20:1 Penetrations Background
• Late 1990’s: Criteria developed by Flight Standards (AFS).
• Oct 2012: AFS required immediate NOTAM action to restrict night operations when 20:1 penetrations identified.
• Jan 2014: Refined policy considered “Risk” factors based on the amount of obstacle penetration, allowed the airport manager a 30 day validation period, and allowed for Category A/B and C/D surface areas to be restricted independently. (NOTAMs could restrict the C/D area only if the A/B area was clear of penetrations).

• AFS has implemented a change to FAA Order 8260.3B, United States Standards for TERPS, Straight-in Visual Area Beginning Width.
Recent Change to 20:1 Dimensions

How are 20:1 Approach PenetrationsIdentified ?????
•Biennial Review: Terminal instrument procedures reviewed every two years against current criteria. During this review 20:1 penetrations may be identified.
•Routine Amendments: While amending procedures to support airport improvement projects or Air Traffic change requests, current criteria is applied and 20:1 penetrations may be identified.

When 20:1 Penetrations Identified Notification Process
• Initial Notification: Within 3 business days, a file is forwarded to the airport sponsor requiring validation of each penetration ASAP, but not more than 30 days. The Airport District Office (ADO) is info copied.
• Action required by sponsor: Airport owner/sponsor must provide written validation report to FPT and info copy ADO.
• No Response: If no response received from sponsor within 30 days, the penetrations will be treated as existing and the instrument Approach Procedures (IAPs) will be restricted at night by NOTAM.

Obstacle Verification• Verification: Airport owner/sponsor must verify the
validity of each penetration as soon as possible but notification must not exceed 30 calendar days.
• 20:1 Determined Invalid: Sponsor determines the obstacle does not exist or it has been removed or reduced in height that no longer penetrates the 20:1 surface. (Documentation Required).
• 20:1 Determined Valid: Sponsor determines the obstacle does exist at the reported location/height.

Airport Owner/Sponsor Required Response
• If 20:1 penetrations determined INVALID: FPT will notify applicable offices to update airport’s data file(s). NOTAM action will not be taken to restrict or modify Instrument Approach Procedure (IAP).
• If 20 to 1 penetrations determined VALID: – Airport owner/sponsor submits written compliance plan.– Airport owner/sponsor mitigates the penetration through
removal, lighting, reduction in height, or VGSI waiver.– FAA action taken per Risk Assessment Criteria

Alternate Mitigation Option using Visual Glide Slope Indicator (VGSI):
• Temporary waiver good for 30 days while obtaining Flight Standards Approval.
• VGSI Mitigation Requirements: –Equipment Unrestricted & Clear OCS–Angle of VGSI equal to or less than IAP angle–TCH not more than 15 FT higher than IAP TCH–Visual Descent Point (VDP) not published–Visibility not lower than 1 SM.

Obstacles Mitigated – NOW WHAT???• Trees Removed: Notify FPT of tree removal. Include
Obstacle Identification (ID).
• Trees Trimmed: Notify FPT of completed tree trimming. A stamped and signed survey must be provided to support a new obstacle height. – Obstacle ID with Coordinates– Site Elevation with Accuracy Code (AC)– Revised Tree MSL and AGL Height
• Structures Lighted: Notify FPT if the structure has been lighted (Include the obstacle ID).

Re-Evaluation of Night Restrictions • Existing Night Restrictions: Contact FPT and ask for a
re-evaluation of your airport to determine if the new surface area provides any relief to your airport.
• NOTAMs: – If there are existing NOTAMs and it’s determined the
20:1 penetrations are no longer applicable or have been removed, the NOTAM can be cancelled
– If restrictions are already charted (NA at Night) and it’s determined the restriction is no longer applicable, it’s possible to regain night operations through a temporary NOTAM followed by a chart amendment.
