Routing to certain airports in ZNY, ZDC and ZBW ARTCCs is pre-coordinated through letters of agreement (LOA). These routes have been added to the Preferred Route Database. Therefore, PRD must be referenced for all departures.
Notes
- The initial altitude for PHL jet departures is 5,000’ and for PHL prop/turboprop departures is 3,000'. Some intra-TRACON flights also have initial altitudes that are non-standard.
- Aircraft requesting or assigned a final altitude of 4,000' or less shall be issued 3,000' initially.
- Traffic departing PHL routed OOD V157 and PHL..ENO shall be issued an initial altitude of 3,000' unless otherwise coordinated.
PHL#
The normal DP to be used by aircraft departing Philadelphia is PHL # (pronounced Philadelphia (Version #), such as Philadelphia Two). It should always be assigned, unless the pilot indicates not possessing charts, in which case no departure procedure should be assigned and the pilot should be cleared to their destination via radar vectors to a proper PHL exit.
PHL# is basic and involves very little pilot navigation. In most cases, Local Control will assign specific headings to departing traffic depending on their departure exit. The only exception is from 2200 local to 0600 local, a special climb procedure is used when departing runway 27L/R for noise abatement. Climbs are pilot navigated courses flown from wheels up to 5,000’ or amended altitude.
Cleared to (clearance limit), Philadelphia (version #) departure, radar vectors (exit); then as filed. Maintain (initial altitude), expect (final altitude) one zero minutes after departure. Departure frequency (frequency), squawk (code).
PHL Class Bravo VFR Operations
Operation | Departure Runway | Direction | Departure Instructions | Altitude | Departure Frequency |
---|---|---|---|---|---|
VFR w/ Flight Following (Props) | All | All | Fly runway heading | 3000' | 124.350 (Philadelphia Departure) |
VFR w/ Flight Following (Jets) | All | All | Fly runway heading | 4,500' | 124.350 (Philadelphia Departure) |
VFR w/o Flight Following (Props Only) | All | All | Fly runway heading | 2000' | 118.500 (Philadelphia Tower) |
PHL is located inside Philadelphia Class Bravo Airspace. All VFR traffic must be issued a discrete squawk code, and a clearance into the Class Bravo Airspace.
FLIGHT FOLLOWING PHRASEOLOGY
CLEARED THROUGH (THE PHILADELPHIA) BRAVO AIRSPACE, FLY RUNWAY HEADING, MAINTAIN (altitude), DEPARTURE FREQUENCY (frequency), SQUAWK (code).
NO FLIGHT FOLLOWING PHRASEOLOGY
CLEARED OUT OF (THE PHILADELPHIA) BRAVO AIRSPACE, FLY RUNWAY HEADING, MAINTAIN VFR AT OR BELOW (altitude), DEPARTURE FREQUENCY (frequency), SQUAWK (code).
Ground
- Departure Sequencing
Exit Gate | Exits |
---|---|
North Gates | MXE, STOEN, PTW, FJC, MAZIE, ARD |
South Gates | RUUTH, DITCH, OOD, DQO |
- Aircraft should be sequenced to depart in the following order:
- By alternating gate group.
- If not the above, then by alternating exit.
- If not the above, then by aircraft type largest to smallest.
- Coordinate with Local Control at the beginning of a shift if departures will “monitor” or “contact.” Also ensure to coordinate how Local Control would like departure sequence forwarded.
- Due to the complexity of the intersection at 27L, during departure pushes it is imperative that controllers keep track of the departure sequence and which aircraft are on which taxiways. The departure sequence MUST be properly forwarded to Local Control so that there is no confusion on the sequence.
- Before switching departing aircraft to Local Control frequency, ensure the aircraft is aware of his or her number for takeoff. This is important for engine start and warm up times.
- Prearranged coordination for runway crossing
- Ground Control may taxi aircraft across runway 9L, 27R or 26 without coordinating with Local Control so long as
- That runway is being utilized for landing only (not takeoffs).
- At the time the crossing clearance is issued, the traffic crossing that runway must be either holding short or in a position to cross the runway expeditiously without causing a safety risk to any arriving traffic.
- The crossing traffic must initiate crossing of that runway prior to any arriving traffic reaches a 2 mile final.
- The procedure must be completed no later than when the arriving traffic reaches a 1 mile final.
- Tower has the final authority to suspend or resume the prearranged coordination for runway crossing.
- Obstructions to Arriving and Departing Aircraft
- The areas of consideration at PHL airport where a taxiing aircraft could become a potential obstacle to departing or arriving aircraft are as follows:
- Aircraft utilizing taxiway Yankee:
- Could conflict with aircraft departing runway 27R (Simultaneous Approaches to Parallel Runways #2).
- Could conflict with aircraft arriving and departing runway 9L.
- Some simulators show hold short lines on Yankee. This ensures that when approaches to runway 9L are in use, aircraft will hold short of the approach path.
- PHRASEOLOGY
Hold short of runway niner left approach on taxiway yankee.
- Aircraft utilizing taxiway Yankee:
- Taxiways A, A1, A2, and A3 are limited to Airplane Design Group III (wingspan up to but not including 118 feet) aircraft and smaller (B727/MD80/B737, A319, A320).
- Controllers shall ensure that taxiing aircraft operating on non-intersecting runways do not become potential obstacles to arriving and departing aircraft.
