True or False: Pressure gauges should be solely relied upon for calibrating an aircraft.

Pressure gauges are important tools for monitoring various parameters in an aircraft, including fuel pressure, hydraulic pressure, and more. However, they should not be solely relied upon for calibrating an aircraft. Calibration is a multi-faceted process that often involves multiple data points and systems to ensure accuracy and reliability. This may include adjusting for temperature variations, using other measurement tools, and performing checks against manufacturer specifications.

While pressure gauges provide valuable readings, they can be subject to inaccuracies due to factors such as wear and environmental conditions. Relying entirely on a single type of gauge can lead to potential errors in calibration, which might affect the aircraft's performance and safety.

In aviation, established procedures typically advocate for cross-checking multiple instruments and utilizing various methods to verify measurements and ensure correct calibration. Thus, while pressure gauges are useful, they need to be part of a broader set of tools and protocols for accurate and reliable aircraft calibration, which makes the statement false.
