Progress 1 Flashcards
What is the upper and lower limit of Saint Lucia CTR?
Upper: 4,500 feet
Lower: Surface
List the functions of Aerodrome Control Towers.
- Issue information and clearances in order to achieve a safe, orderly and expeditious flow of air traffic on and in the vicinity of the aerodrome.
- Shall maintain a continuous watch on all flight operations on and in the vicinity
- Provide Air traffic control service to prevent collision between:
• Aircraft flying within designated area of TWR including aerodrome traffic circuits.
• Aircraft operating in the maneuvering area.
• Aircraft and vehicles operating in the manoeurving area.
• Aircraft and obstructions on the maneuvering area.
• Aircraft landing and taking off. - Provide Alerting Service.
- Provide Flight Information Service.
- Report failure or irregular operation of any equipment, light or other device provided for air navigation or Air Traffic Control service.
- Select runway in use.
What are the upper and lower limits of TMA 2?
Upper: F105
Lower: 4,500 feet
Which ATC Units are responsible for providing Alerting Service and Flight Information Service?
Flight Information Centres in FIR and all ATC Units within Controlled Airspace.
Instructions to VFR flights in Class D airspace are mandatory. List the three (3) instructions/restrictions.
- Visual holding
- Routing instructions
- Level restrictions
List the objectives of the ATS.
a) Prevent collisions between aircraft;
b) Prevent collisions between aircraft on the manoeuvring area and obstructions on that area.
c) Expedite and maintain an orderly flow of air traffic;
d) Provide advice and information useful for the safe and efficient conduct of flights;
e) Notify appropriate organizations regarding aircraft in need of search and rescue aid, and assist such organizations as required.
What type of airspace extends from the surface to a specified upper limit?
Control Zone
Air Traffic Service is comprised of 3 services. What are they?
- Flight Information Service
- Air Traffic Control Service
- Alerting Service
What is the difference between a METAR a SPECI and TAF?
A METAR is a routine report of meteorological conditions at an aerodrome. (Issued every hour, valid for an hour)
A SPECI is a special report of meteorological conditions, issued when one or more elements meet specified criteria significant to aviation.
A TAF - Terminal Aerodrome Forecast is a message with a defined format with the objective to report a weather forecast for a single airport and its vicinity. (Issued every 6 hours, valid for 24 hours)
What is RVSM?
An airspace that reduces the minimum vertical separation between FL 290 - FL410 from 2,000 ft to 1,000ft
What are the angular differences between the following? Same track, reciprocal tracks and crossing tracks
Same track: less than 45°, more than 315°
Reciprocal: more than 135° less than 225°
Crossing: between 45° and 135° and 225° and 315°
Conditions for approving VMC climb/descent in Saint Lucia:
• One aircraft must maintain the FL.
• It is authorized by the Appropriate ATS Authority in Class D and E airspace.
• When requested by flight crew and with ATC approval.
• With the agreement of the flight crew of the other aircraft concerned.
• During the hours of daylight and in VMC;
• Below 10,000 feet (FL100);
• Between two aircraft only;
• For a specified portion of flight;
• The aircraft climbing/descending aircraft must maintain own separation and remain in VMC;
• Alternative instructions and essential traffic information shall be passed by ATC.
List the reporting points within Saint Lucia Airspace and their routes.
TEDDY: G642
TIBOT: R750
KISES: A324
RIBOR: A324
DAMOV: A312
How is the Transition Level in Saint Lucia’s airspace determined?
• FL100 when QNH 1013 or greater
• FL110 when QNH 1012 or less
What is CAVOK?
CAVOK (cloud and visibility OK) is used when the following conditions exist simultaneously:
- Visibility is 10km or more.
- No CB or TCU and no cloud below 5000 feet or Minimum Sector Altitude (MSA) (whichever is the greater)
What information to be included in HOTO?
A. General information, including any variations from routine operations.
B. Other supplementary information relating to the position.
C. The detailed traffic situation.
D. Full weather briefing and weather tendencies for the period of the watch.
An aircraft may be cleared to level that has been reported vacated by a previous aircraft, except:
• When an aircraft is making a cruise climb.
• When the difference in aircraft performance may result in separation loss.
• When in the same holding pattern.
• Severe turbulence is known to exist
