Narrative:

I flew the hudson river exclusion route northbound at 1;100 feet past the alpine towers. I had my GPS map zoomed in to provide fine detail boundaries of the hudson river and surrounding airspace. I turned east just south of the tappan zee bridge. I kept my GPS map zoomed in to ensure that I would not violate khpn airspace. Once east of the hpn airspace I applied power to climb to my cruising altitude of 3;500 feet and then 5;500 feet. Since my GPS was zoomed for detail; it did not show the class bravo rings. This oversight resulted in my believing I was outside of class B. It was not until another plane trailing me announced that they inadvertently flew up through the class B floor did I realize that I climbed through the edge of outer ring of lgas class B airspace.lesson learned. Efb's are a fantastic tool. However; as demonstrated above; they allow you to focus on such minute detail to the point where they can impact your situational awareness. Very much like the concept of target fixation. Since I have a panel mounted moving map and an efb my practice will now be to keep one zoomed out if the other is zoomed in. This will provide the perspective needed to avoid a similar occurrence.

Title: A small aircraft pilot operating on the Hudson River Exclusion route inadvertently violated LGA's Class B airspace when the GPS in use was set to a range that did not display the airspace boundaries.

Narrative: I flew the Hudson River Exclusion route northbound at 1;100 feet past the Alpine Towers. I had my GPS map zoomed in to provide fine detail boundaries of the Hudson River and surrounding airspace. I turned east just south of the Tappan Zee bridge. I kept my GPS map zoomed in to ensure that I would not violate KHPN airspace. Once east of the HPN airspace I applied power to climb to my cruising altitude of 3;500 feet and then 5;500 feet. Since my GPS was zoomed for detail; it did not show the Class Bravo rings. This oversight resulted in my believing I was outside of Class B. It was not until another plane trailing me announced that they inadvertently flew up through the Class B floor did I realize that I climbed through the edge of outer ring of LGAs Class B airspace.Lesson learned. EFB's are a fantastic tool. However; as demonstrated above; they allow you to focus on such minute detail to the point where they can impact your situational awareness. Very much like the concept of target fixation. Since I have a panel mounted moving map and an EFB my practice will now be to keep one zoomed out if the other is zoomed in.
