## 3 Applications in UAM
Similarly, cargo delivery aircraft may need to travel long distances to reach their destination or short distances for small packages. While not as critical as for emergency response missions, speed is still an important consideration for cargo delivery aircraft. Faster aircraft can deliver cargo more quickly, which may be an advantage in most situations. Aerial surveillance aircraft need to be able to stay in operation for extended periods of time, allowing them to monitor a specific area over an extended period. So usually, they need long endurances. They may need to fly at a specific altitude to get the best view of the area being monitored. The flight height requirement will depend on the specific mission and may be influenced by factors such as weather conditions and local regulations. But it is usually low in UAM applications like traffic monitoring and similar missions. Due to the nature of their missions, these aircraft may carry a variety of sensors and cameras to monitor the area being surveyed. However, high cargo capacities are not expected in these applications. Regarding maneuverability, these missions depend more on stability rather than agile movements. They may also need to be able to operate in harsh weather conditions, such as high winds or heavy rains, although this may not be a common requirement among the majority of missions. For entertainment missions, the comfort of passengers is a key requirement. Passengers on entertainment flights are looking for a comfortable and enjoyable experience. The aircraft then, should be designed with characteristics such as high stability and robustness to weather changes, in-flight entertainment, and comfortable seating. Entertainment flights are often focused on providing passengers with a unique view of the surrounding area. The aircraft is expected to have large windows or other features that provide passengers with a clear view of the area being toured. They are also required to provide a noise-free or low-noise flight regarding their nature. Considering all the requirements mentioned for different UAM applications and the specification of current configuration it would be possible to sort the best configuration for each solution. Personal vehicle and family transportation needs small aircraft with VTOL capability for transporting up to 4 passengers. Since the multirotor, dual system, and helicopters seem to be good configurations. From other configurations cyclocopter and Magnus-effect can also be considered for these applications because of their VTOL (short runway about Magnus-effect) capabilities, small size, and payload. For air-taxi, configurations like tilt-rotor, helicopter, and tilt-wing are more suitable because of their higher number of passengers and flight range. For larger transportation, fixed-wing and lighter-than-air configurations are the best solutions due to their high speed, range, endurance, cargo capacity, and number of passengers. Although few researchers and companies are working on morphing-wing configurations for larger transportation, the higher efficiency and adaptability they provide can make them suitable options for larger transportation. In emergency response, we need a quick response with high-speed aircraft which are able to travel long distances. A hover flight capability would be a very helpful specification in many cases like firefighting or surveying the crisis area. Considering these requirements helicopters; hybrids, and multirotors are suitable configurations for emergency response. Researchers have shown the capabilities of helicopters to satisfy a rapid-acting necessary for flood rescue [99]. Considering the hovering flight, higher range, cargo, and speed than VTOLs, gyrodyne seems to be a considerable solution as well. When it comes to cargo delivery, we may need a wide range of aircraft for small to large packages. This application does not have any specific range and endurance, so depending on the mission the aircraft may travel a short or long range.
