CHANGE OF ROUTE OR DESTINATION DIVERT
While enroute, a decision might be made to divert from the planned destination and proceed to
the planned alternate or to another airfield. A change of destination may be requested through
Center using the DRAFT format.
D - Destination
R - Route of flight
A - Altitude desired
F - Fuel on board in hours and minutes
T - Time required in hours and minutes to destination
The term "DRAFT" has no legitimate meaning outside the Naval
Air Training Command, and should not be used in communications
If Center is unable to accept the DRAFT, then a request must be made with a FSS using the
format found on the back of the IFR Supplement. If the destination airfield is changed with
Center using a DRAFT, it is very possible that Center will not notify a FSS and the original
destination will be expecting an arrival. After landing ensure the original destination airfield was
notified of the change.
There is no clearly defined point of transition between the enroute and terminal phases of a
flight. The terminal phase is generally thought of as consisting of those procedures associated
with the aircraft destination (or field for practice approaches during an enroute delay). The first
of these procedures is obtaining field information via an ATIS, if available.
On a typical RI event these procedures usually include obtaining field ATIS and approach
clearances, placing on file contingency clearances (DRAFT), TACAN holding, TACAN
approach, RADAR approach, and associated missed approach procedures.
The most expeditious recovery at a destination would obviously include an enroute descent
direct to the VFR traffic pattern (i.e. course rules at NPA). Such VFR procedures will not be
simulated in RI events. With IFR conditions simulated at the field and enroute to the field, the
most expeditious recovery would be an enroute descent with RADAR vectors to for a GCA
approach. The RI curriculum requires High Altitude Instrument Approach Procedures
(TACAN Approaches) in most cases.
