1. Runway 5-23 Obstruction and Visibility Minimums Update
Morristown Aviation Association
August 2, 2017

2. Previous Airport Obstruction Mapping
History
Previous Airport Obstruction Mapping
Aeronautical survey completed in October 2008 and utilized as part of Master Plan Update
Completed at the infancy of FAA Airports GIS Requirements for aeronautical surveys
Limited use commenced in FAA Fiscal Year 2007
FAA AGIS aeronautical surveys are more detailed and inclusive than previous methodologies

3. New Aeronautical Survey
History
New Aeronautical Survey
Completed in June 2016 and approved by FAA/NGS in March 2017
Captured growth in trees off the approaches to all runways
FAA has been increasing scrutiny of approach procedures nationally, leading to changes in approach procedures at MMU

4. FAA Others Constraints Tree removal limited to November-March
Differing information from different offices has led to confusion and incorrect information provided
Actions have been taken prior to informing the Airport
FAA funding eligibility is limited to the one-time removal of trees/vegetation on an area
Others
Tree removal limited to November-March
NJDEP GP-9 provisions
Ownership Status

5. 20:1 Surface (TERPS) MALSR Line-of-Sight Recent FAA Emphasis
In 2013, FAA increased enforcement of penetrations to the TERPS 20:1 Visual Approach Surface
Preclude use of instrument approach procedures at night
Continuous assessment of approaches
MALSR Line-of-Sight
Winter 2017 – FAA requires prompt removal of MALSR line of sight obstructions

6. Glidepath Qualification Surface (GQS)
Recent FAA Emphasis
Glidepath Qualification Surface (GQS)
May FAA increased enforcement of penetrations to the GQS, a 30:1 surface the enables use of vertically-guided approach procedures
Penetrations must be removed or procedure will be NA
Obstructions removed on Runway 23 to enable continued use of ILS & LPV
Required special permission from NJDEP and USFWS

7. Upcoming Changes

8. Glidepath Qualification Surface (GQS)
RW 5 GQS Penetrations
Glidepath Qualification Surface (GQS)
Runway 5 Obstructions to GQS are off-airport
2008 Obstruction Study noted a GPA of 3.6° was necessary to avoid water tower
Vegetation currently would obstruct a GPA of 3.6°
Current Glide Path Angle (GPA) of 3.5° published despite known penetration by water tower and trees.
Implementation of existing approach was coordinated outside normal procedures

9. RW 5 GQS Penetrations

10. Glidepath Qualification Surface (GQS)
RW 5 GQS Penetrations
Glidepath Qualification Surface (GQS)
Anticipate changes to Approach Procedures
LPV & LNAV/VNAV procedures are NA
LNAV and Circling will remain unchanged
Reviewing increase in GPA to mitigate obstructions
A minimum of 3.7° is anticipated
A GPA of up to 3.77° is acceptable for aircraft with approach speeds of up to 141 knots (as of 10/1/17)
Developing plan for removal of vegetation
Water tower will preclude reduction of GPA below 3.6°

11. RW 23 Final & Missed Penetrations
Runway 23 Approach Minimums
On 8/1/17, FAA published NOTAM increasing HAT for LPV and ILS from 200’ to 305’
FAA identified obstructions to the Final Approach and Missed Approach Surfaces
MMU has commenced removal of obstructions, and will complete remaining effort in Fall/Winter 2017
Obstruction removal in 2017 will enable reduction of HAT to 250’ for LPV and ILS

12. RW 23 Final & Missed Penetrations

13. RW 23 Final & Missed Penetrations
Runway 23 Approach Minimums
Obstruction removal in 2017 will enable reduction of HAT to 250’ for LPV and ILS
MMU working to obtain approvals to remove remaining trees, enabling reduction in HAT to 200’ for LPV and ILS

14. Continue Coordination with FAA
Next Steps
Continue Coordination with FAA
Provide up to date information on removed obstructions
Coordination on increase in GPA for RW 5
Continue monitoring of vegetation and removal prior to growth and identification as an obstruction
