The progressed N250 is the Indonesian avionic business' most eager extend yet however in late 1998 looked in threat of stalling because of the Asian budgetary emergency.
IPTN advertised advancement of the N250 at the 1989 Paris Airshow. Model development started in 1992 however by this stage estimations demonstrated that the 50 seater would be overweight, along these lines IPTN chose to extend the fundamental air ship to seat 64 to 68 travelers. At the time just the first model was to be fabricated to the 50 seat N250 standard, consequent flying machine would have been to the bigger N250100 particular. However in late 1995 this arrangement was changed and the 50 seat N25050 was again added to the model line-up nearby the bigger N250100.
Gimmicks of the N250 incorporate flybywire, a glass EFIS Rockwell Collins Pro Line 4 aeronautics framework and Allison AE 2100 turboprops.
The N-270 is an arranged 70 seat, 3m (10ft) extended improvement which would be inherent the USA by AMRAI (American Regional Aircraft Industries). IPTN, General Electric and US speculators built AMRAI to assemble the N270 at Mobile, Alabama however defers in the system have stalled this venture. In 1997 IPTN likewise arranged with Euro Regional Aircraft Industry (ERAI) to assemble the N-250-100 in Germany.
Pa1, the 50 seat first model, first flew on August 10 1995, while Pa2, the first N-250-100 improvement flying machine, started test flying in 1997. Chip away at a third model had essentially arrived at a complete stop by late 1998 and arrangements to fabricate a fourth have been scrapped.
Indonesian accreditation was initially booked for mid 1997 and US certificate for late 1997, however affirmation consistence issues and the Asian money related emergency schemed to defer the system and perhaps stall everything together.
