Difference between a KLN 90 and 90B?
 

Am I correct in that a KLN 90 is approved only for Enroute/Terminal operations (A2), where a KLN 90B is approved for approaches also (A1)?

Flying an airplane this week with a KLN 90, and trying to figure out what / to file. I know /G is for GPS/GNSS systems with approach capabilities.


Thanks

You are correct, the 90 is terminal/enroute, while the 90B add's approach capability. You can still file /G, because you can navigate direct anywhere via the GPS. You will just need to have the appropriate approaches available to you at your destination if the weather isn't VFR.
