The new Q400 NextGen turboprop airliner is the next step in the continuing evolution of the Q400 aircraft. As with the CRJ NextGen aircraft family, the overall cabin environment of the Q400 NextGen aircraft will be brightened with the introduction of LED lighting while highlighting the improved aesthetics with new ceiling panels and dished window sidewalls. The already spacious interior of the Q400 NextGen aircraft will be further enhanced with the introduction of larger overhead bins that will accommodate standard roller bags. Combining these features with the Active Noise and Vibration Suppression (ANVS) system will give the Q400 NextGen aircraft passenger an even more pleasant cabin experience.
Operating costs of the Q400 NextGen airliner, already among the lowest of any regional aircraft, will be made even lower by increasing the scheduled maintenance intervals and further optimizing maintenance tasks to reduce downtime during the aircraft’s life cycle. The Q400 NextGen airliner Aircraft Operating Manual (AOM) will be updated to reflect flight test experience which has shown that the fuel burn under certain operating conditions is lower than predicted.
The Q400 aircraft is already the most technologically advanced turboprop airliner and the NextGen features will make it even more so. The Q400 NextGen aircraft is the turboprop airliner for the twenty-first century.
he Q Series aircraft are the quietest turboprops flying today, thanks to the development of a revolutionary Noise and Vibration Suppression (NVS) system. Not only does this NVS technology significantly reduce noise levels, it also reduces cabin vibration, making the flight as comfortable as possible.
Advanced Avionics
The Q400 cockpit, the most modern of any turboprop, is fitted with a state-of-the-art avionics suite from Thales. With less weight and fewer parts, the Thales suite offers higher reliability than comparable older technology avionics.
The Q400 avionics suite also features a centralized diagnostic system to help pilots and mechanics quickly resolve problems. Its modular design also makes the system easy to upgrade or to add optional equipment.
An optional Head Up Guidance System (HGS®) displays actual aircraft approach flight path and projected touch down point. The system is allowing Horizon Air to fly single-engine approaches to Category III (Cat. III) weather minima - a first for a commercial regional airline aircraft.
Powerful and Innovative Engines
The Pratt & Whitney PW150A engine is the most advanced turboprop engine currently in production. Based on the PW4000, it is built with a blend of smart technology and low complexity, offering a new standard in reliability, durability, and operating economics.
Features include Full Authority Digital Electronic Control (FADEC), centralized diagnostics, low fuel consumption & emissions, new technology materials & cooling and low parts count for reduced complexity.
And while the PW150A produces nearly twice the take-off power of older turboprop engines, it is nearly 50 per cent more fuel-efficient.
High Technology Propellers
The Q400 features six-bladed all composite Dowty propellers that deliver more thrust and less noise than smaller propellers turning at higher rpms. Made from a new generation of lighter and stronger materials, these slow moving propellers are mounted further out on the wing to help reduce noise levels.
Hard to believe, but the quietest place in the cabin is between the propellers.
