Old plane satisfactory in a little soaring (6)

I believe the answer is:

dakota

I'm a little stuck... Click here to teach me about this clue!

Here is my best explanation:

'old plane' is the definition.
'dakota' can be an answer for 'plane' (I've seen this before). I'm not sure about the 'old' bit.

'satisfactory in a little soaring' is the wordplay.
'satisfactory' becomes 'o.k.' (similar in meaning).
'in' is an insertion indicator.
'little' becomes 'tad'.
'soaring' is a reversal indicator (in a down clue, letters 'soar' up).
'a'+'tad'='atad'
'ok' put inside 'atad' is 'atokad'.
'atokad' backwards is 'DAKOTA'.
