INSTRUMENT FLIGHT RULES

400. INTRODUCTION

This chapter introduces the student to OPNAVINST 3710.7 criteria for VFR and IFR flight, to

include filing requirements, weather for alternation selection, take-off weather requirements, and

instrument approach requirements. Filling out the DD 175 Military Flight Plan using GP chapter

four is explained.

401. LESSON TOPIC LEARNING OBJECTIVES

TERMINAL OBJECTIVE

4.0 The student will demonstrate an understanding of weather criteria for filing purposes, and

the ability to complete a DD 175 Military Flight Plan.

ENABLING OBJECTIVES

flight.

4.1.1

State the minimum ceiling and visibility for VFR flight in controlled areas.

4.1.2

State cloud clearance requirements for VFR flight.

4.2 Determine when Instrument Flight Rules (IFR) must be used by Navy/Marine Corps pilots

for flight.

standard and special instrument rated Navy/Marine pilots.

4.3.1

State the weather minimums for takeoff for special instrument rated pilots.

4.3.2

State the basic weather minimums for takeoff for standard instrument rated pilots

and the exceptions.

4.4 Determine when the destination weather meets the minimum weather requirements for that

type of IFR approach the pilot plans to execute.

4.5 Determine when an alternate airport is required.

4.6. State where Navy/Marine Corps alternate airport weather requirements are listed.

4.7 Determine when the alternate airport must be forecasting weather to be 3000/3 or better.

4.8 Determine how to select an alternate airport which meets the forecast weather requirements

as the alternate.
