Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. The original TIEs were designed to attack in large numbers, overwhelming the enemy craft. The Imperials used so many that they came to be considered symbols of the Empire and its might. They were also very cheap to produce, reflecting the Imperial philosophy of quantity over quality.
However, a disadvantage of the fighter was its lack of deflector shields. The cockpit did incorporate crash webbing, a repulsorlift antigravity field, and a high-g shock seat to help protect the pilot, however these did next to nothing to help protect against enemy blaster fire.
Due to the lack of life-support systems, each TIE pilot had a fully sealed flight suit superior to their Rebel counterparts. The absence of a hyperdrive also rendered the light fighter totally dependent on carrier ships when deployed in enemy systems.
While the ships were structurally capable of "sitting" on their wings, they were not designed to land or disembark their pilots without special support. On Imperial ships, TIEs were launched from racks in the hangar bays. The high success rate of more advanced Rebel starfighters against standard Imperial TIE Fighters resulted in a mounting cost of replacing destroyed fighters and their pilots.
That, combined with the realization that the inclusion of a hyperdrive would allow the fleet to be more flexible, caused the Imperial Navy to rethink its doctrine of using swarms of cheap craft instead of fewer high-quality ones, leading to the introduction of the TIE Advanced x1 and its successor, the TIE Avenger. The primary duty profile included attack and escort task, but also reconnoiter missions.
