1 INTRODUCTION
Special landing and departing procedures are implemented at Hamad International Airport (OTHH) for runways 16L/34R and 16R/34L, subject to the procedures and conditions shown hereunder.
Note 1: Pilots unable to comply with the procedures due to their airline SOPs must inform ATC as soon as possible so that alternative clearances may be issued.
Note 2: It is essential that pilots adhere to the OTHH AIP SUP TITLED “Runway Capacity Enhancement at Hamad International Airport” to ensure the efficiency of operations during RRSM.
Note 3: RRSM procedures shall apply to Category 1 and 2 aircraft types as if they were Category 3 aircraft types.
Subject to the ‘conditions for the application of RRSM’ the following procedure(s) may be applied DURING DAYLIGHT HOURS at OTHH.
- two successive landing aircraft; or
- a departing aircraft and a succeeding landing aircraft; or
- two successive departing aircraft.
provided that;
a) The tail wind component does not exceed 5 KT, measured at the landing threshold, and there are no pilot reports of wind shear.
b) MET visibility shall be equal to or greater than 5 KM and the cloud ceiling shall not be lower than 1000 FT and the Air Traffic Controller is satisfied that the pilot of the following aircraft will be able to observe the relevant traffic clearly and continuously.
c) The pilot of the following aircraft is warned i.e. Traffic information shall be provided to the pilot of the succeeding aircraft concerned.
d) The runway is dry and there is no evidence that the braking action may be adversely affected.
e) The controller is able to assess separation visually.
f) Suitable landmarks and markers on the surface surveillance system shall be available to assist the controller in assessing the distances between aircraft.
g) Wake turbulence separation minima shall be applied.
h) Minimum separation continues to exist between two departing aircraft immediately after take-off of the second aircraft.
i) In order to ensure that the preceding aircraft vacates the runway in a timely manner, the pilot shall be advised of the exit at which to plan to vacate.
1.1 Landing following landing:
When the runway‐in‐use is temporarily occupied by other traffic, landing clearance may be issued to an arriving aircraft, provided that the controller has reasonable assurance that the following separation distances/criteria will be met when the landing aircraft crosses the runway threshold:
- RWY 16L:
The preceding landing aircraft has landed and has vacated the runway; or has passed a point at least 2400 M from the threshold of the runway (abeam TWY A5); and is in motion and will vacate the runway without stopping and/or backtracking. - RWY 34R:
The preceding landing aircraft has landed and has vacated the runway; or has passed a point at least 2400 M from the threshold of the runway (abeam TWY A7); and is in motion and will vacate the runway without stopping and/or backtracking. - RWY 16R:
The preceding landing aircraft has landed and has vacated the runway; or has passed a point at least 2400 M from the threshold of the runway (abeam TWY R); and is in motion and will vacate the runway without stopping and/or backtracking. - RWY 34L:
The preceding landing aircraft has landed and has vacated the runway; or has passed a point at least 2400 M from the threshold of the runway (abeam TWY L8); and is in motion and will vacate the runway without stopping and/or backtracking.
Note: Landing RRSM will only be applied between two successive arrivals provided both aircraft have been instructed to vacate at published Rapid Exit Taxiways (RETs).
1.2 Landing following departure:
When the runway‐in‐use is temporarily occupied by other traffic, landing clearance may be issued to an arriving aircraft, provided that the controller has reasonable assurance that the following separation distances/criteria will be met when the landing aircraft crosses the runway threshold:
- RWY 16L:
The preceding departing aircraft will be airborne and has passed a point at least 2400 M from the threshold of the runway (abeam TWY A5), or if not airborne, will be at least 2400 M from the threshold of the runway. - RWY 34R:
The preceding departing aircraft will be airborne and has passed a point at least 2400 M from the threshold of the runway (abeam TWY A7), or if not airborne, will be at least 2400 M from the threshold of the runway. - RWY 16R:
The preceding departing aircraft will be airborne and has passed a point at least 2400 M from the threshold of the runway (abeam TWY R), or if not airborne, will be at least 2400 M from the threshold of the runway. - RWY 34L:
The preceding departing aircraft will be airborne and has passed a point at least 2400 M from the threshold of the runway (abeam TWY L8), or if not airborne, will be at least 2400 M from the threshold of the runway.
Note: Pilots should be aware of the possibility of a go-around when no landing clearance has been received approaching 2 NM from the threshold, with another aircraft lined up or departing.
1.3 Departure following departure:
Take‐off clearance may be issued to a departing aircraft, commencing its take‐off roll from full length, before the preceding departure has passed the upwind end of the runway; provided:
- RWY 16L:
The preceding aircraft is airborne and has passed a point at least 2400 M from the threshold of the runway (abeam TWY A5) and minimum separation will continue to exist, constant or increasing, between the two departing aircraft immediately after take-off of the second aircraft. - RWY 34R:
The preceding aircraft is airborne and has passed a point at least 2400 M from the threshold of the runway (abeam TWY A7) and minimum separation will continue to exist, constant or increasing, between the two departing aircraft immediately after take‐off of the second aircraft. - RWY 16R:
The preceding aircraft is airborne and has passed a point at least 2400 M from the threshold of the runway (abeam TWY R) and minimum separation will continue to exist, constant or increasing, between the two departing aircraft immediately after take-off of the second aircraft. - RWY 34L:
The preceding aircraft is airborne and has passed a point at least 2400 M from the threshold of the runway (abeam TWY L8) and minimum separation will continue to exist, constant or increasing, between the two departing aircraft immediately after take‐off of the second aircraft.
Note: The succeeding departure may commence its take‐off roll subject to the same provisos above when departing from:
- RWY 16L from A11
- RWY 34R from A1
- RWY 16R from L11
- RWY 34L from L1
1.4 Traffic Information Phraseology for pilot of following aircraft:
When applying RRSM in a scenario where the runway is temporarily occupied by a previously landed or departing aircraft, ATC shall provide a warning (traffic information) to the following aircraft when issuing the landing clearance or departure clearance.
The following examples illustrate ICAO standard phraseology that will be used:
- Landing Clearance Phraseology
1) "(Call sign), (traffic Information) (wind) (runway) cleared to land".
2) "(Call sign), (type) departing ahead (wind) (runway) cleared to land" - Departing Clearance Phraseology
1) "(Call sign), (type) departing ahead (wind) (runway) cleared for take-off"
Note: When necessary or desirable in order to expedite traffic, a landing aircraft may be requested to expedite vacating the runway. When there is a requirement to expedite departing traffic, a clearance for immediate take-off may be issued to an aircraft before it enters the runway.
