Course

A classic mid-Atlantic VFR cross-country from the DC suburbs to the Jersey Shore. This route traverses some of the most complex airspace on the East Coast, threading between the Baltimore and Philadelphia Class B airspaces. It's an excellent training route for pilots building cross-country experience in busy airspace.

Advisory Only: This is an AI-generated advisory tool, not a certified flight planning service. Always verify data with official sources (1800wxbrief.com, ForeFlight, or FSS). The pilot in command is solely responsible for all go/no-go decisions.

Typical Weather

The mid-Atlantic region sees generally good VFR weather from April through October. Watch for afternoon convective activity in summer, particularly July and August. Winter brings lower ceilings and occasional IFR conditions. Spring and fall offer the best combination of clear skies and manageable winds. Sea breezes near the Jersey Shore can shift winds 20-30 degrees from the prevailing direction in the afternoon.

Airspace Notes

This route starts inside the DC Special Flight Rules Area (SFRA), requiring a filed SFRA flight plan and discrete transponder code before engine start. After departing KGAI, you'll pass beneath the BWI Class B shelf (floor 3,500 MSL). The middle segment crosses open Class E airspace over Delaware. As you approach from the west, you'll need to avoid or obtain clearance through the Philadelphia Class B. The route terminates at KBLM's Class D airspace, which is active when the tower is staffed (0700-2100 local).

Pilot Tips

  • 1File your SFRA flight plan at least 30 minutes before departure via 1800wxbrief.com
  • 2Plan to cruise at 3,000 MSL through the BWI transition to stay below the Class B shelf
  • 3Use the Delaware Memorial Bridge as a prominent visual checkpoint
  • 4Route east through the South Jersey corridor to avoid the PHL Class B
  • 5Contact Monmouth Tower on 126.7 about 15nm out for the Class D
  • 6If arriving after tower closure (2100L), use CTAF on 126.7
  • 7Carry approach plates for PHL-area airports as emergency diverts
