302 - ATC Support

What are the four sections of an instrument approach procedure?

initial, intermediate, final, missed

Where is the initial approach segment?

Between thee initial approach fix and the intermediate approach fix

What points mark the intermediate approach segment?

The intermediate approach fix and the final approach fix

What marks the final approach segment?

The final approach fix and the runway, airport, or missed approach point

What is the difference between precision and non-precision approaches?

Precision approach provides both vertical and lateral guidance but non-precision only provides lateral guidance

Which type of approach uses a decision height?

Precision approach

Which type of approach uses a minimum decent altitude?

Non-precision

What is a contact approach?

When an IFR aircraft is cleared to deviate from the IFR approach and continue to the airport by visual reference to the surface of the earth. Minimum of 1SM flight visibility

What is a visual approach?

When an aircraft on an IFR flight plan operating in VMC may proceed to the airport of destination.

What is a simulated approach?

An instrument approach conducted in VMC by an aircraft not on an IFR clearance.

Why are simulated approaches conducted?

Mainly for training and testing.

What is a restricted instrument approach?

An approach that is not authorized for public use but has been approved by TC for restricted use by one or operators

What is a circling approach?

An approach where the pilot flies the instrument approach for one runway then breaks off and lands on another runway once the airport is in view

What are the items in an IFR clearance?

Prefix
Clearance limit
SID
Route
Altitude
Departure/enroute/approach/holding instructions
Special instructions or information
Traffic information

What is a clearance limit?

The point to which an aircraft is cleared

When should you issue a time check when relaying a clearance?

When the clearance contains a a time restriction

What is the maximum permissible delay allowed for delivering a clearance?

3 minutes

What should you do if unable to deliver a clearance within the allowed limit?

Notify the ACC

What should you do if you become aware that an aircraft may not be airborne by their time restriction?

Inform the pilot of the time restriction and ask intentions
Notify the ACC of the pilot intentions
Relay ACC instructions to the pilot

What does APREQ stand for?

Approval request

What are APREQs used for?

Flow control

When an APREQ is in affect what should you do?

Inform pilots
When receiving a clearance request, request ETD and pass to ATC no more than 30 minutes before the ETD
Relay the flow control assigned time to the pilot

When will an ACC inform the FSS of inbound IFR traffic?

at least 15 minutes before the aircraft is expected to establish radio communications

What is an estimate?

The time an aircraft is calculated to arrive over a significant point

How does an estimate differ from an ETA?

ETA refers only to when an aircraft is expected to arrive on the ground
