Difficulty: MediumQuantitative Detail Extraction

During pre-flight inspections of the CRU-60/A oxygen regulator and auxiliary emergency supply on tactical aircraft, life support technicians must verify specific pressure thresholds. The main liquid oxygen converter delivers gaseous oxygen to the pilot at a regulated pressure of 70 psi during standard cruising altitudes. However, the seat-mounted emergency bailout cylinder is charged to a much higher pressure of 1,800 psi. If cabin depressurization occurs above 30,000 feet, the emergency system automatically deploys, providing approximately 10 minutes of breathable oxygen while the pilot descends to a safe altitude of 10,000 feet.

According to the passage, what is the charged pressure of the seat-mounted emergency bailout cylinder?

  1. A
    70 psi
  2. B
    10,000 psi
  3. 1,800 psiAnswer
  4. D
    30,000 psi

Answer

1,800 psi
The passage explicitly states that the seat-mounted emergency bailout cylinder is charged to a pressure of 1,800 psi.

Step-by-Step Solution

1
Locate the sentence in the passage that explicitly describes the seat-mounted emergency bailout cylinder.
The text states: 'However, the seat-mounted emergency bailout cylinder is charged to a much higher pressure of 1,800 psi.'
Direct extraction requires targeting the exact component identified in the prompt.
2
Isolate the numerical value associated with the emergency cylinder from the other figures in the passage.
Identify 1,800 psi as the cylinder charge, distinguishing it from 70 psi (main converter delivery), 30,000 feet (activation altitude), and 10,000 feet (descent altitude).
Multiple quantitative details appear in the passage, requiring differentiation between pressures and flight altitudes.
