Figure 9.15. Civil SID.
chart with a “100 knot” groundspeed block, you can take the feet per
minute value in the “100 knot” column and divide it by 100 to calculate
the required climb gradient in percent gradient. For example, if the climb
rate in the “100 knot” column is 600 feet per minute, then divide by 100 to
convert the climb rate to percent gradient. In this case, 600 feet per
minute equates to a 6% climb gradient. To convert to feet per nautical
mile, multiply by 60 to determine the required climb gradient in feet per
nautical mile. In this case, the answer is 360 feet per nautical mile.
9.8.4.1.2. Civil SIDs. Although civil SIDs (FAA and CONUS Army procedures)
in the United States are constructed using the same TERPS criteria as military
SIDs, the information presented is significantly different. It is important to be
aware of the differences.
9.8.4.1.2.1. No Obstacles Are Identified or Depicted. Although many
obstacles may be present, civil SIDs do not provide any obstacle information
to the pilot.
9.8.4.1.2.2. ATC Climb Gradients. Civil SIDs also do not normally identify
ATC climb gradients in any way; it is up to the pilot to recognize and compute
any ATC climb gradients.
