## PARTICIPATING AIRPORTS

**PARTICIPATING AIRPORTS**

**Officials at airports operating under FAR Part 107 and Part 139 subject to icing weather conditions with control towers should develop LADPs in order to involve all interested parties in the deicing/anti-icing process.  Aircraft departing from airports without a LADP **_***are not exempt***_** from any traffic management initiative.**

_***NOTE:***_***  The old list of 29 airports identified by The Associate Administrator for Airports (ARP-1) has been eliminated!***

## The operators of these airports have been requested to host meetings involving airport users and AT in a partnership effort to achieve common solutions to local aircraft ground deicing/anti-icing problems. The emphasis is on developing local strategies that minimize the amount of time an aircraft spends on the ground after being deiced/anti-iced.

**AT managers who receive requests from airport operators to participate in these meetings will use the following guidance: **

**1. When requested by the airport operator, the AT manager shall participate in the development of an LADP.  Since **_***a LADP plan can effect an airport acceptance rate***_*** ***_***and/or departure rate***_**, the AT manager shall include the participation of the AT manager from the appropriate ARTCC, who shall participate and/or utilize their traffic management unit (TMU).  The plan will be reviewed and updated annually.  The plan shall include: **

**(a)  A clear definition of triggering mechanism(s) used to implement the LADP, e.g. holdover tables, visible precipitation. **

**(b)  Assignment of responsibility to notify AT of implementation and cessation of the LADP. **

## NOTE-Air traffic facilities should not become the triggering mechanism except in rare circumstances.  If AT is designated as the triggering mechanism, submit the proposed LADP to the ATD for approval.

**2. Develop or enhance local strategies to manage the number of aircraft at the departure runway queues and **_***minimize the amount of time an aircraft spends on the ground after being deiced/anti-iced. ***_

**3. Gate hold procedures, when used as part of an LADP, should be initiated at the time the plan is implemented. **_***The application of gate hold procedures during deicing/anti-icing operations are not predicated on other requirements of FAAO 7210.3. ***_

***NOTE-******The pilot-in-command remains the final authority as to aircraft operation. Air traffic is not responsible for tracking or adherence to aircraft holdover times. ***

**4. **_***Coordinate the expected start time, actual start time and stop time of the LADP with the appropriate ARTCC TMU***_**. The ARTCC TMU will forward these times to the ATCSCC. **

**5. **_***Balance the airport flow to accommodate demand***_**. Adjust the arrival rate with the departure rate. These rates should reflect the number of operations expected to occur during deicing/anti-icing conditions and facilitate minimizing the amount of time an ****aircraft spends on the ground after being deiced/anti-iced. **

## 6. Aircraft operators at LADP airports are responsible to comply with issued EDCT times and will not be exempted from compliance with those times.  However, once an aircraft has been deiced/anti-iced, it shall be released unless a Ground Stop applicable to that aircraft is in effect.

## QUESTION #3

**RDU is currently conducting their LADP.**

**There is a Ground Delay Program in effect for Newark (EWR).**

**RDU has a flight deiced and ready to depart for Newark.  EDCT is **_**1735Z**_**.**

**Should this flight have planned to be ready for departure during its assigned EDCT window or was it acceptable to be ready now (1659Z)?**

**What do you think?  **

***QUESTION #3***

## GOOD THINKING!

_***GOOD THINKING!***_

***It certainly ***_***was not acceptable***_*** for this flight to be ready to go so far ahead of the EDCT!  However, since its already been deiced you need to “***_***minimize the amount of time***_*** an aircraft (this aircraft!) spends on the ground after being deiced/anti-iced.”  ***

***Let them go to Newark! ***

## Okay!  Take a flight (on us!) to someplace where ice is just something you find in cold drinks!

***You also remembered that once an aircraft has been deiced/anti-iced, it ***_***shall be***_*** ***_***released ***_***unless a Ground Stop applicable to that aircraft is in effect.  ***

***Also, if you believe aircraft operators are not performing deicing/anti-icing in a manner consistent to meet their EDCT, notify The ATCSCC through the appropriate TMU!  ***

**Okay!  Take a flight (on us!) to someplace where **_**ice**_** is just something you find in cold drinks!**

## Back to reality!  Let’s recap. . . 

_***Back to reality!  Let’s recap. . . ***_

***We’re going to: ***

***Coordinate both the expected start time, actual start time and stop time of the LADP with the ARTCC Traffic Management Unit.  ******The ***_***ARTCC TMU***_*** will forward these times to the ATCSCC.***
*** ***

***Balance the airport flow to accommodate demand. ***

***Adjust the arrival rate with the departure rate. ***

***Minimize the amount of time an aircraft spends on the ground after being deiced/anti-iced! ***

**7. Allocate the available departure slot capacity, when departure rates are reduced because of deicing/anti-icing, consistent with available resources. ****Facilities should consider the following unprioritized list of options when developing departure allocation procedures. ****  **

**(a)  **_**OPTION A**_**: First come, first served. When departure demand exceeds capacity, the AT facility will minimize departure delays at the runway queue by using gatehold or an equivalent procedure. **

**(b)  **_**OPTION B**_**: AT will determine the departure allocation based upon the departure rate and the stated demand, obtained directly from the users, during a specified time period. For example, AT will coordinate with each user and receive their demand for a 15-minute time period. Then based upon the total airport departure demand for the 15-minute time period: determine the number of flights which the user will be allocated, advise each user, and determine which flights they will use to fill their allocation. **

## (c)  OPTION C:  Airport users determine the departure allocation.  AT will notify the users of the departure rate in effect and the users will then advise AT which flights they will use to fill their allocation.  AT will provide input on the coordination process but will not accept an active role in developing the departure allocation. 

**(c)  ****OPTION C:  Airport users determine the departure allocation.  AT will notify the users of the departure rate in effect and the users will then advise AT which flights they will use to fill their allocation.  AT will provide input on the coordination process but will not accept an active role in developing the departure allocation. **

**(d)  ****OPTION D:  AT determines the departure rate and informs the users of the number of operations expected during a specific time period.  AT determines the total percentage of each users' daily operations based upon a "typical busy day" by dividing each of the users total daily operations by the airports total daily operations.  Then, AT determines each users hourly share by multiplying the users daily percentage times the departure rate.  The users will then distribute their hourly share evenly throughout the specific time intervals. **

## NOTE-

***NOTE-***
***1. AT may or may not take an active role in determining the percentage of each users operations on a "typical busy day" and each users hourly share.******2. If a user has only one aircraft scheduled per hour, attempts should be made to accommodate it. ***

## MULTIPLE CHOICE QUESTION #4

***MULTIPLE CHO***_***ICE***_*** ******QUESTION #4***

***An airport has been using their LADP for several hours.  The tower is advised the plan will terminate in five minutes.  The tower should (pick one):***

***Coordinate the stop time of the LADP with The ATCSCC.***

***Resume compliance with Approval Requests (APREQ) when the LADP ends.  There is no need for further coordination.***

***Resume compliance with APREQs, EDCTs and all other current initiatives when the LADP ends.  There is no need for further coordination.***

***Coordinate the stop time of the LADP with the appropriate ARTCC TMU.***
