SIFT Reading Comprehension Questions and Answers 2 — Questions and Answers
Question 1: A passage states: 'The Army requires aviators to maintain instrument currency by logging at least six instrument approaches within six months.' What does 'instrument currency' mean in this context?
- Having a current, valid instrument rating certificate
- Maintaining recent practice and proficiency in instrument flight to legally exercise instrument privileges (Correct answer)
- Paying the fees associated with instrument flight training
- Having the most recent version of instrument approach charts
Correct answer: Maintaining recent practice and proficiency in instrument flight to legally exercise instrument privileges
'Currency' in aviation means being currently qualified through recent practice, not just holding a certificate. Instrument currency specifically requires recent logged approaches and other tasks.
The passage defines instrument currency through the example of approach requirements. It means the pilot is not just certified but recently practiced and legally authorized to fly in instrument conditions. The term 'currency' (like current money) implies being valid and up-to-date, which in aviation requires ongoing practice.
Question 2: Read: 'Spatial disorientation accounts for approximately 15% of all fatal general aviation accidents. Unlike visual illusions, many spatial disorientation incidents occur in actual IMC when pilots have no outside visual reference.' What is the main conclusion?
- Most pilots do not know how to fly in IMC
- Spatial disorientation is a significant and disproportionately fatal hazard, especially in IMC (Correct answer)
- Instrument training eliminates all risk of spatial disorientation
- General aviation is more dangerous than commercial aviation
Correct answer: Spatial disorientation is a significant and disproportionately fatal hazard, especially in IMC
The passage emphasizes that spatial disorientation accounts for 15% of fatal accidents, highlighting it as a serious risk, particularly when outside visual references are unavailable.
The main conclusion is drawn from two facts: the high percentage of fatal accidents and the specific context of IMC. The passage does not say most pilots lack IMC skills or that training eliminates the risk — it simply establishes that spatial disorientation is deadly and more common when visual references are absent.
Question 3: A manual states: 'Pre-flight inspection is mandatory before every flight, regardless of the time elapsed since the last inspection or the number of flight hours since the previous pre-flight.' What does 'regardless' signal?
- The rule applies only in certain conditions
- The rule has exceptions for experienced pilots
- The rule applies universally with no exceptions (Correct answer)
- The rule is a guideline, not a requirement
Correct answer: The rule applies universally with no exceptions
'Regardless' indicates that no conditions or circumstances create exceptions to the rule — pre-flight is required every single time.
The word 'regardless' is an absolute qualifier that eliminates exceptions. Whether the aircraft was inspected 5 minutes ago or 5 days ago, and whether it flew recently or not, the pre-flight is still required. This reflects aviation safety philosophy: never assume — always verify.
Question 4: Passage: 'The Chinook's tandem rotor design eliminates the need for a tail rotor. This allows all engine power to be directed to lift and forward flight rather than anti-torque. As a result, the Chinook is more efficient per horsepower than comparable single-rotor helicopters.' What is the key advantage described?
- The Chinook can fly faster than any other helicopter
- Eliminating the tail rotor frees all power for productive lift, improving efficiency (Correct answer)
- The tandem rotor design is easier to maintain
- The Chinook requires less pilot training due to its design
Correct answer: Eliminating the tail rotor frees all power for productive lift, improving efficiency
The passage explains a direct cause-and-effect: no tail rotor → all power goes to lift → better efficiency per horsepower. That is the key advantage.
The passage presents a three-step argument: (1) no tail rotor needed, (2) therefore all power goes to useful work, (3) therefore better efficiency. The other options are not mentioned in the passage. Good reading comprehension requires identifying what the passage actually argues, not importing outside knowledge.
Question 5: A regulation states: 'Pilots shall not begin a flight unless the aircraft has sufficient fuel to fly to the first intended landing and, assuming normal cruise conditions, fly at least 20 minutes more.' What is the minimum fuel requirement?
- Enough to reach the destination only
- Fuel to reach the destination plus a 20-minute reserve (Correct answer)
- At least 1 hour of total fuel
- 20 minutes of fuel total
Correct answer: Fuel to reach the destination plus a 20-minute reserve
The regulation requires fuel for the trip to the first landing point PLUS an additional 20-minute reserve — not just enough to arrive.
The conjunction 'and' creates two requirements: (1) fuel to reach the first landing, and (2) an additional 20 minutes. Together they define the minimum. The '20 minutes more' is explicitly a reserve beyond the trip fuel. This type of precise reading is tested on the SIFT.
Question 6: Read: 'Night vision goggles enhance the aviator's ability to detect terrain and obstacles in darkness, but they significantly narrow the field of view and eliminate depth perception at long range.' What limitation is described?
- NVGs cause complete blindness in daylight
- NVGs improve everything about night vision equally
- NVGs improve detection but restrict field of view and reduce depth perception (Correct answer)
- NVGs only work in total darkness
Correct answer: NVGs improve detection but restrict field of view and reduce depth perception
The passage uses 'but' to introduce limitations: narrowed field of view and eliminated depth perception at long range — clear trade-offs for the improved detection ability.
The passage presents a balanced statement: NVGs help (detect terrain and obstacles) but also limit (narrow FOV, no depth perception at range). The correct answer must capture both parts of this contrast. Answers that ignore the 'but' clause or exaggerate beyond what's stated are incorrect in reading comprehension questions.
