Hello,

Airliners dont have to change course that much in a horizontal way, I meant they have to change altitude in order to avoid other flight's, they will sometimes deviate if there is on-comming traffic and also weather factors come into play when avoiding a thunderstorm for saftey reasons etc.

Many of todays pilot helmets are made to a high quality standard. They are also well insulated to prevent noise such as you mentioned and to stop damage occurring to the ears. Seeing the F-16 flying in real life when your not so far away from the plane is loud enough, much louder than from the cockpit. It is a bit strange that you mention it is loud inside the cockpit Run, not because I doubt you but because the engine is further back than where the pilot is sitting. I wonder if the shape of the canopy comes into play here with acoustics, this why it probably sounds loud in the pit. I am sure that when you were flying your F-16 Run, you get to know that aircraft well. You know all the strange sounds and knock's that make that aircraft. They should have designed the F-16 with more insulation, but being a military aircraft is no surprise, they are built like this.

The sounlevel in the f-16 is extremely high when you don't have the helmet on. I once had the engine started without any earprotection and that really hurt my ears. Even with the helmet on a lot of guys wear earplugs in order not to get too much noise. The noise though is mainly engine & ECS (Environmental Control System) related and not so much airnoise. With the helmet on the noise is a lot more pleasant than what you find in a small propaircraft.
