5. The initial cruising true airspeed is entered next. If the pilot intends to change airspeed on
subsequent legs of the flight, he must notify ATC while airborne. This entry is not required on
VFR local flights.
In the POINT OF DEPARTURE box, the pilot should enter the location identifier of the
airport from which he is leaving. The location identifier is found in the IFR Enroute Supplement
and in the Terminal Publications (Approach Plates). If the identifier has four letters, do not use
the letter "K" on the DD 175. For domestic flights, use the last three letters of the identifier.
"KNPA" will be entered as "NPA." (Four letter identifiers are to be used on International Flight
Plans.) Use the airport name only if the airport has no location identifier.
7. The pilot should enter the proposed departure time using coordinated universal time (Z).
Time zone conversion/factors for all airports can be found in the IFR Supplement.
The next entry will be the altitude/flight level requested for the first leg of the flight. Enter
the initial requested altitude in hundreds of feet (120).
When filing an IFR flight plan, a pilot can request one of four types of instrument
departures. The four types are DEPARTURE PROCEDURES (DP), RADAR DEPARTURE,
IFR CLIMB (DIRECT TO NAVAID), and VFR DEPARTURE. If a pilot elects to use a DP, the
DP's coded identifier or the name and number of the DP plus the "termination point" or
"published transitional fix" will be entered as the first items in the ROUTE OF FLIGHT section.
A pilot filing a flight plan requesting CLIOS ONE departure with a transition point of CLIOS
would write the entry as follows (these DPs are referred to as SIDs in the (GP) General
