# Where is V15 and how do I find it?

My question: Where is V15 and how do I find it?

The question referred to in the practice test:

Refer to the figure 21, area 2 below: What is the floor of controlled airspace along V15?

The correct answer was 1200 ft AGL.

I want to thank @757toga, and @JScarry for the help on this. I made an 88 on my Drone certification that I took today (10/11/2018)

There is a notation for V15 (low altitude IFR airway) in the southern portion of the top map in your question.

V15 is a Federal Airway, normally used for IFR operations and shown on IFR charts as well as VFR Sectionals. Federal Airways, unless otherwise notated, begin at 1200 AGL. These airways are Class E airspace. If you look in the legend of your Sectional Chart it describes this airspace.

• Oh wow! Thanks, I did not see that at all. Can you explain where they got 1200 AGL from? Commented Oct 3, 2018 at 22:16

• Thanks! I'll be sure to remember this for my test in the next couple of days. Commented Oct 3, 2018 at 22:27
• @Crazydaze Since you are studying for the test, you also need to know that: “A Federal airway includes the airspace within parallel boundary lines 4 NM to each side of the centerline.” Commented Oct 4, 2018 at 4:01
• @JScarry - good comment above, but it's important to ensure that the questioner knows that in the entire area (not just the 4nm to either side of V15 ) Class E [controlled airspace] exists and begins at 1200' AGL. The exception, as shown on the map excerpt, are the areas to the west of V15 that are surrounded in magenta color depicting Class E [controlled airspace] beginning at 700' AGL.
