Well done. I agree with Night Rider entirely. I find most PPL's, and even some CPL holders, will try to save themselves the 'stress' of flying with you and some money, by telling you they're brilliant and know it all. Encourage them to prove it to you, but be wary at all times. Remember, if in doubt in any way or form, dont let them go by themselves. Thats it in a nutshell really. Remember, you are the pilot in command and when you sign someone out solo, you are morally responsible for their actions. As for easing into the task, trial flights and flights with green pilos are best for building your own confidence and honing your new skills. This should be done with the encumbance of a senior instructor, who should help you out at all times in the early stages. I really didnt feel totally confident until I had about 150-200 hours instruction time. All the best and good luck with your new job.
