New Delhi, July 28 -- Air India has asked its pilots to ensure rules are followed during their mandatory annual test, officials told HT on Sunday. In an internal email to the pilots, seen by HT, the airline also informed them that it is upgrading its training and rostering software. The internal email, sent by the director training late night on Saturday, is a notice to all pilots stating that the airline is upgrading the CAE system. CAE, a Canadian simulator company, is a pilot training management platform used by airlines. The notice read, "..This step is being introduced as an additional mitigation measure, while our planning teams continue to monitor the process closely as well." "Pilots have been asked to double-check their assigned trainer for Annual Line Route check (ALC) against their previous ALC record," an official aware of the development said. ALC is a yearly flying test for pilots where a senior trainer flies with them during a regular flight to see how they perform. The test is done on an actual flight. A second official aware of the matter, however, said that the software upgrade triggered the email to the pilots. "Civil Aviation Rules mandate pilots to perform these annual tests with different trainers every year. Since the software is being upgraded, automated safeguards may not be fully functional."...
