AIP PORTUGAL ENR 1.6-1 ENR 1.6 RADAR SERVICES AND PROCEDURES PROVISION OF RADAR SERVICES WITHIN LISBOA AND SANTA MARIA FIR / UIR Introduction Air Traffic Control Services within Lisboa and Santa Maria FIR / UIR radar coverage areas, with the exception of Aerodrome Control Service provided by TWRs, will normally be carried out with the use of radar. Many factors, such as radar coverage, controller workload, equipment capabilities, traffic density and the atmospheric / meteorological conditions, may affect the performance of the Radar Services. Radar services are provided within Lisboa and Santa Maria FIR / UIR in accordance with procedures specified in ICAO Doc 4444 - Chapter 8, supplemented by ICAO regional procedures contained in DOC 7030/4. 1.6.1 Supplementary Services 1.6.1.1 The application of Radar Control Services Radar control services provided by Air Traffic Control units are as follows: a. Radar separation of departing, arriving and en-route traffic; b. radar monitoring of air traffic to provide information on any significant deviation from normal flight path; c. radar vectoring when required; (see ENR 1.5-1) d. assistance to aircraft in emergency; e. assistance to aircraft crossing controlled airspace; f. warnings and position information on other aircraft considered to constitute a hazard; g. assistance to aircraft experiencing difficulties in navigation or a failure of two-way communication; h. information on weather within Lisboa primary radar not available (see 1.6-7) 1.6.2 Minimum Levels Levels assigned by radar controller to pilots will provide a minimum terrain clearance according to the phase of flight. 1.6.3 Secondary Surveillance Radar (SSR) capabilities The SSR equipment is: a. Capable of interrogating on Modes A and C; b. capable of decoding up to 4096 codes; c. not associated with primary radar except at Lisboa Airport Radar Station. 1.6.4 Position Reports Air Traffic Control units may instruct pilots to omit position-reports at compulsory reporting points or to report at specially designated reporting points, provided that the following conditions are fulfilled: a. The flight must have been identified and the Mode C read-out must have been checked; b. the flight must have received and acknowledge an ATC clearance;
ENR 1.6-2 AIP PORTUGAL c. when it can be assumed that radar contact can be maintained; d. aircraft without Mode C automatic pressure altitude reporting capability must be in level flight. 1.6.5 SSR Code Assignment 1.6.5.1 Aircraft about to enter Lisboa and Santa Maria FIR/UIR and having received code setting instructions from ATC, shall maintain that setting until otherwise instructed. 1.6.5.2 Aircraft shall acknowledge code setting instructions by readback. 1.6.5.3 Aircraft about to enter Lisboa and Santa Maria FIR/UIR and having not received code setting instructions shall: a. Maintain the code assigned to him when proceeding from an area of SSR coverage; b. setting the transponder on Mode A, Code 2000 if proceeding from an area without SSR coverage. 1.6.5.4 Aircraft immediately prior to the take-off run shall switch the transponder from "standby" to "on". 1.6.5.5 Aircraft immediately after landing shall switch-off the transponder. 1.6.5.6 Aircraft flying VFR outside controlled airspace and equipped with transponder, within SSR coverage, shall set the transponder on code 7000. 1.6.6 Radar and Radio Failure Procedures 1.6.6.1 Radar Failure In the event of radar failure or loss of radar identification, instructions will be issued to restore non-radar standard operation. Reduced vertical separations of 500 FT or 1000 FT when below or above FL410, respectively, VMC clearances, and / or holding patterns may be prescribed as emergency measures. 1.6.6.2 Radio Communication Failure SSR equipped aircraft experiencing radio communication failures will operate the transponder on Mode A, Code 7600. SSR may be used for acknowledging receipt of any instructions, to verify the aircraft receiver. If the aircraft radio is completely unserviceable, the pilot should carry out the procedures of radio failure in accordance with ICAO provisions. The radar controller will provide separation to identified or non-identified aircraft experiencing complete communications failure, as far as possible, from other airspace users that constitute a hazard, until they have left the airspace concerned or have landed. 1.6.7 Emergency Procedures 1.6.7.1 SSR transponder failure and unlawful interference procedures. 1.6.7.1.1 SSR transponder failure 1.6.7.1.1.1 Failure before intended departure In case of a transponder which has failed and cannot be restored before departure, pilots shall: a. Inform ATS as soon as possible and preferably before submission of a Flight Plan; b. plan to proceed, as directly as possible, to the nearest suitable aerodrome where repair can be effected; c. insert in item 10 of the ICAO Flight Plan form under SSR the letter N of complete unserviceability of the transponder or in case of partial transponder failure, the character corresponding to the remaining transponder capability. 1.6.7.1.1.2 Failure during flight
AIRAC 010-08 25-SEP-2008 AIP PORTUGAL ENR 1.6-3 25-SEP-2008 In case of a transponder failure during flight within or bound to enter Lisboa and Santa Maria controlled airspace, pilots may expect that ATC units will endeavour to provide for continuation of flight to destination in accordance with the Flight Plan. After landing, pilots shall make every effort to have the transponder restored to normal operation. If repair cannot be achieved, pilots shall comply with the above provisions for failure before intended departure. The exemption from the requirement for transponder equipment mentioned in 1.6.7.1.1.1 and 1.6.7.1.1.2 may be granted by the supervisor on duty in Lisboa and Santa Maria ACCs whenever conditions permit. Change of ETD, cruising level and / or route of flight may become necessary. 1.6.7.1.2 Unlawful interference procedures Aircraft without prior instruction may set the transponder on Mode A, Code: 7500 in case of unlawful interference; 7600 in case of radio communications failure; 7700 in case of emergencies. 1.6.8 Radar Separation 1.6.8.1 Lisboa FIR / UIR The minimum horizontal radar separation applied within LISBOA FIR/UIR is 8NM, except in areas hereunder mentioned where the following minimum is applied: a. 5NM within the Lisboa Airport Radar Vectoring Area as shown in paragraph 1.6.10; b. 7NM within Porto Radar Vectoring Area as shown in paragraph 1.6.12; c. 10NM within FARO TMA and MADEIRA TMA as described in ENR 2.1; d. 20NM within MADEIRA SECTOR as described in ENR 2.1. No radar vectoring will be provided below 3000FT within Faro TMA. Service is restricted to radar monitoring of air traffic. 1.6.8.2 Santa Maria FIR / UIR The following minimum horizontal radar separation will be applied: a. 10NM within a volume up to 100NM from Santa Maria Radar Antenna and below FL245; b. 20NM elsewhere within a volume of 200NM, centred on Santa Maria Radar Antenna. Within Santa Maria Radar Sector, vectoring will be provided above 5500FT, except within the area bounded by VFL, SOLGI, TIMTO, SOMUL, RODIL, VFL where the minimum vectoring flight level will be FL120 1.6.9 Primary Radar (PR) and Secondary Radar (SSR) Stations Lisboa Airport Radar Station: Location: 38 45 50.04N 009 08 20.01W Operational Range: PSR 60NM (15 RPM) - See radar coverage charts on paragraph 1.6.11 Operational Range: MSSR - 240NM (15 RPM) - See radar coverage charts on paragraph 1.6.14 Faro Airport MSSR Station Location: 37 00 37.02N 007 58 26.03W Operational Range: 220NM (15 RPM) - See radar coverage charts on paragraph 1.6.14 AIRAC 010-08
