The table on the right lists the common frequencies used as departure frequency by HPN Clearance Delivery. The first available controller in this list should be handling departures.

Note that this table only serves as a guide. The actual departure frequency has to be determined based on coordination with the other online controllers.

If there is no other controller online that would accept departures from HPN, advise the pilot that Departure is offline.

The initial altitude for IFR departures is 3,000'. None of the SIDs at HPN have published altitude restrictions, so "maintain phraseology" must be used.

PHRASEOLOGY
MAINTAIN (altitude).

The HPN# Departure (pronounced Westchester #, such as Westchester Eight) is the standard departure procedure for HPN departures, and should be assigned to all aircraft.

The PROP# Departure is valid only for runway 16 departures, when requested by NY TRACON. It must not be issued otherwise.

HPN is located inside the Westchester County Class Delta Airspace.

VFR aircraft are NOT required to obtain a clearance before departing, but may request flight following.

Issue the following instructions to aircraft requesting flight following on the ground:

1. Advisory to remain outside New York Class Bravo Airspace.
2. Initial altitude "at or below 2,500".
3. Departure control frequency in use.
4. Squawk code.

PHRASEOLOGY
REMAIN OUTESIDE BRAVO AIRSPACE.

EXAMPLE
"N825BT, remain outside Bravo Airspace. Maintain VFR at or below two thousand five hundred. Departure frequency 120.55, squawk 0205."

Ground Control

Departure Sequencing

Aircraft should be sequenced to depart in the following order:

1. By alternating gate.
2. If not the above, then by alternating exit fix.
3. If not the above, then by aircraft performance, fastest to slowest.

Intersection Departures and Usable Runway Lengths

The location of taxiway "Hotel" at the intersection of runways 11/29 and 16/34 has led to confusion for pilots requesting an intersection departure. As a safety measure, intersection departures on any runway from "Hotel" may not be approved.

Below is a list of usable runway lengths from intersections which may be used for intersection departures. Issue the measured distance from the intersection to the runway end to any pilot who requests and to all military aircraft. Intersection distances need not be issued to non-military pilots who do not request them.

PHRASEOLOGY
RUNWAY (number) AT (taxiway designator) INTERSECTION DEPARTURE (remaining length) FEET AVAILABLE.

FAA Order JO 7110.65 § 3-7-1(d)

11	16	29	34
K (4,450')	A (6,550')	K (4,450')	A (6,550')
C (3,800')	B (5,800')	A (3,450')	K (5,000')
F (3,000')	C (4,550')	34 (2,800')	29 (4,200')
	D (4,500')	L (2,200')	G (3,350')
	E (3,550')		F (3,100')
	F (3,400')		E (2,900')
	G (3,000')

Local Control

Releases

Releases from Westchester are automatic unless N90 requests individual releases.

Separation

The standard departure separation technique to be used is anticipated radar separation.

Radar and Airspace

Westchester ATCT owns below 3,000' within a 4 mile radius of the airport. The tower also owns below 3,000' up to 6 miles from the airport along the runway 16/34 extended centerline, which laterally extends 1.5 miles on each side.

Westchester ATCT is Limited Radar Approach Control certified.

1. This tower shall NOT radar identify departing IFR aircraft and shall instruct departing aircraft to contact Departure Control once they appear to be clear of any traffic. It is imperative that Local Control observe departing traffic turning towards the assigned climb, heading, or visual reporting point before handing off.
2. Tower MAY radar identify VFR aircraft if necessary for identification and separation/sequencing in the Class D.

Aircraft Exiting the Runway

Arriving aircraft shall be issued a turn onto one of the taxiways parallel to the landing runway to ensure the aircraft continues its taxi away from the runway exit. Handoff to Ground Control after the aircraft starts taxiing away from the active runway. Local Control will coordinate with Ground Control as needed to determine the traffic flow on the taxiways.

Intersecting runway operations

Due to the close proximity of the runway 29 displaced threshold and the edge of runway 16/34 it is necessary to increase separation standards for runway 29 arrivals when runway 16/34 is being used simultaneously. Therefore, for the purpose of separation, Local Control shall ensure that an aircraft arriving runway 29 does not cross the “original” threshold of runway 29 until:

1. The aircraft landing runway 16/34 has passed the intersection of runway 29 or has completed landing roll and will hold short of the runway 29 intersection, or
2. The aircraft departing runway 16/34 has passed the intersection of runway 29 or is airborne and turning to avoid conflict.

For all other situations, apply FAA Order 7110.65 standards and use the runway 29 displaced threshold as the separation point.

Land and Hold Short (LAHSO)

LAHSO may only be used with the following runway configurations:

1. Land runway 16 to hold short of runway 11/29. Available Landing Distance (ALD) is 4,000 feet and aircraft groups 1, 2, 3, and 4 are authorized.
2. Land runway 11 to hold short runway 16/34. ALD is 2,500 feet and only group 1 aircraft are authorized.

LAHSO may only be conducted under daylight VFR conditions (ceiling 100' and visibility 3 miles) and the ALD of the LAHSO runway must be dry. Dry is defined as no visible moisture.

VFR Pattern Work

Aircraft conducting pattern work on runway 11/29 shall be instructed to make their downwind over the numbers of runway 16 or 34 as appropriate for the current configuration, to separate pattern work aircraft from IFR arrivals.

PHRASEOLOGY
MAKE YOUR DOWNWIND OVER THE RUNWAY (runway) NUMBERS.

EXAMPLE
"MAKE LEFT CLOSED TRAFFIC, MAKE YOUR DOWNWIND OVER THE RUNWAY 34 NUMBERS, RUNWAY 29, CLEARED FOR TAKEOFF."

The calm wind configuration is landing and departing runways 34 and 29. When the wind is in excess of 4 knots, select the runway configuration most operationally advantageous and aligned with the wind. IFR traffic must use runway 16/34 only.

IFR departures will fly the assigned SID. No additional phraseology is necessary.

PHRASEOLOGY
CLEARED FOR TAKEOFF.

IFR departures not assigned or unable to fly the assigned SID must be released on a heading provided by NY TRACON.

Runway	Heading	Altitude
11	090	2200'
16	090	2200'
29	340	2000'
34	340	2000'

TRACON

TRACON services for Westchester County Airport are provided by New York TRACON (N90).
