Airbus Helicopters H155 vs Airbus Helicopters H160 vs Boeing Bbj 777x vs Leonardo Aw139 vs Leonardo Aw169 vs Sikorsky S 76d

The Boeing BBJ 777X is a long‑range VIP airliner, far exceeding the helicopters in category, range, and capacity. It is intended for intercontinental missions, typically offering several thousand nautical miles of range and accommodating dozens of passengers (often configured well below its airline maximum for VIP comfort). All the others are twin‑engine helicopters aimed at regional transport. The Airbus H155 is a medium twin with typical range in the few‑hundred‑nautical‑mile class and usually seats around 12–13 passengers. The Airbus H160 is a newer medium twin in a similar passenger bracket (about 12), generally offering comparable or somewhat improved range and efficiency depending on configuration. The Leonardo AW139 is a popular medium twin that often carries roughly 12–15 passengers with similar few‑hundred‑nautical‑mile ranges. The Leonardo AW169 is a smaller intermediate/light‑medium twin, typically configured around 8–10 passengers with slightly shorter range than the AW139 class. The Sikorsky S‑76D is a medium twin commonly used for executive and offshore roles, usually seating about 8–12 passengers with range also in the few‑hundred‑nautical‑mile range.
