How does ATC effect separation of aircraft vertically?
ATC effects separation of aircraft vertically by assigning different altitudes; longitudinally by providing an interval expressed in time or distance between aircraft on the same, converging, or crossing courses, and laterally by assigning different flight paths.
How does air traffic control ( ATC ) work?
If it is “uncontrolled” e.g. some helicopter is to take off from some town not served by an aerodrome after an election rally, then the FPL is filed at the nearest controlled aerodrome. Here “controlled aerodrome” means the aerodrome where Air Traffic Services are provided to aircraft. 2. Addressing of FPL
What do you need to know about an ATC clearance?
The altitude or flight level instructions in an ATC clearance normally require that a pilot “MAINTAIN” the altitude or flight level at which the flight will operate when in controlled airspace. Altitude or flight level changes while en route should be requested prior to the time the change is desired.
When does the ATC controller issue holding instructions?
Whenever an aircraft has been cleared to a fix other than the destination airport and delay is expected, it is the responsibility of the ATC controller to issue complete holding instructions (unless the pattern is charted), an EFC time, and a best estimate of any additional en route/terminal delay.
What do pilots need to know about ATC clearances?
Pilots should report to ATC the time and altitude/flight level at which the aircraft reaches the clearance limit and report leaving the clearance limit. In the event of two-way communications failure, pilots are required to comply with 14 CFR Section 91.185.
When do you need an ATC clearance for VFR flight?
An ATC clearance must be obtained prior to operating within a Class B, Class C, Class D, or Class E surface area when the weather is less than that required for VFR flight.
What are the dangers of flying over mountainous terrain?
Your first experience of flying over mountainous terrain (particularly if most of your flight time has been over the flatlands of the Midwest) could be a never‐to‐be‐forgotten nightmare if proper planning is not done and if you are not aware of the potential hazards awaiting.
