Blue Sky Star Simulations, also known as simply BSS, have released a major update to their flagship sound-pack for the FlightFactor A320. The changes were originally announced via Facebook yesterday afternoon, along with an appeal for beta testers.

Among the largest changes comes news of a complete overhaul of the engine sounds in 1.3, something that they've kept under wraps until now. Here's the full changelog, as of yesterday;

General Changes

• New wind system
• Empennage wind
• Mid wing and engine nacelle wind
• Nose wind
• All electric contactors remade
• E&E bay transformers sound

CFM56 overhaul

• blades windmill sounds
• complete outside engine sounds all 360 degrees with start/stop sounds (full remade)
• jet blast sounds hitting fuselage while aircraft is on the ground with max power, disappears when aircraft leaving the ground effect.
• Intake rush sounds (smart), depending on thrust input
• Engine spooldown gool, low thrust, spooling down famous CFM sound.
• Custom high thrust that causes engine to whine more at around 70-80% N1 which fades away with more air into cowling and gets replaced by steady "saw" sound.
• N2 Core sounds
• All engine sounds inside change every 3 seats, like they suppose to, basically every PAX seat has its own authentic sound of engine.
• Jet blast rumble (back)
• Reverse sounds
• CFM buzzsaw fixed volume.
