1、Instrument Approaches,ILS Approaches,-AIM 1-1-9 -IFH p. 7-28,FAA fig 96 some LDAs are equipped with a glide slope LDA width between 3o and 6o (like the ILS Localizer) 3-letter code with the “I” (two dots) used for the Localizer,ROSSLYN LDA RWY 19,Localizer Directional Aid (LDA),LDA,Note the Visual A

2、pproach Path,Simplified Directional Facility (SDF),Similar to ILS and LDA Localizer but less accurate Simplified directional facility No glide slope at all May be offset from runway centerline Where the ILS or LDA Localizer is typically between 3o and 6o , the SDF is fixed at either 6o or 12o 3-lett

3、er code without the “I” (two dots) used for the Localizer,MLS Approach,Typically a military facility. Requires sophisticated receivers not normally found on most aircraft. Displays on conventional ILS/VOR displays Provides precision navigation guidance in both azimuth and elevation. Has a wider appr

4、oach path than ILS (40o vs. 35o on either side of approach centerline). Has simultaneous voice communications capability.,Microwave Landing System Approach,MLS,MLS RWY 27,MLS Approach,Microwave landing system Precision approach Multiple final approach paths curved paths multiple glide slope angles B

5、ack azimuth possible for missed approach guidance and departure Identified by “M - ”,ILS Approaches to Parallel Runways,Divided into 3 classes based upon: 1) Runway centerline separation 2) ATC procedure and capabilities Pilot considerations: See situationally whats going on,Parallel ILS Approaches,

6、Simultaneous Close Parallel ILS Approach,4,300 apart due to the precision runway monitor (PRM) At least 1 second updates on each target High resolution color ATC display Audio and visual alert systems for controllers Software for projecting aircraft track vectors,Simultaneous ILS,ILS/DME RWY 34L - S

7、alt Lake City Small ILS feathered arrow means Independent which is 4,300,ILS RWY 25R Los Angeles See note Sidestep minimums,Simultaneous Converging Instrument Approach,Possible with runways 15 to 100 Criteria: MAPs at least 3 miles apart Missed approach procedures do not overlap All terminate with a straight-in Fly as normal DFW u
