Lufthansa mulls spot medical checks on pilots: CEO

German airline Lufthansa is weighing possible regular spot medical checks for pilots, its chief said on Friday, after one of them deliberately crashed a jet over the French Alps in March, killing 150 on board.

"Unannounced checks" could be a "possible means" to ascertain whether pilots were regularly taking anti-depressives, which could provide an indication of potential psychological problems, CEO Carsten Spohr told the daily Frankfurter Allgemeine Zeitung.

The surprise nature of the tests would be similar to the doping tests conducted in professional sport, the newspaper suggested.

Spohr insisted, however, that the airline would have to examine very closely "under which conditions and in what exceptional circumstances doctors might have to be exempted from medical confidentiality obligations."

A jet operated by Germanwings, the low-cost subsidiary of Lufthansa, crashed in the French Alps on March 24, killing all 150 people on board in an apparent deliberate act by the co-pilot with a history of depression.

In contrast to other air crashes, "no clear consequences can yet be drawn with regard to onboard safety from the Germanwings crash," Spohr said.

"But of course we are continually working on minimising the risks of flying still further."

Spohr said that the image of the Germanwings and Lufthansa brands had not appeared to have suffered greatly by the disaster.

In fact, "passengers' trust in us actually appears to have increased," he said.
