Flight Procedures in VFR Route and Han-gang Corridor

1. Submit Flight plan for Approval

   1. Helicopter pilots planning flights in VFR route have to submit the flight plan to CDC JAOC 2 hours in advance; in the case of an emergency, it may be submitted through line or wireless.

   2. Some sections in the VFR route(CP-12 ~ CP-17) overlaps with P518 prohibited area but CDC JAOC is responsible for flight plan submission and approval. CDC JAOC in turn must notify MCRC of all approved flight plans.

      Some sections in the VFR route(CP12 - CP17) overlaps with P518 prohibit area but CDC JAOC is responsible for flight plan submission and approval. CDC JAOC in turn must notify MCRC of all approved flight plans.

   3. Flight altitude within VFR route(Southern Corridor) is limited in consideration of safety and noise control. Also, national flights serving public purposes and military helicopters will not be permitted if they are simply passing through, except only when necessary. Detailed flight procedures are provided in g.(1) Southern corridor.

   4. CDC JAOC does not assign any SSR CODE to helicopters flying only in VFR route. JAOC uses its own radars to monitor any aircraft deviation from VFR route or violation into R75 and when needed, issues warning broadcasts using guard frequencies.

         Between CP-4(Quarry) and CP-8(Yeomchang Bridge) : 1 100 ft AMSL or above (climbing beyond these altitudes is permitted if authorized by Gimpo Tower)

   9. Cautions

      1. All flights via CP-2 or CP-23 must fly via the CP-1 for noise control in populated areas.

         All flights via CP-2 or CP-23 must fly via the CP-1 for noise control in populated areas

      2. Routes CP-4 ~ CP-8 is close to the Gimpo Airport final approach course, and flight altitudes that provide sufficient separation from controlling barriers located in these routes are unavailable due to such proximity1). Detailed flight procedures are as follows :

         1) The appropriate flight altitude in CP-4 ~ CP-8considering their controlling barriers(skyscrapers - 594 ft, etc) is 1 600 ft. These routes, however, are close to the Gimpo Airport final approach course(1 500 ft ~ 2 400 ft), and close encounters(TCAS alerts, etc.) with traffic in/outbound Gimpo airport are expected when flying at or above 1 600ft. Therefore, the flight altitude has been set at or above 1 100 ft(barrier height 594 ft + VFR route seperation minimum 500 ft ≒ 1 100 ft), and Gimpo Tower's approval is required before climbing.

      1. Eastern corridor is close to or overlaps with Seoul AB(K-16) final approach course, so pilots must be careful of the in/out bound traffic from Seoul AB. Also, pilots must communicate with (VHF 126.2 MHz or UHF 236.6 MHz) and observe Seoul Tower regulations.

         Eastern corridor is close to or overlaps with Seoul AB(K-16) final approach course, so pilots must be careful of the in/out bound traffic from Seoul AB. Also, pilots must communicate with (VHF 126.2 MHz or UHF 292.85 MHz) and observe Seoul Tower regulations.

      2. Route CP-19 to CP-1 is close to Seoul AB (K-16) final approach course, so a vertical flight altitude separation from control barriers in the same route is limited.2) Therefore pilots must accurately identify surrounding control barriers and fly with caution. Pilots should also communicate with Seoul Tower and acquire Aviation Traffic Information. With Seoul Tower permit, pilots may fly above 2 000 ft AMSL.

         2) Considering control barriers (skyscrapers - 630 ft etc.) in CP-19 ~ CP-1, the appropriate flight altitude is over 1 600 ft. The same route, however, is close to the Seoul AB (K-16) final approach course (2 900 ft ~ 1 000 ft). Thus when pilots maintain flight altitude at or above 1 600 ft, close encounters with in/out traffic from Seoul AB (K-16) might trigger TCAS alerts. Therefore, the flight altitude is set at 1 500 ft ~ 800 ft and with permit of Seoul Tower, pilots may elevate their flight altitude.

         2) Considering control barriers (skyscrapers - 630 ft etc.) in CP-19~1, the appropriate flight altitude is over 1 600 ft. The same route, however, is close to the Seoul AB (K-16) final approach course (2 900 ft ~ 1 000 ft). Thus when pilots maintain flight altitude at or above 1 600 ft, close encounters with in/out traffic from Seoul AB (K-16) might trigger TCAS alerts. Therefore, the flight altitude is set at 1 500 ft ~ 800 ft and with permit of Gimpo Tower, pilots may elevate their flight altitude.

      3. CDC JAOC will cooperate with Seoul Tower and restrain issuing warning broadcasts to helicopters flying through CP-20 and CP-21. (There were numerous cases in which Seoul Tower mistook helicopter to be flying in R75 and sent out warning broadcasts.)

         CDC JAOC will cooperate with Seoul tower and restrain issuing warning broadcasts to helicopters flying through CP-20 and CP-21. (There were numerous cases in which Seoul Tower mistook helicopter to be flying in R75 and sent out warning broadcasts)

      4. Arrival and departure from corridor is only allowed via CP-21 and CP-1, and in case of departure via CP-21, Misari HALO zone must be avoided.

      5. In case of flight from CP-23 to CP-2, pilots must pass CP-1 to control noise and avoid densely populated areas (schools, apartment complexes, Lotte Tower). Direct flight is prohibited.

