5-5-14. Instrument Departures

a. Pilot.

1. Prior to departure considers the type of terrain
and other obstructions on or in the vicinity of the
departure airport.
2. Determines if obstruction avoidance can be
maintained visually or that the departure procedure
should be followed.

3. Determines whether an obstacle departure

procedure (ODP) and/or DP is available for
obstruction avoidance. One option may be a Visual

Climb Over Airport (VCOA). Pilots must advise
ATC as early as possible of the intent to fly the VCOA
prior to departure.

4. At airports where IAPs have not been
published, hence no published departure procedure,
determines what action will be necessary and takes
such action that will assure a safe departure.

b. Controller.

1. At locations with airport traffic control

service, when necessary, specifies direction of

takeoff, turn, or initial heading to be flown after


2. At locations without airport traffic control
service but within Class E surface area when
necessary to specify direction of takeoff, turn, or
initial heading to be flown, obtains pilot's concur-
rence that the procedure will allow the pilot to comply
with local traffic patterns, terrain, and obstruction
3. Includes established departure procedures as
part of the ATC clearance when pilot compliance is
necessary to ensure separation.

5-5-15. Minimum Fuel Advisory

a. Pilot.

1. Advise ATC of your minimum fuel status
when your fuel supply has reached a state where,
upon reaching destination, you cannot accept any
undue delay.

2. Be aware this is not an emergency situation,
but merely an advisory that indicates an emergency
situation is possible should any undue delay occur.

3. On initial contact the term "minimum fuel"
should be used after stating call sign.

Salt Lake Approach, United 621, "minimum fuel."
4. Be aware a minimum fuel advisory does not
imply a need for traffic priority.
5. If the remaining usable fuel supply suggests
the need for traffic priority to ensure a safe landing,
you should declare an emergency due to low fuel and
report fuel remaining in minutes.

Pilot/Controller Glossary Term- Fuel Remaining.

b. Controller.

1. When an aircraft declares a state of minimum
fuel, relay this information to the facility to whom
control jurisdiction is transferred.

2. Be alert for any occurrence which might
delay the aircraft.

5-5-16. RNAV and RNP Operations

a. Pilot.

1. If unable to comply with the requirements of

an RNAV or RNP procedure, pilots must advise air

traffic control as soon as possible. For example,

"N1234, failure of GPS system, unable RNAV,
request amended clearance."
2. Pilots are not authorized to fly a published
RNAV or RNP procedure (instrument approach,
departure, or arrival procedure) unless it is retrievable
by the procedure name from the current aircraft
navigation database and conforms to the charted
procedure. The system must be able to retrieve the
procedure by name from the aircraft navigation
database, not just as a manually entered series of
3. Whenever possible, RNAV routes (Q- or
T-route) should be extracted from the database in

their entirety, rather than loading RNAV route
waypoints from the database into the flight plan
individually. However, selecting and inserting
individual, named fixes from the database is
permitted, provided all fixes along the published
route to be flown are inserted.

4. Pilots must not change any database
waypoint type from a fly-by to fly-over, or vice
versa. No other modification of database waypoints
or the creation of user-defined waypoints on
