VTOL can fly even without the use of an airport that regular aircrafts use. It can take you from a certain point of origin, taking off vertically, and proceed to a point of destination where you land vertically as well. This is different from a local flight where you have to go to an airport, then the plane will fly you to another airport, then you take a car to your real destination. Much time is saved from traveling to and from the airport with VTOL. With VTOL planes, you land where it is nearest to your destination.
VTOL has application in other areas other than in travel. VTOL is also useful in rescue operations and in military and law enforcement applications. In these applications, we see clearly the importance of taking off and landing at particular locations rather than an airport.
The construction of VTOL is not as easy as a conventional winged plane. It is more difficult technically. But its advantages are numerous. Here are the advantages of VTOL.
With VTOL, you can take off and land in many more places than a regular plane that requires an airport. Much time and fuel from going to and from the airport is saved with VTOL. If you live in the US, it takes around 17 miles of travel to reach the nearest airport. If you use a VTOL plane, you don’t need to go to an airport, since there are areas less than a mile from your home where a VTOL plane can take off or land. Taking a VTOL plane will not require you to travel 17 miles to the nearest airport.
You get a faster and more efficient plane in a VTOL. And the reason for this has to do with the use of the wings. A large wing produces drag. If the plane increase speed, then drag also increases. More drag is caused by friction on the wings. More fuel is burned by the plane but its speed is reduced because of drag. But VTOL wings are not used for takeoff and landing. Their design is optimized strictly for speed and efficiency. VTOL planes are faster and more efficient because their components do not cause drag.
During takeoff and landing, the plane is at high risk of accidents. This is the most dangerous parts of a flight. When the plane is cruising at high altitudes, then the plane is at its safest point. The most danger lies when the plane is close or rolling on the ground at high speeds where there is very little margin for error. This is why takeoff and landings are very dangerous despite having vast space in airfields. This does not happen with VTOL planes because of their vertical takeoff and landing. With its acceleration and deceleration happening in the air, the risk is greatly reduced.
