Water, Water Everywhere

While retrieving the airplanes paperwork and keys, I was told its airspeed indicator (ASI) was acting up. It was reading low, according to the FBO, and the airplane was due for some shop time later that day. The shop hadnt opened yet that morning, though, and I had plans later in the day, making a delay problematic. I asked if the airplane was grounded. No, was the response.

Key Takeaways:

A student pilot flew a cross-country flight in a Cessna 150 despite being informed its airspeed indicator (ASI) was faulty and reading low, completing the trip by relying on groundspeed checks and cautious flying.
The ASI malfunction was caused by a small amount of water in the pitot system, which was easily cleared by a mechanic, highlighting the importance of protecting aircraft pitot tubes.
The incident serves as a critical safety reminder that pilots should not fly aircraft with known malfunctions and FBOs need better-defined maintenance procedures, as poor judgment could lead to severe consequences.

I was still a student pilot, past my first solo, but working on building cross-country time. The day’s plan was a solo round-trip flight to a towered airport about 100 miles from home base. My chosen platform was a well-worn but mostly reliable Cessna 150.
