Prepare and tabulate the necessary field note data for laying out the reversed curve by deflection angle method. The deflection angle from the back tangent of the points on the curve from PC to PRC. The deflection angle from the common tangent of the point on the curve from PRC to PT. 2. In the field choose point PC on the ground. Layout the Pl of the first simple curve 3. Set-up the transit at PC. Set zero on Vernier A. Sight at the Pl of the first simple curve. 4 Layout the simple curve from PC to PRC by deflection angle from the back tangent 5. Transfer the transit at the PRC. Back sight at PC with the transit telescope reversed. 6. Plunge the transit telescope to normal and read on Vernier A the deflection angle of PRC from the back tangent (l2). The line of sight now is the common tangent of the reversed curve 7. Layout the simple curve from the PRC to PT by deflection angle reckoned from the common tangent. &. Check the positioning of the PT as in the previous field works.