- Aircraft Exiting the Runway
- Arriving aircraft shall be issued a turn onto one of the taxiways adjacent to the landing runway to ensure the aircraft continues its taxi away from the runway exit. Ground Control will receive the handoff after the aircraft starts taxiing away from the active runway. Whenever necessary, adjust the ground traffic flow so as to allow arrival aircraft to exit the runway unimpeded.
- Simultaneous Approaches to Parallel Runways #2
- During a Simultaneous Approaches to Parallel Runways #2 (SAPR2) operation, taxi aircraft to runway 27R or runway 35 at Kilo taxiway for departure. (SAPR2 is explained in the Tower section, under the Runway Selection tab).
- Runways 17/35 and 8/26 Restrictions
- Runway 17/35 is limited to Airplane Design Group III (wingspan up to but not including 118 feet) aircraft and smaller (B727/MD80/B737, A319, A320). Runway 8/26 is available for props only and small regional jets. Runway 8/26 departures must utilize runway 8 and arrivals must utilize runway 26.
- Aircraft Movement
- Almost all taxi routes require a runway crossing. It is required per 7110.65 that taxiing aircraft receive and read back a hold short instruction for each runway crossing whether or not the runway is active.
- PHRASEOLOGY
Runway 35, taxi via alpha, delta, hold short runway 26.
- When reaching 26:
- PHRASEOLOGY
Cross runway 26 at delta, hold short runway 27R at delta.
- When reaching 27R:
- PHRASEOLOGY
Cross runway 27R at delta, continue runway 35 via delta and sierra.
- It is suggested that departing aircraft exit the ramp as follows:
- East Flow: Spots 5, 6, 7, or 9
- West Flow: Spots 5, 8 , or 9
- NOTE: When a large departure push occurs during PHL West Ops, have aircraft taxi via Juliet to spot 2 and then exit the ramp. This procedure will allow a large amount of traffic to be sequenced via Yankee and Sierra to 27L.
- It is suggested that arriving aircraft enter the ramp as follows:
- East Flow: Spots 5, 8, or 9
- West Flow: Spots 5, 6, 7, or 9
- For PHL West Ops, arriving aircraft shall utilize taxiway Kilo as much as practical. For PHL East Ops, arriving aircraft shall utilize taxiway Juliet as much as practical.

- Intersection Departures and Usable Runway Lengths
- The sequencing for intersection departures is a bit more involved as it will require Ground Control to properly push the strip to the tower controller in the correct order.
- For intersection departures, state the usable runway distance if that distance is not broadcast in the ATIS. Below is a list of usable runway lengths from common intersections. If the numbers are not divisible to 50, you must round them down to the nearest 50 feet before providing the information to the pilot.
- PHRASEOLOGY
Runway two seven right at echo, taxi via left on kilo, hold short echo. Runway two seven right at echo intersection departure, seven thousand two hundred and fifty feet available

Ground Metering
- Purpose
- Ground Metering’s primary responsibility is to create a departure sequence before aircraft are taxied out for takeoff. Ground Metering sequences aircraft by alternating gate, exit, or type aircraft and then provides the active Ground controller with flight strips in that order. Philadelphia’s Ground Metering frequency is 121.9 (6C). Ground metering operation must be authorized by the TMU
- Ground Metering Procedures and Phraseology
- Once aircraft are ready to taxi, they will call Ground Metering on the published Ground Control frequency that appears on the airport diagram (121.9).
- Aircraft calling Ground Metering should inform the controller of the following information; however, be aware that many pilots will call and advise “ready for taxi” and Ground Metering will have to find them on the field:
- Call-sign
- Location at the airport
- ATIS code
- The Ground Metering controller shall inform the aircraft to hold short of the main outbound taxiway and monitor the active Ground Control frequency.
- PHRASEOLOGY
JetBlue Four Fifty-Two, Philadelphia Ground, hold short of Echo, monitor ground on one two one point six fife, wait for the controller to call you
- Ground Metering VRC Procedural Settings
- Because the metering operations require effective use of flight strips as control elements, the flight strip bay should be used and set up as follows.
- Ground Control 121.65 (6D) should set the following options under Settings > General > Flight Strips:
- Unchecked:
- Auto-Add Arrival Strips
- Auto-Add Departure Strips
- Ignore Pushed Strips
- Checked:
- Delete Strip When Pushed Manually
- Unchecked:
- Ground Metering 121.9 (6C) should set the following options under Settings > General > Flight Strips:
- Unchecked:
- Auto-Add Arrival Strips
- Auto-Add Departure Strips
- Ignore Pushed Strips
- Checked:
- Delete Strip When Pushed Manually
- Unchecked:
- Both controllers will utilize the two-column flight strip bay (Settings > General > Flight Strips > Two-column Flight Strip Bay). Separators can be used for additional organization at the ATC’s discretion. Separators can be added by typing
.sep NAME1|NAME2|NAME3 <Enter>
(refer to VRC documentation for further details on separators).
- Transfer of Control and Pushing Strips
- After Ground Metering 121.9 (6C) has sequenced aircraft that have called for taxi, he or she shall push the strip in the appropriate sequenced order to the active Ground controller on 121.65 (6D) and advise the pilot to monitor that frequency. Ground Control 121.65 (6D) will receive strips in the left hand column of the strip bay and then will move them to the right hand column, in the appropriate order, once taxi instructions have been given.
- After additional taxi instructions are not required, the active Ground controller 121.65 (6D) shall push the strip in sequenced order to Local Control and instruct the aircraft to monitor Philadelphia Tower on the appropriate frequency.
