L3 ATC Procedures

Flashcards based on ATC Procedures lecture notes.

What is the proper format for a test radio transmission?

The identification of the aeronautical station being called, the aircraft identification, the words 'Radio Check', and the frequency being used.

What is the readability scale used to classify radio transmissions?

A scale from 1 to 5, with 1 being unreadable and 5 being perfectly readable.

What is the simplest way to make an initial call on a radio frequency when departing an airfield?

Call sign of the aeronautical station, then the aircraft's full call sign.

What three important pieces of information should be communicated in an initial call from an aircraft?

Who you are, where you are, and what you want.

What does it mean when ATC give a departure clearance to depart 'straight ahead' after take-off?

To track the runway extended center-line after take-off until a specified point/level

How will ATC emphasize that take-off needs to start without delay?

ATC will use the word 'immediate'.

What is expected of an aircraft when the pilot accepts an 'immediate take-off' clearance at a runway holding point?

The aircraft is expected to taxi onto the runway and take-off without stopping.

What is the specific order and format for issuing a conditional clearance?

The call sign, the condition, the clearance, a reiteration of the condition.

What does 'climb' or 'descend' mean in ATC instructions?

To climb or descend to and maintain the cleared level.

What is the purpose of an alerting service?

Notify appropriate organizations if an aircraft is in need of search and rescue aid.

How often is an aircraft required to make radio contact with the ATSU when operating on the same frequency for a long period of time?

Between 20 to 40 minutes.

What essential information should an airfield ATSU pass to an arriving flight?

What are the two standard locations in the visual circuit for making a position report?

Downwind and final.

What information is included in a clearance to land?

Runway designation and the surface wind.

What is to be expected if an aircraft is cleared to continue the approach, pending a further clearance?

A further clearance, either to land or to 'go around'.

What happens during a visual go-around?

Breaks off the approach and climbs back to the circuit height.

What is the 'Live Side' of the circuit?

The side of the runway in use where the circuit pattern is active.

What should be reported to allow other pilots and the ATSU to plan accordingly?

That an approach is planned to finish with a go-around.

What happens during a touch and go?

Aircraft lands, continues rolling, and makes another take-off without stopping.

When is it helpful to let the ATSU and other pilots know you are going to do something?

When planning a 'full stop' landing

What is the overriding order of priorities for a pilot to remember?

Aviate, Navigate, Communicate.

What should a pilot do if what ATC is asking is not possible?

Inform ATC that they cannot comply with the clearance.

What happens on departure when operating around larger aircraft regarding wake turbulence?

ATC will not normally issue a take-off clearance.

What may ATC do if a light aircraft is making a visual approach behind a larger aircraft?

Warn of the danger of wake turbulence.

What is the name when the aircraft should track the runway extended centre-line after take-off, until the specified point/level?

Extended Centreline

In the situation where ATC may require an aircraft to line-up on the runway and hold position awaiting clearance to take-off, what instructions may they give?

ATC may use the instruction 'wait'

During the 'en-route' phase of the flight, what kind of airspace may a VFR flight operate in?

The flight may operate in different classes of airspace and receive different levels of service from different Air Traffic Service Units

When are the words 'take-off' first used?

The words 'take-off' are first used only when an aircraft is cleared for take-off by ATC.

What phrase should never be used?

Under no circumstances should the phrase 'ready for take-off' be used.

What other term can be used to describe the circuit?

The circuit is also sometimes referred to as the 'pattern'.

When the aircraft is positioning onto the dead side of the runway, what position is it on?

The position is opposite to the established circuit pattern.

During the en-route phase, who can issues clearances and instructions?

Clearances and instructions in the en-route phase of a VFR flight can only be issued by Air Traffic Control units.

What action will the ATSU may instruct the aircraft to do if they wants the aircraft to move off the runway as quickly as possible?

Expedite vacating

When are conditional clearances issued?

