POFZ IntroductionPOFZ Introduction

POFZ protects the area of short final area during very low ceilings (<250’ feet) and or visibilities (<3/4 Sm or < 4000’ RVR)

POFZ ApplicabilityPOFZ Applicability

The requirement to clear the POFZ applies when an aircraft on a vertically guided final approach is within 2 nautical miles of the runway threshold and the reported ceiling is below 250 feet and/or visibility less than ¾ SM (or runway visual range below 4,000 feet).

The requirement to clear the POFZ applies when an aircraft on a vertically guided final approach is within 2 nautical miles of the runway threshold and the reported ceiling is below 250 feet and/or visibility less than ¾ SM (or runway visual range below 4,000 feet).



POFZ Applicability (Cont’d)POFZ Applicability (Cont’d)

The POFZ is considered clear even if the wing of the aircraft holding on a taxiway waiting for runway clearance penetrates the POFZ; however, neither the fuselage nor the tail may infringe on the POFZ.

If the POFZ is not clear, the MINIMUM authorized height above touchdown (HAT) and visibility is 250 feet and ¾ statute mile (SM).

POFZ CompliancePOFZ Compliance

• In the approved AOSC Decision Document #01, the requirement was set for the POFZ guidance to be applied uniformly to all airports nationally by January 1, 2007

• It was further noted that “any airport that fails to meet the POFZ guidance by that date will not have its procedures approved at their next subsequent biennial review”.

ARC-1 Memo to RAPTs (12/16/05)ARC-1 Memo to RAPTs (12/16/05)

• Less than a year remains before the POFZ implementation deadline

critical to successful implementation– Regional Airspace Procedures Team

(RAPT) support is needed

ARC-1 Memo to RAPTs (12/16/05) Cont.ARC-1 Memo to RAPTs (12/16/05) Cont.• Specifically, the AOSC requested (by February 28, 2006)

the RAPT to:

– Review the requirements outlined in AOSC Decision Document #01 (attached) to keep the POFZ clear under the specified conditions and determine the appropriate method of compliance for each runway end with a current or near-term planned precision approach.

– Identify the locations where additional markings/signage are needed and a target date for completion

• Follow-up by the RAPT toward the end of 2006 may also be needed to ensure that the necessary actions are completed by the January 1, 2007 deadline.

Frequently Asked QuestionsFrequently Asked Questions

• Does POFZ apply to GPS WAAS approaches?– The POFZ applies to any approach with ceiling

below 250 feet and/or visibility below 3/4 of a statute mile or below 4,000 RVR.

• Does POFZ apply at military airports?– The POFZ applies at joint-use facilities.

• How do we determine the 250 foot ceiling requirement?– The reportable values from appropriate weather

sources should be used to determine ceiling height.

• Does POFZ apply to GPS WAAS approaches?– The POFZ applies to any approach with ceiling

below 250 feet and/or visibility below 3/4 of a statute mile or below 4,000 RVR.

• Does POFZ apply at military airports?– The POFZ applies at joint-use facilities.

• How do we determine the 250 foot ceiling requirement?– The reportable values from appropriate weather

sources should be used to determine ceiling height.




• How do we apply POFZ at non-towered airports or towers that have limited hours?– Pilots will be notified of POFZ requirements at all

airports (including non-towered airports) through the Aeronautical Information Manual (AIM). Hold lines should be placed at the most conservative location to protect both the POFZ and the ILS critical area. Pilots are required to understand and comply with these markings.

• Who will fund modifications to the airport environment (marking, signage, concrete)?– ARP, working with the sponsor, should be

developing funding plans for the necessary modifications. However any extensive work requiring multi-year funding should be reported though the RAPT to the AOSC.

• Can the implementation date be deferred?– Any requests for deferral will be considered at the

AOSC executive steering group level).– Every effort needs to be made to meet the

deadline and each RAPT should report implementation concerns as soon as possible.

• If an airport is not able to comply by 1/1/07, is it an option to increase the published minima to 250 feet and ¾ statute mile?– Yes, that is an option.

• Are vehicles allowed to penetrate the POFZ when the POFZ is active?– The POFZ should be protected from all obstacles.

The only exception is a wing of a taxiing aircraft. This can be enforced by a hold sign on a road or other agreement with the airport operator
