ENR 1.5 HOLDING, APPROACH AND DEPARTURE PROCEDURES

1 General

1.1 The holding, approach and departure procedures in use are based on those contained in the latest edition of ICAO Doc 8168 — Procedures for Air Navigation Services — Aircraft Operations (PANS-OPS).
1.2 The holding and approach procedures in use have been based on the values and factors contained in Part III and IV of Vol. I of PANS-OPS, except for transition layer. The holding patterns shall be entered and flown as indicated below.

2 Arriving flights

2.1 Instructions
2.1.1 IFR flights (inclusive FL 150 and above) landing within Doha TMA, will be cleared to a specific holding fix or as instructed by "DOHA RADAR" and may expect further instructions from "DOHA APPROACH" and/or "DOHA DIRECTOR" subsequently.
2.1.2 IFR flights (below FL 150) landing within Doha TMA, will be cleared to a specific holding fix or to a STAR as instructed by "DOHA APPROACH" and expect further clearance from "DOHA DIRECTOR".
2.1.3 Holding procedure shall be carried out with the authorized level until further instructions given by "DOHA RADAR" or "DOHA APPROACH".
2.1.4 Due to the limited airspace within Doha TMA, it is important that all arrivals to the patterns and for the holding procedures are to be carried out as precisely as possible. Pilots are advised to inform ATC if unable to comply with this requirement.
2.2 Speed requirement
2.2.1 All aircraft entering Doha TMA are required to adjust IAS as per the following speeds unless otherwise instructed by ATC:
  1. 210 - 230 KT during the initial approach phase;
  2. 180 KT on base leg / closed heading to final approach and
  3. 160 KT when established on final approach and thereafter 160 KT to 6 NM final.
2.2.2 These speeds are applied for ATC separation purposes and are recommended.
2.2.3 All speed restrictions are to be flown as accurately as possible. Aircraft unable to conform to these speeds must inform ATC and state what speeds can be used. Pilots should also advise ATC if circumstances necessitate a change of speed for aircraft per reasons.
2.2.4 In the interests of accurate spacing, pilots are requested to comply with speed adjustments as promptly as feasible within their own operational constraints.
2.2.5 In the event when traffic sequencing does not require speed limitation, ATC will advise " NO ATC SPEED RESTRICTION".

3 Departing flights

3.1 IFR flights departing from controlled aerodromes will receive initial ATC clearance from the local Aerodrome Control Tower. The clearance limit will normally be at the aerodrome of destination.
3.2 Detailed instructions with regard to routes, turns etc., will be issued after take-off.
