I'm taking some radio freqs for the airports I'm flying into and out

I'm just curious about any problems I might have with the scanner.

Even thought it's not a threat, I wonder if they (TSA) will interpret
it as an issue?

It's not the TSA that will have a problem.

It's pretty unlikely that it will be allowed. For as long as I can
remember, the airlines have prohibited the use of any radio receivers
in flight. Receivers generally contain oscillators which emit RF
noise on frequencies other than those that they're designed to receive.
They can cause interference on radios that use entirely diffent bands.

That said, I regularly use a handheld aviation radio and an AM/FM
receiver in my plane and haven't ever had a problem. That won't get
you very far with the airlines, though.
