S-mode på sbs

[Boeing]

Det har tidligere vært nevnt her inne at fra mars av skal alle større fly ha såkalt s-mode på sin transponder. Hva er status her? Var det bare tull eller?

[ATC-flyradar]

Iflg loggen så er fremdeles fly som kommer bare som * og ikke viser seg på kartet, så hva status er nå vites ikke.

Kanskje noen i "flytårnet" kunne svare på dette! - Ballen går videre.

Inen 31. mars 2007 skal alle fly med MTOW over 5.700 kg eller har en marsjfart på over 250kt TAS være utstyrt med transponder MODE S (eller det som heter "Mode-S Enhanced Surveillance").

Hmmm, ser ikke slik ut.

[ATC-flyradar]

Jeg vet ikke om gutta på ATCC og/eller gutta på tårnet vet noe om dette. Antar de ikke ser forskjell på de ulike mode som finnes til ulik bruk.

Noen her som har en forklaring til oss.

Mode S and ACAS Programme

Introduction

Secondary Surveillance Radar Mode Select (SSR Mode S) is a development and enhancement of 'classic SSR'.

Aircraft Collision Avoidance System (ACAS) improves air safety by acting as a "last resort" method for preventing mid-air or near collisions between aircraft.
ACAS II is the latest operational development of this technology.

Mode S


There are 2 levels of Mode S functionality:

- Elementary Surveillance (ELS), initially being implemented by Belgium, France, Germany, Luxembourg, the Netherlands, Switzerland and the United Kingdom.

- Enhanced Surveillance (EHS), initially being implemented by France, Germany and the United Kingdom.

In brief, the latest date for aircraft compliance with Mode S ELS/EHS is 31 March 2007. In the case of EHS this is subject to operators applying for an exemption from the Mode S Exemption Coordination Cell (ECC). Exceptionally, an exemption may be granted for a small proportion of an operators’ EHS applicable fleet until 31 March 2009. Separate comparable exemption arrangements apply for State aircraft.

ACAS

ACAS-II implementation has been organised in 2 phases:

- Phase 1, with effect from 1 January 2000 for all civil fixed-wing turbine-engine aircraft having a maximum take-off mass exceeding 15 000 kg, or a maximum approved passenger configuration of more than 30.

- Phase 2, with effect from 1 January 2005, but with a transition phase until 31 March 2006, for all civil fixed-wing turbine-engine aircraft having a maximum take-off mass exceeding 5 700 kg, or a maximum approved passenger configuration of more than 19.
