Kpt. Ing. Luděk Pilný

Structure:

• Radionavigational systems• Radiolocational systems• Communication systems• Lighting system• Display system• Recording system

Radiolocational systems

• RPL – 5• RPL – 5M

Communication systems

• Telephone switchboard VCS 3020X• Radios LPR-96

Lighting system

• Runway end identifier lights (REIL)• Runway end lights• Runway edge lights• Runway centerline lighting system (RCLS)• Touchdown zone lights (TDZL)• Taxiway centerline lead-off lights• Taxiway centerline lead-on lights• Land and hold short lights• A precision approach path indicator (PAPI)

Lighting system

A precision approach path indicator (PAPI)

Display system

Letvis 99-MRadarcentrum R-950 (DVAZ, PAR)AMS-1

Radionavigational systems

• ILS (LLZ, GP)• DME• NDB (TDV-100) and L (TDV-50) • MKR

ILS components

• Localizer• Glide slope (path)• Marker beacons• Compass locator• Approach light sytem• Runway markings

Localizer

• Provides left/right course guidance• VHF signal

ILS theory of operation

Glide slope (path)

• Provides vertical guidance transmits from separate transmitter

• UHV signal• Paired with the localizer frequency

Marker beacons

• Provide ranging informatin• Outer marker allows for G/S check• Both visual and aural indications• Being phased out

Compass locator

• Substitutes for a marker beacon• NDB station• Can be used to navigate to• Low power station

Approach light system

• IFR to VFR transition• Provides lower visibility approaches• Become part of airport environment

Runway markings

• Clear identification of the touchdown zone• Verification of runway width• Identifies runway used
