High-decker (omnibus)
As a high-wing aircraft are coaches called that have a high center of the passenger compartment. This design allows a better view for the passengers and, in particular, an increased capacity of the storage spaces that are located below the passenger compartment (underfloor). The service fixtures such as the toilet and the kitchen are usually located in the underfloor area. Some buses also have a bunk for a second bus driver under the floor .
The term was coined in 1971 by Auwärter Neoplan , who presented this new concept for the first time with the introduction of their Cityliner . The design was quickly adopted by the entire industry and is also the most common design for current coaches.
An extended design are the super high-decker or ultra-high-decker , in which the bus driver's cab is located completely in the lower deck, i.e. below the level of the passenger compartment floor.
