747N

747N refers to a specific variant of the Boeing 747 aircraft, often designated as the Boeing 747-400ER, where 'ER' stands for Extended Range. This model is an enhanced version of the popular 747-400, designed to offer a longer flight capability. The primary distinction of the 747-400ER is its increased fuel capacity, achieved through the addition of a new optional fuel tank in the lower cargo hold, as well as structural strengthening to accommodate the extra weight.

This extended range allows the aircraft to fly further non-stop routes than the standard 747-400. This capability is particularly valuable for airlines operating long-haul international flights, enabling them to connect distant city pairs that might not have been economically feasible with previous models. The 747-400ER retains the core features of the 747-400, including its distinctive stretched upper deck and advanced cockpit. While not as numerous as the standard 747-400, the 747-400ER has served important roles in cargo operations and passenger service on ultra-long-range routes.
