Ongoing aircraft appearance is more than just a first-impression. Washing, polishing and managing your aircraft's exterior can have significant impact on performance that adds up to real savings. Removing parasitic drag by dry-washing makes an enormous impact on airflow, greater than wet washing.CAS' aircraft appearance services are all crafted with an eye to the environment.Our dry-washing procedure is approved by the EPA to wash at any airport - even at the gate. Our products are biodegradable and our operating procedures help prevent ground contamination. But it is not only in how we service your aircraft, it is the result our service has on your aircraft.
