The Jetstream 31 and the Jetstream 32EP are 19-seat turboprop airliners in operation worldwide. The Jetstream 31 entered service in 1982 and the increased power Jetstream 32 in 1988. BAE Systems completed an upgrade programme for the Jetstream 32 resulting in the Jetstream 32EP (enhanced performance) aircraft, certificated in 1997, which has short field capability and hot and high operational performance. Over 400 Jetstream 31/32 aircraft have been delivered.
The enhancements to EP standard are available as an upgrade to Jetstream 32 aircraft and include improvements in the capability of the Goodrich braking system, the installation of drag reduction devices, propeller ground idle adjustment and V speed operation, alternative take-off flap settings and revisions to the flight manual. The enhancements to the braking system provide substantial improvement in the aircraft’s short field performance.
The flight deck has been ergonomically designed for an efficient and comfortable working environment for the pilot and co-pilot. There is a dual flight instrumentation system and the system controls are grouped on the centre and roof panels accessible by both members of crew. The central annunciator panel allows routine system monitoring and reduced pilot workload. The pilots have two direct vision windows that slide open for direct communication with ramp staff.
The Jetstream 31 is fitted with Rockwell Collins Pro Line I avionics. The Jetstream 32EP is equipped with Rockwell Collins Pro Line II with digital control heads.
A number of avionics fits are available as options including a second automatic direction finder (ADF) or distance measuring equipment (DME), a traffic alert and collision avoidance system (TCAS), a ground proximity warning system (GPWS), a Honeywell SPZ-500 automatic pilot and a global positioning system (GPS).
