By loading/unloading you talking of flying/transfering planes between a base vis a vis loading planes on as when tranport them?
Must be carrier capable type and/or float planes?
CS only carry Float Planes afaik. By unloading, I mean...
At game start you have 3 CS. Two (Chitose and Mizuho?) are in a TF at Palau that is set to hit Legaspi in the northern Phillipines and one (Chiyoda?) is in the same port in Japan where CVL Zuiho and CVE Hosho start the game. I forget which base it is, but it is probably Hiroshima/Kure.
What I do first is transfer the Pete squadrons off of the CS to a base. Iirc, the one in Japan goes to Amami and eventually heads south to take up ASW duties along the convoy routes between the SRA and Japan. The ones in Palau get boxed up and forwarded to locations where I can use them for ASW.
I then take longer range FP's off bases within xfer range and transfer them onto the CS's. Make sure you cover the gap in your patrols caused by this xfer. The one in Japan is easily handled - I take a nearby unit of 27 Alf's, split it into 3 groups and xfer two of those groups onto the CS, giving me 22 total (4xE13A1, 2x9xE7K2) float planes on a CS with capacity of 24. The two at Palau are a little more difficult to handle since you either have to transfer the float planes in from islands nearby, creating holes in your patrol coverage, or send some replacements in via AK/first turn movement.
I am left with 3 CS with ~22 long range float planes that can perform scouting/ASW services for ACTF's and free up Vals/Kates to attack/rest. When Nisshin arrives in the January time frame, I use her as the flagship of a TK convoy that plies the routes from Japan to SRA and back.
