Contributing factors
Flight handling (unstabilized
approach,glide slope deviation,
speed…)
Technical failures
(thrust reversers,
brakes, tyres …)
Timely crew decisions
(no go-around, late
rejected take-off …)
Runway
excursion
Meteorological
conditions
Wet/contaminated runway is a predominant factor identified in
studies on runway excursion
Runway conditions

Information on wet/contaminated runway
Main issues identified for information* on runway condition :
relevant and simple information
reliable and objective information
harmonisation
availability and timeliness of information
* Information is also given via NOTAM/SNOWTAM but those issues
are presently analysed within the framework of short notice
information given by ATC,ATIS or future datalink systems

Relevant and simple information
Meaningful data for pilots to assess landing distance accurately :
appropriate data for inflight landing distance assessment or for
system being developped by the industry (computation issues for
landing distance or crosswind limitation on wet/contaminated runway)
simple information being easily handled by airport operators and ATC
and not overloading communications or pilots (for instance balance
between datas on all contaminated parts of runway and the minmum
information required for appropriate braking action)

Reliable and objective information
Data resulting of measures must be reliable
and accurate (like all measurement
processes) :
performance criteria for the approval of
friction measuring devices (accuracy,
repeatability, reproductibility, stability, etc.)
measuring friction with proven methods and
competent personnel
Use of human perception must be controlled :
some airports test braking action with land vehicles
Pilot Reports PIREP (FAA : used only to downgrade runway condition
code)
depth of contaminant : methodology and measuring devices (coin
method, radar, others)

Harmonisation
Various studies or benchmarking have pointed out widely
varying pilot information practises.
It is not possible for all airports to transmit precisely the
same set of datas but pilots need a common and simple
framework of data and communication in order to easily
carry out their in flight landing distance assessment.

Availability and timeliness of information
Conflict between the need to refresh information especially
after meteorological events (showers, rainfall, etc.) and the
occupancy time of the runway :
methods for runway friction assessments according to the
periodicity or triggering event
efficient measuring devices for depth of loose contaminant (coin
method or rapid and accurate equipment ?)
theoretical estimation/prevision of depth based on pavement
structure and meteorogical events characteristics
cartography of runway and critical areas for adapted operating of
measuring devices

Works in progress
Civil aviation community is working continuously on these
issues :
ICAO : FTF circular on runway surface condition
assessment, measurement and reporting; amendment to
SARPS and PANS
FAA : TALPA ARC (runway condition assessment table,
etc.)
EASA : RuFAB and workshop in April 2010 in Paris ;
ECAST
Eurocontrol : EAPPRE
many studies on friction, new measurement devices,
estimation of contamination

Conclusions
Global and simple reporting format (no change when crossing borders)
Reliable process of assessment (proven procedures, competent and trained staff, calibrated equipment, controls)
Better understanding of inter action between aircraft (not only tyres) and contaminated runway (collection of data, modelisation, experiments, etc.)
Coordination between various works carried out by organisations, CAAs and industry (no duplication, cross feeding, etc.)

With this access point to the EUMETCast system, AMD can receive satellite images and products from the EUMETSAT operational geostationary satellite, Meteosat-8, which is located over the Indian Ocean at 41.5 degree East. (...) Extensive hydrometeorological and FFG operational training was provided to AMD meteorologists and hydrologists through on-the-job training at the WMO Regional Training Centre hosted by TSMS.
(...) Based on WMO competency requirements, the training was aimed at developing local capacities for providing timely and accurate hydrometeorological services as well as ensuring their long-term sustainability.

This RFI relates ONLY to seeking information from the market for the first phase, the provision of advisory and consultancy services for assisting the UN in the definition and determination of the solution for its air operations management.
Background
Aviation support plays a critical role in United Nations peacekeeping operations. (...) One of the primary purposes of the new software solution is to have a single database for contract costing information, from which the operational data in terms of aircraft utilization, can accurately determine the precise invoice cost for an invoice period.
(...) The new system shall be the source of record for Contracts, Operations and Invoicing Tracking thus supporting the business process end to end.

The infographics I produce enable the country operations to make informed decisions to facilitate the provision of aid where it is needed. --Oladipo Akinpelumi, UN Volunteer GIS Officer with OCHA, Iraq
Other volunteering activities Oladipo engages in include providing support on security and ensuring that the warden lists of OCHA Iraq staff are accurate and up-to-date.
He also provides technical support for the coordinated assessments conducted in Iraq, such as the Rapid Needs Assessment in areas that have just opened to humanitarian access, or where there is little information available.
(...) This means that Oladipo must ensure that his data is reliable, accurate and up-to-date as possible.
Collecting data is not just a matter of numbers.

This means that the tangible products expected from the IP must be specified as accurately as possible at output / component level to allow for more accurate indicative cost estimates, which can then be developed into detailed activity level cost estimates at a later stage. (...) Physical contingencies are usually applied to works, goods and/or services for which reasonably accurate estimates that might be affected by inflation cannot be made. (...) For recurrent costs one could assign incremental operating as well as staffing costs. Expenditure accounts are organized into investment costs and recurrent costs.
