How to start with camera and Airplane for the game ?

This really depends on exactly what you want to do- if your plane is locked into a set path, then just make the camera fixed and move the plane relative to the camera. The camera follows a set rail, the plane moves around in front of the camera.

Yah but in strike 3d game if plane scrolls left and right camera also scrolls now that's where i have got stuck ... I have tried possible solutions

First I created script for Airplane which will have target camera...s that camera will move according to the airplane... But now While doing this I faced problem that my camera will behave like FollowCamera i.e. Airplane will always be in center of the camera and it will not be able to move freely in the provided place ...

So I chuck that plan and started writing script for Camera Where I took Abs(camera.position - target.position) > scrollDistance) ... and I started moving camera but now while doing this I am facing two issues camera is not scrolling properly its getting jerk in between

now I tried to do Mathf.SmoothDamp but this makes my camera scrolling too slow ...I tried changing the values of smoothVelocity etc.. but still facing the issues of jerk and slow motion...

So i m stuck now are my logics right ? or maybe I have done too many things with camera that I am stuck ...

You duplicated your comment there, might want to fix that...

I think you need to sit down with a piece of paper and a pencil, and work out exactly what it is you want your game to do.
