Chapter 7: Instrument Navigation

CHAPTER SEVEN

INSTRUMENT NAVIGATION

700.

INTRODUCTION

In this block of instrument training, you will build upon what you learned in earlier RI training

blocks and introduce a few new concepts and procedures. Emphasis will be placed upon

operations in the actual IFR environment.

Be ready for deviations from the ATC controller. You may be required to operate "outofthe

norm" from the way you did things in earlier training. Examples of variations that may require

adjustments on your part are:

"Maintain 150 knots until the FAF."

"Reduce to your final approach speed."

Expect frequency changes at the worst possible time. Remember to AVIATE, NAVIGATE,

and COMMUNICATE.

Unexpected holding instructions.

Assigned altitude restrictions even though you are cleared for the approach.

Compute your actual ground speed from the FAF to the MAP based on the latest wind

information.

The bottom line is listen closely to the radios and be ready for anything. You must know your

procedures, but be ready to modify them as the situation dictates.

To the maximum extent possible, instrument flights will be flown using actual approaches to

"real" airports during this block of training. When in actual instrument conditions you may be

flying without the instrument hood. This can be quite disorienting when transitioning in and out

of cloud layers. You must be able to apply proper Instrument procedures while maintaining good

basic airwork.

You will become quite familiar with Base Ops and Weather. You will be required to complete a

DD 175 flight plan, put it in the ATC system, and then go fly it. You should brush up on filling

out flight plans with the help of FLIP, General Planning (GP).

You will also obtain DD 1751 weather briefs. Dust off those old Meteorology pubs and review

such things as Terminal Area Forecasts, Radar Summaries, Winds Aloft, etc. Also, review

weather requirements for destination and alternates.

Be sure you have a solid foundation to build upon. Review all RI Procedures and eliminate any

questions and "gray areas." Strive for a clearer understanding of the "Big Picture."
