Note: We have very limited feedback about this question and the feedback we do have is very confusing, so this question will almost certainly be somewhat different in the exam. Please send any further exam feedback to us using the comments, the feedback section of your dashboard, or by email to [email protected], thank you!

Cyclic loading is the application of repeated or fluctuating stresses, strains, or stress intensities to locations on structural components. For instance, a cyclic load may be on the fuselage on each landing as a result of the impact on touchdown or the force of pressurisation on the fuselage and bulkheads, which increases and decreases regularly per flight. The degradation that may occur at the location is referred to as fatigue degradation or failure. Many of an aircraft's cyclic loads have to be kept track of, to ensure the correct maintenance takes place on the components involved, as degradation is high with these repetitive loads in the same locations.

We are therefore saying that the correct answer here is "cyclic loads", but cyclic loads can also be considered to be dynamic loads as they change in intensity (not static loads), so we think it is misleading to have both options present. The other two options are not even close to being correct.
