different TBs require different type of planes
you have to click on that arrow to the left of AIR DAY or AIR NIGHT and you will see what you need
some TBs might need only fighters while another might require fighters + patrol (which is recon and naval patrol)
as for a planes there are no CV
this is what i also mentioned some time ago
so in order to roughly estimate how many planes do you need to send you have to count existing planes in particular TB and divide by current value that they contribute
it should work fine if planes in this TB are the same type (like modern one, which in case of the Axis is probably the case, good luck trying to do it with a Soviets with an auto upgrades in TBs
