I am sure that the operators of aircraft are going over their procedures and training as we speak:

Boeing’s 767-based tankers use a version of the pitch augmentation system that grounded the 737 Max 8 fleet, the manufacturer and U.S. Air Force officials say.

The disclosure provides a new data point in the unfolding story of how Boeing installed the Maneuvering Characteristics Augmentation System (MCAS) on the narrowbody airliner fleet.

Both the KC-767 and KC-46 fleets delivered to air forces in Italy, Japan and the U.S. rely on the MCAS to adjust for pitch trim changes during refueling operations.

………

By 2011, Boeing had already delivered KC-767s to Italy and Japan fitted with the first version of MCAS. The use of the system then spread as Boeing won the Air Force’s KC-46 contract in February and launched the 737 Max 8 in August. ………

The U.S. Air Force has launched a review of flight procedures for the KC-46, a spokeswoman says.

“The USAF does not fly the models of aircraft involved in the recent accidents, but we are taking this opportunity to exercise due diligence by reviewing our procedures and training as part of our normal and ongoing review process,” she says.

Oops.
