NOTAMS
Notices to Airmen (NOTAMS) are your primary source of up-to-date information concerning the
establishment, condition, or change in any component (facility, service, procedure, or hazard) in the
National Airspace System. NOTAMS are available in several forms and are divided into various coverage
categories, depending on the location, nature, or duration of the notice. Prior to filing a flight plan, you
must check all applicable NOTAMS for your intended route, destination, and alternate.
FLIGHT PLANNING FORMS
You will use three forms to prepare for a cross-country flight: the weather briefing form (DD-175-1), the
Single-Engine Jet Log, and the Military Flight Plan (DD-175).
WEATHER BRIEFING (DD-175-1)
You are required to get a completed DD-175-1 for all IFR flights. For cross-country flights, you should
attend the weather brief in person prior to filing your flight plan. The forecaster shall complete the form for
briefings conducted in person and for autographic briefings. It is the pilot’s responsibility to complete the
briefing form for telephonic or weather vision briefings. It is important that you become familiar with all the
available charts and data available in the weather office so that you can have a complete picture of the
expected weather during the flight.
SINGLE-ENGINE JET LOG
The Single-Engine Jet Log is designed primarily to facilitate your fuel management. The front of the jet
log, when properly filled out, is a ready reference for your entire flight. Included on the jet log are
departure and destination information, clearance instructions, NAVAID, course, distance, time enroute,
fuel required for each leg, and data for a divert from the destination to your alternate.
MILITARY FLIGHT PLAN (DD-175)
After planning your flight, complete a DD-175 and file it with Base Operations at least 30 minutes prior to
your planned takeoff time (or as local directives require). The procedures and guidelines for completing
and filing a DD-175 can be found in FLIP General Planning and OPNAVINST 3710.7.
Stop-Over Flight Plan
When you are planning to land at one or more points prior to reaching your final destination, you may file a
stopover flight plan. You are responsible for updating your weather briefing (DD-175-1) and NOTAMS at
each stop.
Enroute Delay Flight Plan
If your planned flight includes an enroute delay, you must file an enroute delay flight plan. You would
commonly use this type of flight plan when performing instrument approaches at airports along the route
of flight or if you were to delay in a MOA.
