MEL question
I am currently flying an AS350 part 91 in the U.S.
I looked up the Master MEL and do not find any references to caution lights except the door and generator lights. I understand that the MEL is not required when flying part 91 and only 91.205 (I think this is the right section) applies concering minimum equipment for Day VFR, etc. Now my question is this. Am I correct in assuming that it would be technically legal (although not smart) to fly the AS350 without certain caution or warning lights like the Main Gear Box Pressure or Temp light? My question relates to a situation where you landed out in the field, only to find on the restart that one of these was inop. Could you fly back to base so that it can be addressed? ps. there are no MGP or MGBT gauges. Thanks for helping me out.
