At 6:52 on May 14, 2022, the C919 aircraft numbered B-001J took off from the 4th runway of Shanghai Pudong Airport and landed safely at 9:54, marking the successful completion of the first flight test of COMAC's first C919 large aircraft to be delivered to its first user.

It is a great honor for Panran, as one of the formulation units of China's temperature measurement standards, to provide temperature measurement solutions for China's C919 and C929 aircraft. Our customer are China's military industry, national metrology institutions, petrochemical and other large units. We have more than 20 cooperation projects with aerospace, and many temperature measurement solutions of them are from Panran.

According to COMAC, during the flight of 3 hours and 2 minutes, the test pilot and the flight test engineer coordinated and cooperated to complete the scheduled tasks, and the aircraft was in good condition and performance. At present, the preparations for the test flight and delivery of the C919 large aircraft are progressing in an orderly manner.

Congratulations on the successful completion of the first flight test of C919. Looking forward to the further development of China's aerospace industry, China's aerospace industry is thriving and constantly breaking through and innovating. Panran will also uphold its original intention and continue to contribute to China's temperature and pressure measurement.
