In the 414, yes. The avionics bay is just aft of the nosecone, and the nose baggage compartment is just behind that. Both are located forward of the pressure bulkhead.
Weight & balance charts specify different stations for the "avionics cargo" area and the "nose cargo" area. FS 32.00 and FS 71.00, respectively.
Quoting Hatbutton (Thread starter): Are the two compartments separated or do they just invisibly separate the the two?
In the 414, the avionics bay is separated by a single, one-piece panel, but I think some are located underneath the baggage area floor.
Quoting Hatbutton (Thread starter): As for the Aft cabin A and B shelf. What exactly does that mean? From pictures I've seen of the 402C, if you have an 8 seat interior there isn't any space in the back to put bags is there?
Well, I finally just decided to scan this for you...pictures speak louder than words:
My study guide states that the aft cabin baggage area has a capacity of approximately 500 pounds distributed evenly side to side. It also states that the weight of seats seven and eight or the aft refreshment cabinet must be subtracted from the total baggage weight weight allowable in this area.
I know this is all 414 info, but hopefully it will help you out.
