Atlantic Orientation Charts - AT(H/L) 1 & 2 - Introduction
These charts are used for route planning and en route navigation between major transatlantic aerodromes. Both charts are Lambert Conformal Conic Projections. The scale of the AT(H/L)1 is 1 inch = 132 NM; AT(H/L)2 is 1 inch = 136 NM.
AT(H/L) 1 & 2 - Distance Measurement
Distance is obtained by:
•Extracting the values which are printed parallel to the published tracks and/or sectors thereof.
•Using the nautical mile scale at the left and right-hand margins.
•Using the adjacent meridian scale.
AT(H/L) 1 & 2 Information
•The front panel shows:
•The coverage of the chart pictorially
•NAVAID LEGEND
•SELECTED VOLMET BROADCAST IN RADIO-TELEPHONY (RTF)
•Navaid information, listed alphabetically, is provided at Panel 1 AT(H/L)1 and panel 8 AT(H/L)2.
