See chart on page 3 below for details.

1.1.1 Construction areas:

Parallel TWY SP (A portion from the position which is about 420 m from the CL of TWY S5 to the position which is adjacent to TWY S6).

Construction period: H24
TWY S6 (A portion from the position which is adjacent to parallel TWY SP to the position which is about 49 m from the RCL to the North East).

Construction period: From 1600 to 2200 daily (intermittent time among flights or when there is no flight operation).

1.1.2 Closed areas

TWY S6.

1.1.3 Operational procedures during construction period:

Addition of procedures allowing aircraft code C and equivalent backtrack at RWY 31.

For landing aircraft:
1. RWY 31: After landing, aircraft taxi on RWY 31 → TWY S1/S3 → parallel TWY SP → TWY A1/A2 → apron.
2. RWY 13: After landing, aircraft taxi on RWY 13 → TWY S5 (or backtrack at the beginning of RWY 31 → RWY 13 → TWY S5) → parallel TWY SP → TWY A1/A2 → apron.
For departure aircraft:
1. RWY 31: Apron → TWY A1/A2 → parallel TWY SP → TWY S5 → RWY 31 → backtrack at the beginning of RWY 31 for departure.
2. RWY 13: Apron → TWY A1/A2 → parallel TWY SP → TWY S1 → RWY 13 for departure.

1.2 Completion of phase 1: From 1700 on 14 JAN 2025

See chart on page 4 below for details.

1.2.1 Area put into operation:

Parallel TWY SP: A portion from the position which is about 420 m from the CL of TWY S5 to the North West to the position which is adjacent to TWY S6.

1.3.1 Construction period:

Position: Parallel TWY SP (A portion from the position which is about 80 m from the CL of TWY S3 to the North West to the position which is about 28 m from the CL of TWY S5 to the South East).

Construction period: H24
Position: RWY (The starting position which is 100 m from the CL of TWY S4 to the North West and the ending position which is 110 m from the CL of TWY S4 to the North West).

Construction period: From 1600 to 2200 daily (intermittent time among flights or when there is no flight operation).

1.3.2 Closed areas:

Parallel TWY SP: A portion from the position which is about 80 m from the CL of TWY S3 to the North West to the position which is about 28 m from the CL of TWY S5 to the South East.
TWY S4.

1.3.3 Operational procedures during construction period:

Note: TWY A2: Priority usage when moving aircraft from RWY, TWY into apron in order to protect the construction area from the affects of aircraft exhaust aircraft on phase 2.

For landing aircraft:
1. RWY 31: After landing, aircraft taxi on RWY 31 → TWY S3/S1 → parallel TWY SP → TWY S1/S3 → RWY 31 → TWY S5/S6 → parallel TWY SP → TWY A1/A2 → apron.
2. RWY 13: After landing, aircraft taxi on RWY 13 → TWY S5/S6 → parallel TWY SP → TWY A2/A1 → apron.
For departure aircraft:
1. RWY 31: Apron → TWY A1/A2 → parallel TWY SP → TWY S6 → RWY 31 for departure.
2. RWY 13: Apron → TWY A1/A2 → TWY S5/S6 → RWY 13 → TWY S2/S3 → parallel TWY SP → TWY S1 → RWY 13 for departure.