Conditional clearances are only issued when the aircraft or vehicles involved are visible at all times to both the controller and the pilot.

Why is important about a touch and go?

The ATSU and other pilots need to know if this is the intention.

On arrival at the destination, what information will it be necessary to obtain?

The runway in use.

Why may ATC issue a 'conditional clearance'?

To expedite traffic flow.

On arrival at the destination, what kind of joining instructions will it be necessary to obtain?

Any specific joining or routing instructions

On arrival at the destination, what wind information will it be necessary to obtain?

The surface wind.

On arrival at the destination, what pressure setting will it be necessary to obtain?

The pressure setting (QNH and/or QFE).

On arrival at the destination, what traffic details will it be necessary to obtain?

Details of any traffic

Why would the aircraft be instructed by ATC to extend the downwind leg?

To ensure separation and permit another aircraft on final to land

When operating around larger aircraft why what consideration becomes important?

The avoidance of wake turbulence becomes an important consideration

In addition to the wake turbulence warnings, what else may ATC add?

ATC may also add recommended spacing in nautical miles between aircraft, based on their wake turbulence categories

If an aircraft remains on the same frequency for a long period of time without making any transmissions, what may happen?

The ATSU may become concerned that contact has been lost.

What transmission is one option to make when the aircraft is required to make radio contact with the ATSU between 20 to 40 minutes after the last transmission?

The aircraft's call sign and the words 'operations normal'.

What reply is expected to an 'all stations' transmission?

No reply.

What is the alerting service?

A service provided to notify the appropriate organisations if an aircraft is in need of search and rescue aid, and assist such organisations as required

If trying to comply with the clearance would involve unacceptable risk, what should the pilot inform ATC?

That it cannot comply with the clearance

The side opposite to the established circuit pattern.

The side opposite to the established circuit pattern.

What approach is lined up to the landing runway and within four miles of the runway?

Final Approach

How may ATC emphasize a pilot's option to refuse an immediate take-off clearance?

ATC may emphasize this by confirming an alternative option.

Why might ATC issue a conditional clearance?

To expedite traffic flow.

After a climb and descent instruction, what should you make sure to do?

Maintain the cleared level.

What should a pilot do when he or she has any uncertainty about the conditional clearance?

They should not hesitate to request clarification of any information, clearance or instruction if he or she has any uncertainty.

As a default, within European airspace an aircraft receiving either an Air Traffic Control or Flight Information Service is also receiving what service?

Alerting service.

When is it helpful to make a transmission when doing a series of touch and goes?

To let the ATSU and other pilots know when planning a 'full stop' landing.

What purpose does the ATSU instruction Diamond VN serve?

To expedite vacating off the runway.

What will vary with circumstances when departing?

The format of the initial call from an aircraft wanting to depart the airfield.

How must the departure clearance be dealt with?

In accordance with the read-back rules, such a departure clearance must be read-back in full.

To emphasise that the aircraft has not been given take off clearance what will ATC use?

ATC may use the instruction 'wait' to emphasise that the aircraft has not been cleared to take-off.

Who needs to know if a pilot is planning a touch and go?

The ATSU and other pilots.

Who may initiate a go-around?

ATC may also initiate a go-around.

To maintain traffic flow and separation, what may ATC specify?

ATC may specify an order for landing, and all aircraft are required to maintain that order.

What are some examples of instructions passed to an aircraft in relation to where to leave or vacate the runway?

Take the next left or take the next convenient right

What will happen regarding wake turbulence on departure?

On departure ATC will not normally issue a take-off clearance until the appropriate wake turbulence separation has been achieved.

If a light aircraft is making a visual approach behind a larger aircraft, what may happen?

ATC may again warn of the danger of wake turbulence if a light aircraft is making a visual approach behind a larger aircraft

If an aircraft remains on the same frequency for a long period of time without making any transmissions, what is the aircraft required to do?

To make radio contact with the ATSU between 20 to 40 minutes after the last transmission
