1. Euromed GNSS II / MEDUSA project Egypt national workshop, CAIRO - 12 March 2014 - NANSC Civil Aviation EGNOS/GNSS service usage, strategies and recommendations Airliner : Egypt Air Egypt Air Airlines

2. EGNOS Benefits - General EGNOS Benefits - approach (LPV) in comparison with NPA Example : Lower DH and lower minima EGNOS Benefits - approach (LPV) in comparison with Baro-VNAV Example : Human error and many corrections EGNOS Benefits - approach (LPV) in comparison with ILS Example : Doubtful trust in ILS serviceability GALILEO Benefits Airline fleet ; related capabilities Expectations

3. EGNOS Benefits General More accurate navigation More reliable navigation ( use / dont use, estimated residual positioning error : Integrity ) ( horizontal Alert Limit from 0.3 NM (556m) to 40 m ) ( Vertical Alert Limit 50 m ) Africa has an appropriate location (EGNOS foot print/EGNOS extension to cover North-Africa ) and is in need Over half of all accidents occur during the final approach and landing stages

4. LPV benefits # NPA Lower decision height, lower minima Stable Airspeed, ROD* and FPA* (No intermediate step down ) Flight Director is a command instrument CFIT decreases Minimize arrival flight time and hence fuel Reduce noise levels # NPA has a low safety record (most common accident/incident cause is descent below MDA(H) EGNOS Benefits Approach * ROD : Rate of Descent (ft/min), FPA : Flight path angle Safety increases Delay and Cancellation of flights decreases (i.e. Aerodrome capacity gain in low visibility) Diversion decreases

5. LPV #NPA Lower DH and lower minima LFBD Bordeaux Merignac RNAV (GNSS) Rwy 05

6. LPV benefits # Baro VNAV Baro VNAV is restricted to a minimum temperature Altimetry is based on ISA density variation Cold temperature correction Low pressure correction Hot temperature neglected although affecting Destination altimeter subscale setting and human error Check by RA and EGPWS (2500 AGL) (workload)

7. LPV #VNAV Human Error / Many Corrections Effect of one inch high altimeter setting Unusual barometric pressure, such as 28.29 in Hg (low pressure), when in Hg unit is used, may be set, by mistake, to a more usual 29.29 in Hg, resulting-in the true altitude (i.e. the aircrafts actual height above MSL, being 1000 ft lower than indicated. In most of baro-VNAV approach

8. LPV benefits # ILS Dependant on an international source Depends on national management / local navaid A/C Flight path is loaded in the A/C Nav. Data Base Broadcasted Extends its service to all runways Each runway is funded individually

9. A0999/14 NOTAMR A0998/14 Q) XXXX/QNAAO/IV/B/AE/000/999/….N…..E… A) XXXX B) 1401160733 C) PERM E) TRUST US AND DO NOT BELIEVE WHAT THE PILOTS SAY. THE ILS IS OKAY AND OPERATIONAL 100%. CREATED: 16 Jan 2014 07:41:00 SOURCE: XXXXYNYX LPV #ILS TRUST It happened : (a) flight(s) was(were) dispatched, with marginal weather conditions, according to the ILS minima, and after their return, the crew reported that the ILS was U/S. ( FICTIONAL NOTAM )

10. GALILEO Benefits EGNOS is paving the path for GALILEO Under civilian control Interoperable with GPS and GLONASS More increase in navigation positioning accuracy Is vital where there is a lack of ground based navigation solution

11. Airline Fleet Related Capabilities GPS receivers, autopilot and navigation system will need updating to be EGNOS capable RNP 4 is in progress ( for RNP 10 A/Cs )

12. EGNOS/GALILEO Expectations More extension/coverage over Africa More routes/airspaces based on GNSS and PBN capabilities Technical assistance, training and cost-benefit analyses are expected
