Multiple Choice

Which pitot tube is designated for ESIS use?

The left pitot tube, designated as #1, is specifically used for the Electronic Standby Instrument System (ESIS) in the TH-73 helicopter. The reliance on the left pitot tube provides necessary airspeed data that the ESIS relies on to function independently of the primary flight instruments. In the event of a failure of the primary systems, the ESIS can utilize the data from this designated pitot tube to ensure that essential flight information remains available to the pilot. The importance of using a specific pitot tube relates to the redundancy and reliability features incorporated into the helicopter's design. By designating the left pitot tube for ESIS use, it ensures that this system has a dedicated and proven source of airspeed data, which is critical for maintaining control and safety in various flight scenarios. This clear allocation helps to mitigate risks associated with instrumentation failures and enhances pilot situational awareness.
