100
This chapter contains information that applies to the flight inspection of ILSs.
What is Chapter 6?
100
Paragraphs 3-30 and 3-60 pertain to this.
What are Airborne Measurements Reference Parameters?
100
The resultant of a correlation of facility and airborne parameters, wherein the measurement of these parameters are within specified tolerances.
What is a flight inspection reference?
100
This airborne measurement is the average course between one (1) nautical mile and the runway threshold.
What is (front) Course Localizer Alignment?
100
In preparation for a flight inspection, the system specialist must be most familiar with these.
What are the facility's reference values?
200
This is the current change of JO 6750.49A
What is Change 9?
200
As established by flight inspection but >/= 68 percent.
What is initial and/or operating tolerance for clearance monitor modulation level alarm of a Capture Effect Glide Slope?
200
Referring to Tables 6-8 through 6-13, the failure to record either of these measurements results in an improperly established flight inspection reference?
What are facility and airborne measurements?
200
When establishing a new course alignment reference, the Flight Inspection Data Work Sheet will, at a MINIMUM, have this number of additional line entries.
What is two (2)? (CW/CCW Course Shift derivations; assuming the airborne measurment was reported as "Centerline")
200
Pre-flight inspection checks must be done within this time frame.
What is 5 days preceding?
300
This chapter prescribes standards and tolerances and are usually printed on blue paper.
What is Chapter 3?
300
"</= 125% of normal SBO power."
What is Narrow Course Width Alarm initial and operating tolerances?
300
Any time a facility measurement is changed from the reference value, the airborne measurments must meet this.
What is Initial Tolerance?
300
With a carrier feedline of .000 ddm, I must now adjust to this after flight inspection reports the alignment at 4 microamps left.
What is .004 ddm/90 Hz?
300
The purpose of a monitor flight inspection is to verify this.
What are the limits of the radiated signal?
400
This Chapter presents technical characteristics and theory of operation for the ILS.
What is Chapter 2?
400
"0.75 to 0.87 degrees."
What is initial tolerance for Glide Slope Wide Alarm?
400
The proving of valid FI references through direct correlation of facility documentation and associated FI reports.
What is Traceability?
400
While being at reference of .001 ddm/90 Hz, I must adjust to this after flight inspection reports an alignment of 3L.
What is no adjustment necessary?
400
Do not depend of this to adjust the radiated parameters. In fact, it could even be shut off.
What is the monitor?
500
This team initiates, maintains, and is considered the "owner" of JO 6750.49A.
What is AJW-143, OR the Navigation & Landing Systems Team?
500
">/= 165 microamps"
What is initial tolerance for Normal Low Clearances?
500
Along with adjusting the monitor and establishing new TPRs, this must be performed at a localizer when the sideband power or carrier feedline references have changed.
What is a reference ground check?
500
With a carrier feedline of .001 ddm/90, I must now adjust to .004 ddm/150 Hz after hearing this announced alignment.
What is 5 microamps right?
500
When a reference value is establsihed during a given flight inspection, a copy of the associated flight inspection report and data worksheet(s) shall be retained until this time.
What is facility decommissioning?
