Oz. You don't say which modelling program this is. I assume the texture is a photo wrapped around the front of the head. In this case, try stretching the photo image or extend it by adding borders to it. This will allow it to fit around the object properly. You will need to experiment. Use existing pilot textures for reference.
PS. To show you what I'm getting at I quickly hashed this up from the CFS2 default US pilot.
