AIM 

3. 

When the initial heading will take the aircraft off an assigned procedure (for example, an RNAV SID with 

a published lateral path to a waypoint and crossing restrictions from the departure end of runway), the controller 

will assign an altitude to maintain with the initial heading. 

4. 

Includes established departure procedures as part of the ATC clearance when pilot compliance is 

necessary to ensure separation. 

5. 

At locations with both SIDs and DVAs, ATC will provide an amended departure clearance to cancel a 

previously assigned SID and subsequently utilize a DVA or vice versa. The amended clearance will be provided 

to the pilot in a timely manner so that the pilot may confirm adequate climb performance exists to determine if 
the amended clearance is acceptable, and brief the changes in advance of entering the runway. 

6. 

At locations with a DVA, ATC is not permitted to utilize a SID and DVA concurrently.

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. 

EXAMPLE

−

 

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. 

REFERENCE

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.

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 waypoints. 

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.
