Report Instrument Training Ground Preparation in Helicopter Flight Training - School Reviews Posted January 25, 2017 How's it going VR members? I currently have my PPL(H) and I am getting prepared to start training for my instrument & commercial helicopter license this summer. Before I start my training I would like to get as familiar as possible with instrument flying rules and regulations. Any suggestions on books or ground programs (King Schools etc)? Any advice/tips are appreciated.
