When it flies upside-down fuel flows from a collector tank in the fuselage and the inverted flight is limited to 1 min. Deepak has a theoretical glide ratio of 8.5:1. The IAF and HAL are looking into new safety systems such as Ballistic Recovery Systems to enable it to descend safely in the event of an engine failure. On 16 May 2010 the IAF cleared the installation of a parachute recovery system.[2] The HPT-32 aircraft has been replaced by the Pilatus PC-7 Mk II in the IAF, as its workhorse as a Basic Trainer Aircraft (BTA) in 2013.
