So HAL has mastered the art of aircraft production and has nothing to learn from anyone else?Production rate is always a function of number of orders. For a mere 40 mk1 order, HAL cannot deliver 36 in one year and 4 in next month, shut the line and ask the skilled workforce to go home and come back after Mk1a or MK2 order is placed. They will stretch it till further orders are placed and work on next type begins. Given the 83 mk1a, they will not deliver 40 per year and shut line after 2 years and go tripping till additional orders of mk1a or mk2 is placed. They have a fair idea of timelines as to when will future orders will come. They will stretch it too. HAL doesn't need the help of Swedish farts for 'aircraft-production 101.'
