3.1.1.1. The description of the airspace designated for air traffic service purposes is found in several tables.
3.1.1.2. RNAV 5 airspace has been established throughout the Jeddah FIR except (RNAV 1) ATS routes Y432, T142 and L564 from FL160 up to and including FL600, except in that area East of 04700E and South of 2150N, where the base of the RNAV 5 airspace is FL255. For full details, please refer to GEN 1.5 and ENR 2.2.1
3.1.1.3. The axis of airways is generally a straight line between radio navigational facilities (except M999 which has no navigation aids south of Jeddah) but certain airway centre lines have been displaced from the straight line track to:
3.1.2.1. In general, the air traffic rules and procedures in force and the organization of air traffic services are in conformity with ICAO Standards, Recommended Practices and Procedures. Differences between the national and international rules and procedures, and specific additional rules and procedures are all given in GEN 1.7; the altimeter setting procedures in ENR 1.7 are reproduced in full with an indication wherein there is a difference.
3.1.2.2. In order to prevent possible interception of civil aircraft by Air Defence aircraft, It is stressed that all civil aircraft operations must be conducted within the lateral limits of the relevant ATS route being flown, unless ATC issues a specific clearance for a flight to deviate from its route of flight and fly a direct route to a point or destination.
3.1.2.3. The issue of such a clearance by an ATC unit for an aircraft to deviate from its previously cleared route of flight will only take place if it does not infringe on active military areas.
3.1.2.4. Special terminal area procedures have been promulgated for the Bahrain/Dammam, Jeddah, Abha, Madinah, Riyadh, Tabuk and Taif terminal control areas, all forming part of ENR 1.5.
3.1.3.1. A designated area is established within which the special requirements of ICAO Annex 2 concerning flight plans, two-way radio communication and position reporting apply to all flights in order to:
3.1.3.2. The area so designated comprises the entire airspace of Saudi Arabian territorial land and water areas inside and outside Jeddah FIR.
3.1.4.1. All ATS routes traversing the territorial airspace of the Saudi Arabia have been listed in addition to those contained within the Jeddah FIR.
3.1.4.2. All routes over Saudi Arabian territorial airspace and within Jeddah FIR are within the designated area specified in paragraph 3 above within which all flights shall fill a flight plan, maintain two-way radio communication and report position in order to reduce the need for interception for the purpose of identification.
3.1.5.2. Inflight Reports:
Inflight pilot reports are required in accordance with ENR 1.14
3.1.5.3. Pilot reports on automatic self-monitoring VORTACs.
VORTACs DFN and QUN are an improved type with automatic facility status announcement capability.
These VORTACs are dual facilities with up to three electrical generation systems, solar power, battery back-up, etc., largely selfregulating and self-compensating, specifically designed for operation in remote locations.
Every eight minutes, following the IDENT, the VORTAC will broadcast a letter and a number (alpha-numeric) which indicates the
current status on the VOR channel.
The alpha-numeric status codes are as follows:
Each enroutes NAV AID is a CRP. Pilots reporting overhead any NAV AID transmitting status reports, may be requested by ATC to repeat the latest voice status alpha-numeric in their position report.
VORTACs DFN and QUN are an improved type with automatic facility status announcement capability.
Every eight minutes, following the IDENT, the VORTAC will broadcast a letter and a number (alpha-numeric) which indicates the
current status on the VOR channel.
The alpha-numeric status codes are as follows:
| ALPHA | 1 through | ALPHA 8 |
| BRAVO | 1 through | BRAVO 10 |
| CHARLIE | 6 omly | |
| DELTA | 1 through | DELTA 5 |
| ECHO | 1 through | ECHO 5 |
| FOXTROT | 1 only |
3.1.5.4. Emergency Reports:
In accordance with ICAO Annex 10 Vol. II.
3.1.6.1.2. The latitude/longitude coordinates published in the route tables are to the nearest Second. However, the actual NAVAID coordinates used in the route structure computations are those published in Table ENR 4-1.
3.1.6.2.1. The magnetic track is tabulated as either:
Tracks or VOR radials to the nearest degree, geodesic distance to the nearest tenth of a nautical mile between each successive designated significant point and, in the case of VOR radials, changeover points.
The values published have been rounded to the nearest tenth of nautical mile after the application of the appropriate variation.
3.1.6.2.2.1. The values published have been rounded to the nearest whole NM.
3.1.6.2.2.2. COP at mid-point between VOR are not listed.
3.1.6.3.2.1. The altitude in effect between radio fixes which assures acceptable navigational signal coverage and meets obstacle clearance requirements between those fixes.
3.1.6.3.2.2. MEA values are determined by flight check or signal coverage simulation and published up to and including FL 240. When on MEA value is shown a VOR signal gap exists at FL 240, as indicated in Column 6 (Remarks), and full signal coverage either occurs at a higher level or ceases to exist; in such cases, and for aircraft operating below the published MEA, an alternative method of navigation may be required.
The MOCA provides the required MOC above obstacles contained inside the obstacle clearance areas for the entire route segment.
3.1.6.4.1. The lateral limits of the control areas which encompass the ATS routes in Saudi Arabian territorial airspace have been determined in accordance with the criteria specified in the ICAO Doc. 9426.
The lateral limits of the protected airspace of an ATS route tracks:
