A life insurance aviation exclusion clause typically restricts coverage for death caused by:

Why A is correct

An aviation exclusion clause generally restricts or eliminates coverage for death resulting from flying in private or noncommercial aircraft, which poses a higher and less predictable risk than scheduled airline travel. Commercial airline passengers are usually covered because the risk is considered standard. Insurers may exclude private-pilot and noncommercial flying unless the insured pays an extra premium or obtains an endorsement removing the exclusion. The clause reflects the underwriting view that private aviation is a hazardous activity relative to standard occupations and travel.

Why the other options are wrong

• Scheduled commercial airline flights are generally covered; the exclusion targets the higher-risk private and noncommercial flying activities. This answer describes a different situation from the one in the question and is therefore incorrect under the facts given here.
• Excluding all air travel is unusual; standard policies cover commercial flight as an ordinary risk while limiting only noncommercial aviation. This choice does not fit the arrangement described in the question, so it is clearly not the right option to choose.
• Travel by train or bus is not aviation risk at all and is not addressed by an aviation exclusion clause. Accordingly, this option is not correct because it does not match the specific rule or product that is described in the question.

Memory hook

Commercial flight is fine, but private flying gets the aviation exclusion.
