What information is typically included in a deice communication?

The inclusion of the time of final application in a deice communication is vital for several reasons. Knowing this information helps all parties involved in the pre-flight process understand precisely when the deicing fluids were last applied. This is critical for ensuring the safety and effectiveness of the deicing procedure, as the timing directly affects the potential for frost, snow, or ice to accumulate on the aircraft prior to takeoff. Adequate knowledge of when the final application was completed allows maintenance and flight crew to make informed decisions about the aircraft's readiness for departure, particularly in adverse weather conditions.

The other choices, while informative in different contexts, do not pertain specifically to deice communications. For example, a weather forecast may be useful for flight planning but does not specifically address the status of deicing. The passenger load factor and pilot flight hours, while essential aspects of overall operational considerations, are irrelevant to the immediate concerns surrounding the deicing process and the safety of the aircraft during takeoff. Thus, the time of final application is the most pertinent and critical information within the deice communication context.
