Instrument Flight Planning
TAKE OFF MINIMUMS
Special Instrument Rating
1. No takeoff ceiling or visibility limits apply.
2. Takeoff dependent upon judgment of pilot and urgency of flight.
Standard Instrument Rating
1. Lowest non-precision minimums for runway in use but not lower than 300-1.
2. If runway has a precision approach, takeoff is permitted to precision minimums or 200-1/2,
whichever is higher.
Use the STANDARD T-45A FUEL PLANNING DATA chart (Figure 13) to determine your fuel
requirements for a flight.
OPNAVINST 3710.7 and CNATRA cross-country instructions set policy for minimum fuel requirements.
Local directives may impose further fuel requirements for your cross-country flights, and the situation may
dictate that you need to plan for more reserve fuel than the minimum required in the event of higher winds,
worse weather, increased distance to a suitable alternate, or other unusual circumstances.
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 pilots responsibility to complete the
briefing form for telephonic or weathervision 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.
