Cho, daughter of the airline's boss and herself a KAL executive at the time, ordered the chief purser off a December 5 New York-Seoul flight and compelled the taxiing plane to return to the terminal gate so he could disembark.
She had taken exception to being served macadamia nuts which she had not requested -- and in a bag, not a bowl.
"The plane was forced to change its planned line of movement and the chief purser, who was on duty to ensure flight safety, had to leave the plane, causing safety hazards," senior prosecutor Kim Chang-Hee told journalists.
Cho is charged with forcing the flight to change its planned movements and using violence against crew members, both breaches of an aviation safety law, as well as obstructing official duties by leading the company's attempts to cover up the incident.

If convicted, she could face up to 15 years in prison but legal experts said she would likely draw a suspended jail sentence.
Cho, 40, was arrested and jailed on Tuesday last week after a local court issued a warrant, citing "the gravity of the issue as well as the organised efforts to cover up" the case.
Cho is one of three children of KAL boss Cho Yang-Ho, who is also the patriarch of business conglomerate and KAL's parent company Hanjin Group.
She has publicly apologised for the incident and resigned from all her posts at Korean Air and its affiliates.
Prosecutors also brought charges against a Korean Air executive surnamed Yeo for his alleged involvement in Korean Air's attempts to eliminate evidence.
A transportation ministry official who leaked details of a government probe into the case to Yeo was also indicted.
Prosecutors said they would investigate allegations that government officials got free upgrades to business-class seats from Korean Air.
