Vistara's management may have announced steps to tackle its ongoing crisis, but the resolution is expected to take time, sources have told NDTV Profit. Two people familiar with the matter have said that first officers from Air India will be sent to Vistara on deputation. But this may not resolve the matter immediately. These first officers have to undergo compulsory training of nearly 40 days according to rules laid down by the Directorate General of Civil Aviation. This includes a 21-day ground training with simulator and line training.
