Final answer:
NAVAIDs and radars that are a part of the National Airspace System (NAS) with the appropriate FSS and affected facilities with at least 24 hours prior notice.
Step-by-step explanation:
The correct answer is option 24.
According to the given information, airfield facility managers are responsible for coordinating preventative maintenance schedules for NAVAIDs and radars in the National Airspace System (NAS). When it comes to coordinating these schedules, they must provide at least 24 hours' notice to the appropriate FSS and affected facilities.
This allows all parties involved to plan and prepare for the maintenance activities.
By giving a minimum notice of 24 hours, the airfield facility managers ensure that the FSS and affected facilities have sufficient time to make any necessary arrangements and adjustments to accommodate the maintenance work without compromising the overall functioning of the National Airspace System.
The correct answer is option that Airfield Facility Managers must coordinate preventative maintenance schedules affecting NAVAIDs and radars with the appropriate FSS and affected facilities with at least 1-hour prior notice. However, the question seems to miss the exact hour requirement.
Based on common standards within the industry, a reasonable amount of time must be given for coordination, which could vary from 1 hour to 72 hours depending on the specific regulations and agreements in place.
Since the question does not provide the exact needed hours, we cannot provide a definitive answer. It's important to consult the appropriate guidelines or regulations that pertain to your specific context.
Concerning the question about your company's contract and time allocation for servicing air conditioners, having a standard deviation equal to the mean time indicates a wide range of service times.
The Central Limit Theorem suggests that with a sufficiently large sample, in this case, 70 units, the sample mean will approximate a normal distribution.
Considering a mean service time of 1 hour and a standard deviation of 1 hour, budgeting 1.1 hours per technician may not provide a sufficient buffer given the variability. It's imperative to take into account the possibility of outliers and the associated risks when budgeting time.
