Delta has trialed different technologies, including aircraft structure-monitoring sensors (SMS) and drag reduction. Are there other new technologies you’re evaluating?

There is not a ton of new stuff because COVID-19 really slowed everybody down. We have an ongoing implementation of the SMS comparative vacuum-monitoring sensors on the aft pressure bulkhead of the 737-800. So far, 23 of 77 aircraft have these sensors installed. Instead of taking the whole back of the airplane apart to complete an inspection, the sensors enable us to inspect for cracking without the need to remove galleys or other
monuments to access the inspection area. This significantly reduces aircraft out-of-service time and enables us to provide more aircraft back to our network by reducing special scheduling that is typically required to accomplish the manual inspection method.
