Answer: Daytona Beach, Florida (on Florida's East Coast)
Step-by-step explanation:
The pilots should expect smaller daily temperature ranges at Daytona Beach because seaside areas are usually cooler as a result of wind from the body of water next to it cooling it down. In the case of Daytona beach, the Atlantic Ocean will be cooling it down.
This is in contrast to Prescott in Arizona which stands at a height about 5,000 feet elevation. Prescott will experience higher temperature ranges due to its elevation. Higher altitude areas are generally known to be hotter because the solar radiation is more there as it is closer to the atmosphere.
