training specific missions. A training mission may be considered ‗operational‘ if external
users (e.g. cargo load training, JA/ATT, etc.) are scheduled as part of the training
mission.
6.16.3.4.1. Special Departure Procedure. SDPs are MDS-specific OEI escape
procedures intended only for emergency use when operationally necessary. They are
applicable after the loss of an engine and, where available, will be used for engine-out
departure planning. Retrieve current SDPs from the SDP website (contact OGV for
current username password). ‗Ad hoc‘ requests for fields not currently listed may be
requested through OGV NLT 48 hrs prior to scheduled departure. MAJCOM/A3V
authorizes the use of Ad Hoc SDPs for a maximum of 7 days after the analysis date.
6.16.3.4.2. Minimum climb gradient. The TERPS standard minimum climb gradient
is 200 ft/nm, which is based on the standard obstacle clearance surface (OCS) of 152
ft/nm plus the required obstacle clearance (ROC) of 48 ft/nm. If an SDP is not
available, the crew must ensure compliance with any obstacle-based minimum climb
gradients for the selected departure, with one-engine inoperative. Minimum climb
gradients may be published as a ‗Trouble T‘ restriction in the IFR Take-off
Minimums section of FLIP or on a SID. When required for mission accomplishment,
the operations supervisor (or equivalent mission execution authority supervisor) may
authorize the PIC to ensure the aircraft vertically clears all obstacles along the
planned departure path OEI by subtracting up to 48‘/NM from the published (or
standard) climb gradient or the use of the departure runway‘s SDP for OEI departure
planning. For training missions the operations supervisor is the OG/CC or equivalent,
delegated no lower than the Sq/DO. As execution authority on all 618 AOC (TACC)
tasked missions, the 18 AF/CC has authorized the PIC to subtract the 48‘/NM.
Minimum climb gradients do not take into account low, close in obstacles (obstacles
that require a climb gradient to an altitude of 200‘ or less above departure end of
runway elevation) which should normally be published as a NOTE on the SID or IFR
departure procedure (Trouble T). Crews must also ensure the aircraft can clear these
obstacles. NOTE: If OEI obstacle clearance cannot be satisfied by one of the above
methods, download cargo/fuel or delay until more favorable conditions exist.
6.16.4. Critical Field Length (CFL). Takeoff GW must never exceed that which would
require CFL in excess of the runway available for a normal takeoff. In some cases, a
minimum altitude is required at the published screen height.
6.16.5. Gross Weight (GW). Ensure that the aircraft does not exceed the maximum GW,
zero fuel weight, or center of gravity limitations specified in the aircraft flight manual. GW
may be further restricted by operating conditions such as, icing, temperature, pressure
altitude, runway length and slope, aerodrome weight bearing capacity, departure
maneuvering, required climb gradients, and obstacles.
6.16.5.1. Takeoff GW must not exceed that which would, in the event of an engine
failure, lower the rate of climb to less than a 2.5 percent climb gradient (152-feet per
NM).
6.17. Weather Minimums for Takeoff. Use Table 6.3.
