COM FAILURE PROCEDURE (IMC) FOR DELHI (INDIRA GANDHI INTL) AIRPORT

Arrival procedures:

A/C not following STARs:

1. Outside Delhi Control Zone - Maintain last assigned level or FL65 whichever is higher.

  • For A/C under own Navigation

On A466: After IGINO proceed direct to VOR ‘SKA’ and then follow procedure mentioned under item 1.) above.

  • For A/C under Radar Vectors
  • ClearanceISSUED for instrument approach:

Continue the procedure and land.

  • ClearanceNOT ISSUED for instrument approach:

Proceed direct to VOR ‘SKA’ maintaining the last assigned level or FL65 whichever is higher. If above FL65 descend in the VOR ‘SKA’ holding and then follow STAR/ Instrument approach procedure for the runway-in-use.

A/C following STARs:

1.Outside Delhicontrol zone maintain last assigned level or FL65 whichever is higher.

  • A/C following STAR under own navigation or under radar vectors:
  • Clearance ISSUED for instrument approach:

Continue via STAR and land.

  • Clearance NOT ISSUED for instrument approach:

- Maintain the last assigned level or FL65, whichever is higher

- (1) Proceed to VOR ‘SKA’ to join holding via shortest route (except for aircraft coming from BASOT).

  • Procedures for following RNAV STARs:
  • Procedures for West Flow (RWY 27, 28, 29):
  • ATS routes A466: Leave VOR 'SAM' on STAR SAM 5A maintaining the last assigned level.
  • Crossing DP104 leave the last assigned level to descend as prescribed in the procedure.
  • Reaching DP106 join the holding at DP106 descending to 2600ft.
  • Reaching 2600ft proceed on heading 360°.
  • Thereafter turn left heading 315°/300° to intercept ILS for the runway-in-use by 10NM from touchdown.
  • Procedures for East Flow (RWY 09, 10, 11):
  • ATS routes A466: After VOR 'SAM' set heading to DP103 via DP109 maintaining the last assigned level.
  • Crossing DP109 descend to FL55.
  • Reaching DP103 join the holding at DP103 descending to 2600ft.
  • Reaching 2600ft proceed on heading 360°.
  • Thereafter turn right heading 075° to intercept ILS for the runway-in-use by 10NM from touchdown.

Departure procedures

Pilot Navigation SIDs:

  • Com Failure within 25 DME of DPN
  • Maintain 5500ft or the last assigned level by ATC, whichever is higher, until 25 DME ’DPN’.
  • Thereafter, climb to flight plan level and continue to the SID until termination point.
  • Com Failure beyond 25 DME of DPN
  • Continue to follow the SID,
  • Maintain the last assigned level by ATC, if any, or FL65 whichever is higher for two minutes and then climb to flight plan level.

When under radar vector:

  • Com Failure within15 DME of DPN
  • Maintain last assigned heading until 20 DME, climb to 5500ft or the level assigned by ATC whichever is higher.
  • After 20 DME climb to FL65 or the last level assigned by ATC whichever is higher and proceed directly to intercept the flight plan route.
  • Com Failure BEYOND15 DME of DPN
  • Maintain last assigned heading for two minutes, climbing to FL65 or the last level assigned by ATC whichever is higher.
  • Then proceed directly to intercept the flight plan route.
  • Five minutes after recognition of failure commence climb to flight plan level.
