Most accidents take place during
- ACruise.
- BApproach and Landing.
- CTake off and initial climb.
Why that is the answer
The approach and landing phase of flight accounts for a disproportionately large share of aviation accidents relative to the small fraction of total flight time it occupies — a pattern well documented by the Flight Safety Foundation's Approach and Landing Accident Reduction (ALAR) task force and reflected throughout ICAO human-factors material. During approach and landing the crew is simultaneously managing a high workload — configuring the aircraft, following a descent profile, monitoring speed and energy state, communicating with ATC, and preparing for a go-around if needed — often in demanding conditions such as poor visibility, crosswinds, or an unstabilised approach, all in close proximity to terrain and obstacles where there is very little margin to recover from an error. This combination of high workload, low altitude, and reduced time to correct a developing problem is why this phase, despite representing only a small percentage of total flight duration, is statistically the leading phase for accidents. Cruise, by contrast, is the lowest-workload, highest-altitude phase with the most time available to detect and correct any developing problem, and take-off/initial climb — while also elevated in risk — has historically accounted for a smaller share of accidents than the approach-and-landing phase as a whole.
- Approach and landing combine high crew workload, close proximity to terrain, and very little time margin to recover from an error.
- The Flight Safety Foundation's ALAR studies and ICAO human-factors material both document this phase as the leading contributor to accidents.
- Cruise is the opposite case: low workload, high altitude, and ample time to detect and correct a developing problem, which is why it carries a low accident share.
- Take-off and initial climb are also elevated in risk but have historically accounted for a smaller share of total accidents than approach and landing.
- Mnemonic — 'Down low is where it goes wrong': approach and landing pack the highest workload into the smallest safety margin.

What is the main role of red blood cells?
- AFight foreign bacteria bodies.
- BClot blood.
- CTransport oxygen.
Why that is the answer
Red blood cells contain hemoglobin, which binds oxygen. They carry that oxygen from the lungs to tissues throughout the body. Therefore oxygen transport is their main role in this question.

Frequently asked
How many Human Factors questions are there for the DGCA CPL Air Regulations paper?
Avielevate's bank carries 230 published Human Factors questions for Air Regulations, mapped across 1 learning objective. Every one has its answer key, and explanations are being written across the whole bank.
How much of the Air Regulations paper is Human Factors?
The DGCA does not publish a per-chapter breakdown of its papers, so nobody can honestly tell you — and we will not guess. What we can tell you is what students who have just sat a paper reported meeting, which is measured rather than rumoured: that is the exam recall report inside the app.
What is the best way to revise Human Factors?
Sit a short timed set on this chapter alone, tag how sure you were of each answer, then drill the two that actually leak marks: the ones you got right while guessing, and the ones you got wrong while confident. Avielevate does that tagging for you and puts anything you got wrong back in front of you on a spaced schedule.
