Note the timing "FAF to MAP" information at the bottom of the aerodrome sketch. This table is
used to determine the time to the MAP from the FAF at various ground speeds. The pilot must
estimate ground speed. Example: With an approach speed of 120 knots and 15 knots of
headwind, groundspeed becomes 105 knots, with timing of 2:48 (Figure 645). Timing should
always be used, when available, as a back up on DME approaches in case the DME should fail.
New Approach Plate diagrams are replacing the existing plates (Figure 646). The
organization of the plates are basically the same. Missed Approach Procedures have moved to the
top lefthand side and a diagram has replaced the text in the profile view. The NAVAID and
radio frequencies and other pertinent information are labeled in blocks at the top to help the pilot
quickly locate them. Eventually all approach plates will be in this format.
