Instrument approaches
Lesson plan revised 8 March 2010; instrument theory.
Objective
The student should leave with an understanding of DME operation and the instrument landing system and be able to apply that knowledge to flight scenarios.
Elements
- tracking navaids – review
- working with ATC – review
- approach briefing – review
- procedure turn – review
- minimum altitudes: MDA & DA
- visual maneuvering – review
- missed approach
- holding – review

| Total | 1 hour 15 minutes |
Equipment
- pen and paper
- Instrument Flying Handbook and The Pilot’s Manual: Instrument Flying
- instrument procedure charts
- laptop with flight simulator and internet access
Online resources
- Tim’s Navigation Simulator works with multiple technologies
- Selkirk IFR trainers
- AIM Chapter 1: Air Navigation
Instructor actions
- Introduce and motivate with the question of how we gauge distance and arrive at the airport without visual references
- Describe new navigation systems and their operation in a predominantly lecture format
- Illustrate techniques using Tim’s simulator
- Review each system before moving on to the next
- Evaluate student knowledge with questions emphasizing understanding rather than rote
- Have the student solve multiple scenarios
- Conclude with an oral quiz, identifying and correcting errors
Student actions
- Arrive with completed homework assignment
- Maintain active involvement by responding to questions and taking notes
- Guide the instructor through the intercepting and tracking of several simulator scenarios
- Complete an oral quiz and demonstration of the concepts
Completion standards
The lesson will be complete when the student can describe DME and ILS equipment – and demonstrate an understanding of the techniques required to smoothly and accurately intercept and track a localizer and glideslope – with minimal instructor guidance.
Teaching outline
Review radio principles
- What are the three types of waves?
- Which kind of frequency does the ILS use? How about DME?
CDI with localizer and glideslope
- Not all CDIs can be used with an ILS, but all should work with a localizer
- when flying a localizer, it is four times as sensitive – every dot is .5° rather than 2°
- the glideslope needle will be flown just like a normal lateral course – the center is the airplane
- performance instrument, used as a reference to adjust control inputs
Instrument Landing System, IF 309 & IFH 7-27
The ILS is a precision approach, providing both lateral and vertical guidance down a predetermined flight path.
