Flying an A-10 before INS was a real challenge. . .1:250 maps required a real map reading/navigating skill and an ability to fold and “juggle” the maps. . .let alone if your flight profile took you from one map to another. . .
The Denver sectional is a mess. We are smack dab in the middle of three sectionals (Denver, Wichita, and Cheyenne), a Class B and C, and a multitude of Ds, not to mention a dozen restricted airspaces to watch out for. Map reading is a fun skill to keep alive.
P.S. Not to mention the Cumulogranite clouds to the west.
