Narrative:

VFR takeoff, climbing 1400-2000'. CTAF 121.30 (monitoring). X:30 am, runway 14. After takeoff at mtn, CTAF cleared me for a right turn on course to bwi. My passenger (air carrier pilot )called out traffic approximately 300' below us on downwind for runway 14 at martin state. The course of that aircraft and ours were perpendicular (see exhibit below). No advisory. This happens because the restr areas R4001A & B restrict northeast arrs, and thus, as shown below, they have to cross the takeoff corridor during a south operation (runway 14). Then, when turning downwind, arrival aircraft conflict with southwest departures. Recommendations: establish FAA tower with separate sector for approach control, published arrival/departure rtes, clearance delivery, more pay for CTAF controllers to improve morale, and BRITE scope.

Title: ACFT MADE A RIGHT TURN AFTER TKOF AND PASSED OVER AN ACFT ENTERING DOWNWIND AT AN UNCONTROLLED ARPT.

Narrative: VFR TKOF, CLBING 1400-2000'. CTAF 121.30 (MONITORING). X:30 AM, RWY 14. AFTER TKOF AT MTN, CTAF CLRED ME FOR A RIGHT TURN ON COURSE TO BWI. MY PAX (ACR PLT )CALLED OUT TFC APPROX 300' BELOW US ON DOWNWIND FOR RWY 14 AT MARTIN STATE. THE COURSE OF THAT ACFT AND OURS WERE PERPENDICULAR (SEE EXHIBIT BELOW). NO ADVISORY. THIS HAPPENS BECAUSE THE RESTR AREAS R4001A & B RESTRICT NE ARRS, AND THUS, AS SHOWN BELOW, THEY HAVE TO CROSS THE TKOF CORRIDOR DURING A S OPERATION (RWY 14). THEN, WHEN TURNING DOWNWIND, ARR ACFT CONFLICT WITH SW DEPS. RECOMMENDATIONS: ESTABLISH FAA TWR WITH SEPARATE SECTOR FOR APCH CTL, PUBLISHED ARR/DEP RTES, CLRNC DELIVERY, MORE PAY FOR CTAF CTLRS TO IMPROVE MORALE, AND BRITE SCOPE.
