Sometimes on the approach, depending on which way you come from; joining from IAF, IF, or radar vectors for final, ATC controllers mention the word cleared for "straight in approach."
I tried to look up books and internet, and figured out it has got something to do with approach gate?! and direction you are coming from.
Also, FAA defines the straight in as being on a final approach course within 30degrees of runway.
I will continue to look up for further information, if anyone could clear up this, that would be ideal!
Thank you.
