After a Times of India probe, it was found out that Air India is training Dreamliner pilots with a faulty simulator. As the airline is tight on cash, they are training new Dreamliner pilots warning signs, emergency response, fire alarms and other calamities they might face while in air using a simulator. The executive director of training, however, has instructed the engineers, pilots and instructors to not report a warning sign as a flaw in the log book.
The warning sign in question is related to the Inertial Reference System or IRS (navigation system). The warning signal means that the IRS is running on battery which means it could shut down any moment when the battery runs out. The issue over the warning is that according to Air India sources, the warning light is wrongly lit as the IRS keeps on working for a number of days which would not be possible if the IRS was really on battery. But in real life scenario, the “IRS on BATT” signal would means the aircraft could not take off. Hence telling pilots to ignore it could have real life implications. Also after the TOI probe, pilots were told to log the warning but the signal was not actually fixed.
