Description: FS2004 sounds. Hey everyone! My name is Joe Maciejewski, and ive been simming since Flight Simulator 98, I love aviation and plan to become an airline pilot, I am 16 years old. Anyway In all the Sims, There has been a lack of something, The lack of the rumble of the runway, the lack of the clacking of loose things while rumbling down the runway at over 160 MPH. So I FINALLY decided to make a rumbling sound while in the cockpit. This is a real recording while in the cockpit of a United Airlines 777-200 I hope it will meet your demands for more real sounds on the ground. :)
737ng_enhancement.zip Description: 737NG Enhancement Package by Des Braban This file is an enhancement to my 737NG sound package. Here we find the correct buzzing avionics sound, improved landing gear sound and flap sound. There is also one or two little surprises included. Raise the landing gear and you hear the captain announce Positive rate, gear up you will also hear him call gear down when lowering the gear. As an added bonus, he will also call engine startups and engine stability upon starting. Just a little something which I included for your enjoyment. please note, you must have the 737NG sound package to complete this file.
