My very first cargo jet! Press 8 to toggle the nav lights, and press 1 to activate the emergency parachutes. Also, this has updated the plane Classification of mine. The numbers on the end of a name are now based on part count. If it's a small plane, you add the third digit with the other numbers (139 = 13 + 9 = 22). If it's a small plane, you add the third digit with the other numbers (139 = 13 + 9 = 22). if the answer is still three digits, repeat the adding step until it becomes right. And if it's STILL a three digit number, then just leave it out, idk. Lastly, if it is SOMEHOW the same name as another plane, then just take the number and minus 1. (38 - 1 = 37) Enjoy!
