the VOR approach. If I were cleared for a localizer approach, I’d cross the outer marker at 1,900 feet
(position J) then descend to 560 feet (position K) and fly to the MAP. The MAP is identified by time
(based on a specific ground speed from the outer marker) or by DME on the localizer as shown by
position L.
Most everything else about this approach chart should now be familiar to you. For example, suppose
you’re over Battle Ground VOR (position M) and ATC clears you for the approach. The feeder route
from BTG to the ILS is the 135-degree radial (position N). Set your VOR to track outbound on this
radial until you intercept the localizer. How will you know that you’ve intercepted the localizer? You
can set one navigation radio (the bottom one) to navigate from BTG VOR and the other navigation
radio (the top one) to receive the localizer. As you track from BTG VOR, you’ll know you’re over the
localizer when the localizer needle centers. The outer marker beacon display will also activate in the
cockpit as an additional clue since the 135-degree course takes you to LAKER intersection (located
on the localizer).
At LAKER, fly 099 degrees (position O), descend to 3,500 feet (position P) and make a procedure
turn within 10 nm of LAKER. There is one important item you must know about localizers. Because
the localizer is a single electronic beam, tracking opposite its inbound direction results in the needle
appearing to read in reverse. In other words, when you are flying outbound from the localizer, if the
localizer needle moves in one direction (right or left) you must fly in the opposite direction (left or
right, respectively) to center it. This is known as reverse sensing. Therefore, as you prepare to fly the
procedure turn by tracking outbound on the localizer, you’ll have to fly opposite the direction of
needle swing to keep it centered.
Once you’ve completed the procedure turn and are inbound headed 279 degrees, the needle will
indicate normally. You may descend to 3,000 feet (the glideslope intercept altitude) once established
inbound on the localizer after making the procedure turn. Track the localizer and fly the glideslope
down to DA.
Why don’t you give this approach a try? Choose Tutorial 15, Situation 5.
The simulation places you at 3,000 feet on the localizer approximately 17.8 miles from the airport.
Assume that ATC has cleared you for the approach. This means you should track the localizer and,
when the glideslope needle centers, reduce power and begin a descent at 100 knots at
approximately 539 feet per minute. You can do it.
Press P to begin the simulation and P again to pause the simulation after you’ve landed. Of course if
you land too hard, the runway will pause the simulation for you, so be careful. And, if you want to try
one under actual instrument conditions with ½ mile visibility, choose Tutorial 15, Situation 6.
I think you should also try an approach from over Battle Ground VOR: choose Tutorial 15, Situation
7. The simulation places you at Battle Ground VOR, heading 135 degrees at 4,500 feet. Your NAV 1
radio is tuned to the localizer frequency (111.3 MHz) and NAV 2 is tuned to BTG VOR (116.6 MHz).
