We’ve put most of the current portable GPS offerings through the ringer with an eye to how they support instrument flying. Some are compact and capable, like the basic AV8OR from Honeywell or Anywhere Travel Companion (ATC) from Control Vision. Some are so big they are more like portable MFDs: Trueflight’s FL 210 or most of the EFBs that run on tablets fall into this group. In the end, we liked the aera and 296 through 496 Garmins the best, with a possible exception for the Honeywell AV8OR Ace.
