not be used to compute a required climb gradient. There could be other
significant obstacles at lower altitude, closer to the DER. Non-standard takeoff
weather minimums only represent the controlling obstacle. This information also
does not tell the crew what the obstacle is or precisely where it is.
Figure 9.7. Non-Standard Weather Minimums.
9.7.2. Minimum Climb Gradient. The TERPS specialist may also provide a minimum
climb gradient for use with the FAAs “standard” takeoff weather minimums. This is the
type of IFR departure procedure most commonly used by USAF aircraft. Typically, the
non-standard takeoff weather minimums will have an asterisk (*) leading you to a note
which will say something like, “Or standard with minimum climb gradient of 300 ft/NM
to 700 feet.” USAF aircraft are authorized to depart IFR using the minimum climb
gradient. When using this type of IFR departure, substitute your MAJCOM-directed
takeoff weather minimums in place of the word “standard.” USAF aircraft must always
meet or exceed the published climb gradient with all engines operating for the runway
used.
Figure 9.8. Climb Gradient In Lieu of Non-Standard Weather Minimums.
9.7.3. Specific Routing. A third method used by the TERPS specialist is to provide a
specific route of flight, which will take the aircraft away from the obstacle. You must be
careful when using this type of IFR departure. Make sure no requirement exists to use
non-standard takeoff weather minimums in order to execute the procedure. This situation
could indicate more than one obstacle along the departure path and would not be allowed
unless you comply with paragraph 9.7.1.1.
Figure 9.9. Obstacle Departure Procedure (ODP).
9.7.4. Combination of All Three Methods. Some IFR Departure Procedures use a
combination of all three methods. Make sure that if the procedure requires the use of
non-standard takeoff weather minimums, the aircraft performance with one engine
inoperative will allow the aircraft to be at the non-standard ceiling minimum by the end
of the runway.
