The snow removal procedure

The LIMA GmbH

25 advantages of the SRP shortly summarized

not any unnecessary purchases, transports or consumptions of fuel as a result of holding patterns due to the fact that a stable approach planning can be guaranteed as it is done during the summer months
no unload of freight and passengers at the port of departure as a result of irregular payload reductions as a consequence of additionally necessary fuel loads
reduction of expensive holding patterns and consequent operating hours
keeping to schedules, approaching sequences, arrival and departure times etc.
maximising the runway availability for the air traffic also in case of heavy snowfall
minimising the risks of accident owing to the optimisation of runway conditions and minimisation of contamination
avoiding diversions due to onset of winter
avoiding unplanned passenger stays on stopover airports at the expense of the airlines or at the expense of the passengers as well as avoiding luggage and freight irregularities
avoiding bottlenecks regarding fuel supply on alternates not equipped for several super jumbo jets
avoiding bottlenecks regarding de-icing on alternates not equipped for super jumbo jets
avoiding bottlenecks regarding landing capacity
avoiding double de-icing of aircrafts due to expired hold-over times caused as a result of bottlenecks regarding taking-off capacities
avoiding exceeding working hours and prolonging working hours of crew
avoiding consequential costs like handling, technique, flight security, flight planning, replacement crews, transfer charges to hotel and accommodation for crew and passengers, replacement flights due to alternative landings
avoiding increase of delays e.g. LVO (low visibly operation) and snow removal
avoiding accumulations of snow masses etc. and consequent decision difficulties when a runway has to be closed for safety reason to clear it
avoiding of partially cleared runways and solving the conflict that in case of slippery runway in winter less runway lengths and cleared runway width is available but runway width and length are needed exactly in this situation in winter
no bigger security discounts by worse grip of the airplane tyres in winter than in summer
no sudden runway closures e. g. as a result of pilot reports as a consequence of contaminated runways and minimisation of workload in these situations for air traffic controllers. The air traffic is the ÒmasterÓ the winter road maintenance is the ÒslaveÓ and not the other way round. The SRP uses the time window the winter road maintenance is assigned to. Owing to the permanently high breaking coefficient and to low accumulations of contamination the time windows can be moved in the defined frame without risk
minimising the runway occupation time of the aircrafts by improving the delay coefficient and shortening long braking distances of the landing aircrafts
no unnecessary go-arounds of subsequent aircrafts
minimising the risk of accident by means of steadily secure grip
avoiding engine damages as a result of overheating caused by unnecessary reversal pushdown to the standstill of the aircraft
maintenance of reliability and security of the air traffic also in case of heavy snow fall
avoiding foreign object damage (FOD) e.g. bird strike, damages by foreign substances to the aircrafts
