Air Traffic Control And IFR Flashcards
When did the federal regulation of air traffic begin
1926
What are the two air traffic services of most interested to pilots
Flight Service Stations preflight and in flight services
Tower, Approach and Departure Services responsible for separation
What is a Tracon?
A Tracon is a terminal radar approach control
When is the pilot responsibility to avoid traffic and obstructions
When in VFR conditions
What three dimensions do ATC refer to in terms of traffic?
Longitudinal, Lateral and Vertical
Which two systems does ATC rely on to control air traffic?
Radar primary
ADS-S automatic depended surveillance broadcast
How much separation is given to aircraft by ATC?
Within 40 NM of the antenna sight from other aircraft or obstructions
Vertical Separation up to FL410 between aircraft and above FL410
Horizontal separation between aircraft
Within 40 NM of the radar antenna 3NM of separation
Vertical separation in 1000 ft
From Fl290 to FL410 - reduces vertical separation RVSM aircraft and crew authorization required
Above FL410 2000 ft separation
Horizontal non-radar separation 10minutes
What is a large verses heavy aircraft?
Larger 41,000 pounds
Heavy 300,000 pounds
When are pilot of IFR flights required to make position reports ?
What is a position report?
In non radar environments or radar outage or when ATC tells you radar contact is lost
- Identification
- Position
- Time over reporting point
- Altitude or flight level
- Type of Flight Plan: IFR
- ETA and name of next reporting point
- Name of Reporting Point after next
What must you do if conditions are less than vfr
File and IFR flight and receive ATC clearance when the weather is less than VFR.
Note Class G airspace is not controlled by ATC
If there is no tower the you must call in to close your VFR flight plan
Who controls area around a terminal and to what altitude die does the approach airspace extend to ?
If there is no tower who controls the IFR and VFR departures and Arrival?
TRACON terminal radar approach
Approach Air Space Extended to 10,000 to 12,000 ft
ARTCC air Route Traffic Control Center controls arrivals and departures outside of approach airspace. Pilot must close flight plan either after landing or before landing if in VFR conditions
How many ARTCC control the airspace in the lower 48 states ?
What do the ARTCC boundary’s look like a chart?
20 center in the lower 48 states
Minnesota is controlled by ZMP.
The boundary’s are blue square zig zag with a line running though the center
What do remote ARTCC centers look like on a chart and what do the frequencies mean
The centers are surrounded by a square shape formed by a square shaped zig zag line
ARTCC discrete Sector Frequencies
Left civilian frequency
Right UHF military frequency
Boundaries are not charted and you will only know that a boundary is being crossed by a frequency change
What are the 4 different types of Airways in the United States?
A / D extra
Victor (VOR) airway
Jet (VOR) route
Q/T (RNAV) Route
Colored (NDB) Route
Arrival and Departure Routes
What are Victor Airways
Victor airways (V100) VOR federal airways
Range from 1200AGL to 17999MSL
4NM on either side of the airway line on a chart
Highest Assigned altitude is 17000 ft
What are high altitude Jet Routes?
Show on a chart as Jxx (J24)
Extend from 18,000 MSL to FL 450
Air Craft about FL 450 navigate by point to point navigation
What are Q-routes (RNAV)
High Altitude RNAV routes
Shown on Chart as Blue lines with a Q45 identification
What are T-Routes(RNAV) ?
T-routes are low altitude RNAV routes used for transition around busy airspace
What are Colored routes and where are they found
Based on Low medium frequency NAV aids
Based on 4 colors Red R10 Green G11 Amber A12 Blue B13
Colored Air Routes are found in North Carolina and Alaska
What are the different classes of VORs used for airways ? Why are their standard service volume
High Altitude Service Volume 1000-14,500 40NM range 14,500-17999 100 NM range 18000-FL450 130NM Range FL450-FL600 100NM range
Low Altitude Service Volume
1000-18000 40 NM range
Terminal Service Volume
1000-12000 25 NM range
What altitude should you be flying east and west
From 0 to 179 odd altitude thousands
From 180 to 359 even altitude thousands of feet
What does the MEA on a Victor Airway mean
Minimum en Route Altitude to guarantee VOR navigation coverage but not communications or radar coverage
Seen as the first number above the Victor Route identifier example V212
What is MOCA for a Victor Route and how is it identified on a chart ?
MOCA minimum obstruction clearance altitude guarantees navigation coverage within 22 NM of the station
List on a chart as the second number with a *2000
About the Victor Route identifier
If you can’t maintain_________descent or climb rate you must notify ATC.
500 fpm
If you your airspeed varies from the field TAS you must notify ATC
+- 5% or 10 knots
What is a SID?
A standard instrument departure common for airports in busy terminal air space.
Graphic departure procedure designed by ATC Used to Standardize traffic flow, ensure air craft separation and provide obstacle clearance
SID require ATC approval to fly see the chart for the top altitude and departure control frequency
What is the ODP?
Instrument Obstacle Departure Procedure may be text or graphical
Textual is located in the take off minimums section
Graphical is grouped in with the SIDs
Pilots responsibility to follow guidance - ATC will not issue a clearance for ODPs
Should be flown when the weather is less than VFR unless ATC issues a SID or radar vector. If ATC clearance conflicts with a ODP clarify with ATC.
A controller can’t cancel or lower an altitude published on a SID or ODP
What is the standard IFR climb procedure for ft per NM and altitude before turning
- Climb at least 200ft per NM
2. 400 ft AGL before turning
What slope does the FAA use in evaluating obstacles ?
152 ft AGL and 1NM from the departure end of the runway
If no obstacle penetrate the slope obstacle procedures are not published
200 ft per 1 NM required rates of Climb
90knots = 300 fpm
120knots = 425 fpm
