turbine (RAT) operation with its factual status according to the passage.

  • Generating auxiliary power while the aircraft is stationary on the groundContradicted by the passage because power generation requires forward aircraft motion
  • Retracting the deployed turbine assembly mid-flight using cockpit controlsContradicted by the passage because system reset requires ground maintenance personnel after landing
  • Deploying automatically into the airstream upon total loss of primary powerExplicitly confirmed by the passage as the standard operational trigger for deployment

Cevap

Generating power while stationary on the ground matches being contradicted due to forward motion requirements; retracting mid-flight via cockpit controls matches being contradicted due to requiring ground maintenance reset; and deploying automatically upon primary power failure matches being explicitly confirmed by the passage.
The passage outlines clear technical constraints for the Ram Air Turbine. Generating power on the ground is contradicted because the system requires kinetic energy from forward airspeed. In-flight retraction from the cockpit is contradicted because reset requires manual action by ground maintenance personnel. In contrast, automatic deployment following total primary power loss is explicitly confirmed by the text.

Adım Adım Çözüm

1
Evaluate the statement regarding stationary ground power generation against the text.
The passage explicitly notes that the RAT cannot generate power while stationary on the ground because it requires forward motion.
Identifies that ground power generation is a contradicted negative detail.
2
Evaluate the statement regarding cockpit retraction against the text.
The passage confirms that in-flight cockpit retraction is impossible and that reset requires ground maintenance personnel after landing.
Identifies that mid-flight cockpit retraction is contradicted by the passage.
3
Evaluate the statement regarding automatic deployment conditions.
The text directly states that total engine failure or primary electrical/hydraulic loss triggers automatic deployment.
Confirms this statement as a directly stated positive detail.
