the highest landing approach speed for any carrier aircraft is typically around 160 knots to 170 knots (184 to 196 mph or 296 to 315 km/h). However, it's important to note that specific landing approach speeds can vary depending on the aircraft type, weight, and other factors.
For example, the landing approach speed for the Boeing 747-400, one of the largest commercial aircraft, is typically around 150 to 160 knots (173 to 184 mph or 278 to 296 km/h). On the other hand, smaller aircraft like regional jets or turboprops may have lower landing approach speeds, typically in the range of 110 to 140 knots (126 to 161 mph or 204 to 259 km/h).
It's worth mentioning that military carrier-based aircraft, such as those used on aircraft carriers by navies around the world, can have higher landing approach speeds due to their different design requirements and operating conditions. These aircraft often have stronger landing gear and higher approach speeds to accommodate the unique demands of carrier operations.
