The system prepares the aircraft for start up in cold weather operations.

Tanis Aircraft Products’ preconditioning system for the Erickson S-64 Aircrane has received an STC from the FAA.

The company noted that preconditioning adds to operational reliability, safety, utility, and reliable starts in all weather conditions.
