I had this doubts watching the last PSLV-XL launch . Please clarify it .
1. Between the 2nd and 3rd or 3rd and 4th stage (I don't remember correctly where) , there was a coasting phase. The rocket was flying without any power for almost 200sec. Is this phase present in every launch or just limited to the XL version ??
2. Also the shroud of the rocket covering the satellite was removed at a height of some 120+ km . Is it because the atmosphere ends there and rest is vacuum , So the shroud is a dead weight without any purpose ???
