These obstacle notes will no longer be published on
SIDs. Pilots assigned a SID for departure must refer
to the airport entry in the TPP to obtain information
on these obstacles.
(b) The purpose of noting obstacles in the
"Take-off Minimums and (OBSTACLE) Departure
Procedures" section of the TPP is to identify the
obstacle(s) and alert the pilot to the height and
location of the obstacle(s) so they can be avoided.

This can be accomplished in a variety of ways; for
example, the pilot may be able to see the obstruction
and maneuver around the obstacle(s) if necessary;
early liftoff/climb performance may allow the
aircraft to cross well above the obstacle(s); or if the
obstacle(s) cannot be visually acquired during
departure, preflight planning should take into account
what turns or other maneuvers may be necessary
immediately after takeoff to avoid the obstruction(s).

FIG 5-2-1

Diverse Departure Obstacle Assessment to 25/46 NM

EXAMPLE-

TAKEOFF OBSTACLE NOTES: Rwy 14, trees 2011"
from DER, 29" left of centerline, 100" AGL/3829"
MSL. Rwy 32, trees 1009" from DER, 697" left of
centerline, 100" AGL/3839" MSL. Tower 4448" from
DER, 1036" left of centerline, 165" AGL/3886" MSL.
NOTE-
Compliance with 14 CFR Part 121 or 135 one-engine-inoperative (OEI) departure performance requirements, or
similar ICAO/State rules, cannot be assured by the sole use
of "low, close-in" obstacle dats published in the TPP.
Operators should refer to precise data sources (for
example, GIS database, etc.) specifically intended for OEI
departure planning for those operations.

5. Climb gradients greater than 200 FPNM are
specified when required to support procedure design
constraints, obstacle clearance, and/or airspace
restrictions. Compliance with a climb gradient for
these purposes is mandatory when the procedure is
part of the ATC clearance, unless increased takeoff
minimums are provided and weather conditions
allow compliance with these minimums.

5-2-8

NOTE-
Climb gradients for ATC purposes are being phased out on
SIDs.
EXAMPLE-
"Cross ALPHA intersection at or below 4000; maintain
6000." The pilot climbs at least 200 FPNM to 6000. If 4000
is reached before ALPHA, the pilot levels off at 4000 until
passing ALPHA; then immediately resumes at least 200
FPNM climb.
EXAMPLE-
"TAKEOFF MINIMUMS: RWY 27, Standard with a
minimum climb of 280" per NM to 2500." A climb of at least
280 FPNM is required to 2500 and is mandatory when the
departure procedure is included in the ATC clearance.
NOTE-
Some SIDs still retain labeled "ATC" climb gradients
published or have climb gradients that are established to
meet a published altitude restriction that is not required for
obstacle clearance or procedure design criteria. These
procedures will be revised in the course of the normal
procedure amendment process.
