1.1.4 For RNAV 1 SID/STAR operation, ATS surveillance is mandatory. The transition routes have been establish to connect RNAV 1, RNP 1 SID/STAR with the existing ATS routes.
1.1.5 When air traffic condition permits, ATC shall vector aircraft using the shortest track to approach for landing or to intercept the relating airways.

 

1.2  Operational procedure
1.2.1 Aircraft operators/pilots expecting to use RNAV 1, RNP 1 SID/STAR and RNP APCH procedures at Tho Xuan Aerodrome shall fill appropriate navigation capability indicators in flight plan (FPL), as follows:
  1. Insert R (PBN approved) into Item 10a;

  2. Insert D1 (RNAV 1 all permitted sensors) or D2 (RNAV 1 GNSS), insert O1 (RNP 1 all permitted sensors) or O2 (RNP 1 GNSS), insert S1 (RNP APCH) or S2 (RNP APCH with BARO-VNAV) after PBN/ in Item 18;

  3. Specify equipment to support each type of navigation capability in Item 18 and insert them into Item 10a (G, D, I for D1/O1 or G for D2/O2, S1 and S2)

1.2.2 Before implementation of flights, pilots must verify that the navigation database updated to current time and the aircraft position has been entered correctly. Pilots must confirm the entry and exit points on the ATS route assigned on initial clearance and any subsequent changes of route, ensuring the waypoints sequence depicted by their navigation system matches the route depicted on the appropriate chart(s) and their assigned route.
1.2.3 Pilots must not fly a RNAV 1, RNP 1 SID/STAR and RNP APCH procedures unless it is retrievable by procedure from the on-board navigation database and conforms to the charted procedure (this procedure may subsequently be modified in response to ATC clearances). The manual entry, or creation of new waypoints by inserting latitude/longitude or rho/theta values is not permitted. Additionally, pilots must not change any RNAV 1, RNP 1 SID/STAR and RNP APCH database waypoint type from a fly-by waypoint to a fly-over waypoint or vice versa.
1.2.4 Pilots are expected to maintain route centre lines during the operation process, unless authorized to deviate by ATC or under emergency conditions.
1.2.5 Pilots shall comply with altitude assigned by ATC, as well as adhere to the altitude and speed restrictions depicted on the cleared RNAV 1, RNP 1 SID/STAR and RNP APCH procedures. ATC clearance will take precedence if that clearance does not allow the pilots to adhere to the altitude and speed restrictions depicted on the procedures.
1.2.6 In case ATC assigns the aircraft not to conduct the expected procedure, the pilots should not modify the flight plan in the system until a clearance to rejoin the procedure is received or the ATC confirms a new procedure clearance.
1.2.7 During the operation of the RNAV 1, RNP 1 SID/STAR and RNP APCH procedures, ATC and pilots apply the standard phraseology specified in DOC 4444 - PANS – ATM - ICAO, Procedures For Air Navigation Services – Air Traffic Management.
1.3  For departing aircraft
1.3.1 The procedures for departing aircraft includes 2 main elements:
  1. SID; and

  2. Transition route, if necessary.

1.3.2 A transition route starts at the last point of SID to a position from which the aircraft will intercept the ATS route.

 

1.3.3 Altitude restrictions are designed to establish the separation between departing aircraft and obstacles as well as arriving aircraft.
1.3.4 ATC shall issue a clearance for departing aircraft including the following contents:
  1. Call sign;

  2. Clearance limit, normally destination aerodrome;

  3. SID and transition route, if necessary;

  4. Route;

  5. Assigned flight level/altitude;

  6. SSR code; and

  7. Any other related and necessary instruction or information not contained in the SID description

Note: In case a clearance provided SID is not assigned altitude/flight level, the pilots are not allowed to reach the altitude/flight level itself on the SID vertical profile. Pilots shall re-confirm with ATC to assign a specified altitude/flight level to ensure flight safety.

1.4  For arriving aircraft
1.4.1 The procedures for arriving aircraft include 2 main elements
  1. Transition route, if necessary; and

  2. STAR.

1.4.2 A transition route starts from a point on the ATS route to the position that starts the STAR.
1.4.3 Altitude restrictions are designed to establish the separation between arriving aircraft and obstacles as well as departing aircraft.
1.4.4 Approach clearances shall be issued by ATC in accordance with actual operating conditions.
1.4.5 ATC shall issue clearance for arriving aircraft including the following contents:
  1. Call sign;

  2. STAR and transition route, if necessary;

  3. Runway-in-use;

  4. Cleared flight level/altitude; and

  5. Any other related and necessary instruction or information not contained in the STAR description

Note: In case a clearance provided STAR is not assigned altitude/flight level, the pilots are not allowed to reduce the altitude/flight level itself on the STAR vertical profile. Pilot shall re-confirm with ATC to assign a specified altitude/flight level to ensure flight safety.

1.5  For approaching aircraft
1.5.1 The procedures for approaching aircraft include 2 main elements
  1. IAP; and

  2. Missed approach procedure.

1.5.2 The approach procedure starts from an IAF to the THR or the missed approach holding in case aircraft must conduct the missed approach.
1.5.3 Speed as well as altitude restrictions ensure the separation between approach aircraft and obstacle and ensure in compliance with aircraft performance.

 

1.5.4 Landing clearances shall be issued by ATC appropriate to practical operating conditions.
1.5.5 ATC shall issue clearance for approaching aircraft including the following contents:
