Most fruit cargoes carried under refrigeration require introduction of fresh air into the cargo space to remove any excess carbon dioxide and ethylene produced by respiration of the cargo and sensors are fitted to detect these gases. Shipper’s instructions will often indicate “constant air change” as a requirement for a cargo. Why, even though this is a crude method for controlling the cargo space atmosphere, is this type of instruction given?
It is the standard method and it is always done that way for simplicity.
Fresh air helps to acclimatise the cargo to the prevailing ambient conditions.
Some cargoes are very sensitive to ethylene levels and it may be difficult to accurately measure the low levels that would affect a cargo.
As much fresh air as possible should always be introduced into the cargo space throughout the voyage to maintain cargo quality.

Feedback for CES v6.0 (Engine Department)
I recently completed the CES v6.0 test for the Engine Department and scored 86%. While the test covers a good range of technical knowledge, I encountered a few significant technical errors and glitches that should be addressed:
Question 75 (Special Survey Interval): The options provided were nonsensical (Beach, Breach, Bleach, Blanch). The system marked \'Bleach\' as the correct answer, which is obviously a technical error. A Special Survey interval is 5 years.
Question 28 (Rocket Parachute Flare): The test lists 180m as the correct altitude. However, per SOLAS LSA Code 3.1.2, these flares must reach an altitude of not less than 300m.
Question 77 (Rust on Ro-Ro units): There is some ambiguity here, as wet vehicles contribute to humidity, but the primary cause of sustained rust in holds is typically the salt-air circulation from the ventilation systems.
I hope this feedback helps in improving the accuracy of the question bank. Thank you
