How can you receive a weather update while preflighting your aircraft at Fresno Chandler Executive (FCH) when fog rolls in?

Receiving a weather update while preflighting your aircraft is crucial for ensuring safety, especially in changing conditions like fog. One reliable method in this scenario is to contact Rancho Murieta radio on VHF 122.2. This frequency is typically designated for receiving real-time updates from a source that is specifically tasked with disseminating aviation weather information. Such communication allows pilots to obtain precise, current weather conditions that can affect their flight preparation and decision-making.

Other choices may not provide the same level of reliability or up-to-date information. For instance, using the airport’s weather station may yield data, but it could be less timely than direct communication with a radio service. Similarly, while checking a weather app on your phone can give general weather trends, it might not reflect the current, localized conditions at the airport. Asking a nearby pilot for their observations can also be helpful, but it relies on the subjective qualifications of that pilot and their awareness of the latest weather changes. In contrast, using dedicated aviation communication ensures access to the most accurate and specific data needed for flight safety.
