Ef­fort to make Te­jas more ‘In­dian’


In a con­certed ef­fort to re­duce the per­cent­age of for­eign com­po­nents in the In­dian LCA Te­jas fighter, the Aero­nau­ti­cal De­vel­op­ment Agency (ADA) has drawn up a com­pre­hen­sive list of 111 air­craft line-re­pla­ca­ble units (LRUs) that will be in­di­genised and built by In­dian com­pa­nies within the coun­try. The am­bi­tious list in­cludes 21 avion­ics com­po­nents (in­clud­ing gyro ref­er­ence unit, tac­ti­cal nav­i­ga­tion an­tenna and GPS an­tenna), 27 en­vi­ron­men­tal con­trol com­po­nents, 14 elec­tri­cal com­po­nents (in­clud­ing un­der-car­riage dis­play unit, in­te­gral drive gen­er­a­tor and ground power re­cep­ta­cle), ejec­tion seat, nine com­po­nents in the flight con­trol area (left and right air data sen­sors, an­gle of at­tack sen­sor, sen­sor assem­bly rate). The list also in­cludes sev­eral key LRUs in hy­draulics, land­ing gear, propul­sion & fuel, and the air­craft’s health and util­ity man­age­ment sys­tem. In a state­ment an­nounc­ing its in­ter­est, the ADA has said, “There are 358 LRUs (com­po­nents) in the Te­jas air­craft, out of which 53 per cent of to­tal LRUs are in­dige­nously de­vel­oped within In­dia. In view to re­duce the re­main­ing 47 per cent of the im­port LRUs, ADA has ini­ti­ated the In­dige­nous de­vel­op­ment pro­gramme for in­di­geni­sa­tion of the im­port LRUs.”
