StORM48: To je Class A airspace (18000+ ft), a postoji ih još 5 (B-G). Podela na low i high je nešto sasvim drugo. Kad kažem "nekontrolisan vazdušni prostor", mislim na prostor gde civilni saobraćaj NE POSTOJI, pa se gotovo smatra "rezervisanim" za male biznis džetove.
Ode ti u USA. U Evropi i ostatku sveta je malo drugacije. USA koristi modifikovanu ICAO klasifikaciju vazdusnog prostora u odnosu na ICAO standard (a koji se primenjuje u Evropi). Osim toga i u Evropi postoje neke razlike u podeli klasa vazdusnog prostora (u Nemackoj ili V. Britaniji, drugacija je podela upper i lower sektora). Trebalo bi da se u narednih par godina usvoji jedinstveni vazdusni prostor u Eurocontrolu, sto ce olaksati stvari u vazdusnom saobracaju.
Class G airspace u USA jeste nekontrolisan do 1500 ft AGL, ali nije rezervisan samo za male biz dzetove, vec za sve koji se nadju tu.
ICAO podela glasi:
* Class A: All operations must be conducted under Instrument Flight Rules (IFR) or Special visual flight rules (SVFR) and are subject to ATC clearance. All flights are separated from each other by ATC.
* Class B: Operations may be conducted under IFR, SVFR, or Visual flight rules (VFR). All aircraft are subject to ATC clearance. All flights are separated from each other by ATC.
* Class C: Operations may be conducted under IFR, SVFR, or VFR. IFR aircraft are subject to ATC clearance. VFR aircraft require radio contact prior to entering airspace (Not to be confused with ATC clearance). Aircraft operating under IFR and SVFR are separated from each other and from flights operating under VFR. Flights operating under VFR are given traffic information in respect of other VFR flights.
* Class D: Operations may be conducted under IFR, SVFR, or VFR. IFR aircraft are subject to ATC clearance. VFR aircraft require radio contact prior to entering airspace (Not to be confused with ATC clearance). Aircraft operating under IFR and SVFR are separated from each other, and are given traffic information in respect of VFR flights. Flights operating under VFR are given traffic information in respect of other VFR flights.
* Class E: Operations may be conducted under IFR, SVFR, or VFR. Aircraft operating under IFR and SVFR are separated from each other, and are subject to ATC clearance. Flights under VFR are not subject to ATC clearance. As far as is practical, traffic information is given to all flights in respect of VFR flights.
* Class F: Operations may be conducted under IFR or VFR. ATC separation will be provided, so far as practical, to aircraft operating under IFR. Traffic Information may be given as far as is practical in respect of other flights.
* Class G: Operations may be conducted under IFR or VFR. ATC separation is not provided. Traffic Information may be given as far as is practical in respect of other flights.
U sustini, u kontroli leta postoje upper i lower sektori koji su kontrolisani (do i od odredjenog nivoa leta), bez obzira na klasifikaciju. Upper sector je od odredjenog nivoa leta (preko FL100, u USA preko FL180, u Britaniji preko FL195 u Nemackoj preko FL285 recimo) i lower sector ispod tih visina. Oba sektora su itekako kontrolisana. I kontrola leta je tako i organizovna...
