TATA-owned Vistara Airlines gets another major blow from aviation regulator DGCA when the airline already has a stretched pilot roster. Training of about 30 Vistara pilots is on hold after the civil aviation regulator asked the airline to explain the alleged violation of rules. The pilots were slated to operate Boeing 787 aircraft, which the airline uses on European routes.

The Directorate General of Civil Aviation (DGCA) has raised questions over a procedure called Zero Flight Time Training (ZFTT). When a pilot has to undergo conversion training for operating a different type of aircraft, he has to undergo multiple stages of training. A Vistara spokesperson confirmed it has received a show-cause notice from the regulator, stating, “We are in receipt of a show-cause notice from DGCA and are in discussions with the regulator on this subject,”