      6. For safety reasons, helicopters passing through routes controlled by Seoul Tower wishing to fly besides the pre-determined VFR route must acquire permission from Seoul AB (K-16) JAOC and control tower 2 hours in advance.

         For safety reasons, helicopters passing through routes controlled by Seoul Towerwishing to fly besides the pre-determined VFR route must acquire permission from Seoul AB (K-16) JAOC and control tower 2 hours in advance.

Warning Fire etc.

1. Despite repelling actions such as warning broadcasting according to the b. Warning Broadcasting (1), if the aircraft and such continues to demonstrate aggressive maneuvers (noncompliance with controlled speed, dive, deviation from planned altitude or route) and flies towards P73 NFZ, the CDC commander can take necessary tactical actions such as firing warning shots.

2. If the aircraft and such continues to demonstrate aggressive maneuvers (noncompliance with controlled speed, dive, deviation from planned altitude or route) and intrudes into P73 NFZ despite the warning shots, it will be considered a hostile act, and the CDC commander may shoot it down in accordance with the rules of engagement(ROE).

3. If a civil aircraft without approval is identified to have entered R75 Restricted Area due to an unavoidable reason (weather, communications failure, mistake in navigation, malfunction of flight control equipment, etc.), warning shots will not be conducted, but the situation of such aircraft must be tracked by communication with air traffic control center or aircraft, and take repelling actions if necessary. However, if the aircraft does not follow the repelling action and continues to demonstrate aggressive maneuvers (noncompliance with controlled speed, dive, deviation from planned altitude or route), the CDC commander may use armament in self-defense.

4. If a civil IFR aircraft is considered to fly into the P73 or inside of the R75 Restricted Area with an unavoidable reason(bad weather, communications failure, malfunctioning of flight control equipment or HI-JACKED or etc.), the ATC facilities must provide necessary information such as violation reason and information of the aircraft (call sign, nationality, type of aircraft, current position, final departing point, destination, operating GAG frequency, known VIPs, POB, fuel on board and other information as required) to the MCRC and AOC immediately.

5. If the civil aircraft which is committing flight violation was notified by the ATC facilities with the above information, the aircraft will be considered as [unavoidable P73 flight positively identified as civil aircraft]and will not be shot-down.

   If the civil aircraft which is committing flight violation was notified by the ATC facilities with the above information, the aircraft will be considered as 『unavoidable P73 flight positively identified as civil aircraft』and will not be shot-down.

6. If CDC commander receives a report regarding a violation flight by a civil aircraft, or CDC has acknowledged such flight, CDC JAOC must verify whether the flight was unavoidable with the air traffic control center via direct phone call before conducting warning shots.

If CDC commander receives a report regarding a violation flight by a civil aircraft, or CDC has acknowledged such flight, CDC JAOC must verify whether the flight was unavoidable with the air traffic control center via direct phone call before conducting warning shots.

1. If and when an aircraft or another entity intrudes into P73B without prior authorization despite issuing warning announcements according to the b. Warning Broadcasting (1), CDC commander can fire warning shots against such penetrator.

2. In case the aircraft or entity continues to intrude into P73A despite having fired the warning shots, it will be considered as a hostile act and can therefore be shot down. This does not apply to identified civil aircraft. This does not mean, however, that civil aircraft without prior authorization can fly the Flight Prohibited Area without any inevitable reason, and if the civil aircraft is deemed (based on its airspeed, altitude, heading) to attempting to harm intentionally such facilities as critical national infrastructures, it can be shot down.

3. If a civil IFR aircraft is considered to fly into the P73 or inside of the R75 Restricted Area with an unavoidable reason(communications failure, malfunctioning of flight control equipment or HI-JACKED or etc.), the ATC facilities must provide necessary information such as violation reason and information of the aircraft (call sign, nationality, type of aircraft, current position, final departing point, destination, operating GAG frequency, known VIPs, POB, fuel on board and other information as required) to the MCRC and AOC immediately.

4. If the civil aircraft which is committing flight violation was notified by the ATC facilities with the above information, the aircraft will be considered as 『unavoidable P73 flight positively identified as civil aircraft』and will not be shot-down.

5. If CDC receives a report regarding as violation aircraft which may be civilian aircraft, then it must verify whether or not it is a unavoidable flight.

Not identified aircraft Intercept procedures

1. If and when unidentified targets penetrate into the the R75 Flight Restricted Area, CDC commander and MCRC shall firstly order its evacuation by issuing warning announcements.

2. If the unidentified target does not respond to the warning broadcasts and continues to fly within the R75 Flight Restricted Area, and if an hostile activity can be clearly anticipated based on its position, flight heading, and/or airspeed (descending towards P73 without changes to route and speed), or if such an activity has already taken place, CDC commander shall take appropriate actions in accordance with rules of engagement and related laws.

   If the unidentified target does not respond to the warning announcements and continues to fly within the R75 Flight Restricted Area, if an hostile activity can be clearly anticipated based on its position, flight heading, and/or airspeed, or if such an activity has already taken place, CDC commander shall takeappropriate actions in accordance with rules of engagement and related laws.

3. Identification and Intercept by tactical aircraft should be conducted outside the P73 in principle. However, if intercept within the P73 is required, coordination with the MCRC should be made.

Strobe Light Operations

1. Visual Warning lights (strobe lights) are installed by the CDC around P73 boundary and operating for ease identifying P73 area boundary during night, operating strobe lights are located as to [Table 5]. If required additional strobe lights can be established.
