En Route Block One: Altimeter Setting & Altitude Assignment

Do you need to tell an overhead flight to climb/maintain their current level of flight?

No: the previous controller already did

Where are current altimeter settings obtained from?

Weather reporting stations

What is the barometric pressure reading used to adjust a pressure altimeter for variations in existing atmospheric pressure or to the standard altimeter setting?

Altimeter setting

For all aircraft operating below FL 180, when should the altimeter setting be given while operating within your sector?

At least once

For an aircraft leaving flight levels, what should the altimeter setting given be based off of?

Weather reporting station nearest where the aircraft will descend out of flight levels

If aircraft is arriving to an airport that doesn’t have an approach control facility, when should the altimeter setting be given for their destination?

Within 50 miles

What is the phraseology to indicate if the altimeter setting is over an hour old?

The (facility name) altimeter (setting) more than one hour old

For aircraft operating at & below FL 410 & operating on course degrees magnetic 0-179, what type of cardinal altitudes/flight levels should be assigned & at what intervals?

Odd altitudes; 2000ft (50, 70, 90, FL 350, etc)

For aircraft operating at & below FL 410 & operating on course degrees magnetic 180-359, what type of cardinal altitudes/flight levels should be assigned & at what intervals?

Even altitudes; 2000ft (60, 80, 100, FL320, etc)

For aircraft operating above FL410 on course degrees magnetic 0-179, what type of cardinal altitudes should be assigned & at what interval?

Odd altitudes beginning with FL 410; 4,000ft (FL 410, FL 450, etc)

For aircraft operating at/above FL 410, what is the altitude that they will never receive?

FL 420

For aircraft operating above FL410 on course degrees magnetic 180-359, what type of cardinal altitudes should be assigned & at what interval?

Odd altitudes beginning at FL 430; 4,000ft (FL 430, 470, etc)

In our airspace, when can IAFDOF be given without approval?

Aircraft leaving MCB

What 4 instances can aircraft be given IAFDOF after coordinating with the receiving facility?

1. Traffic conditions

2. Meterological conditions

3. Military aircraft operating on random route

4. Aircraft unable to reach assigned altitude due to aircraft operational limitations

What is the phraseology to ask another sector for a different altitude?

At (next point) (call sign) APREQ (requested altitude)

How should an IAFDOF that was coordinated & approved by the receiving sector be stripmarked?

Underlined & circled in red

For an altitude underlined & circled in red, what does the underline indicate?

IAFDOF

For an altitude underlined & circled in red, what does the circle indicate?

Coordinated & approved

What is the phraseology to instruct an aircraft to go to a certain altitude?

(Aircraft) climb/descend and maintain (altitude)

What is the phraseology to instruct an aircraft to go to a certain altitude after a certain point?

After passing (fix), climb/descend to reach (altitude)

What is the phraseology to instruct an aircraft to maintain altitude until a certain point?

Maintain (altitude) until at OR above/below (point) (new instruction)

What is the phraseology used to tell an aircraft to go over a specified fix at a spcific altitude?

Cross (fix) at OR above/below (altitude)

What is the phraseology to tell an aircraft to climb/descend at pilot’s discretion?

Climb/descend at pilot’s discretion

What is the phraseology to approve a portion of an aircraft’s climb/descent be completed at pilot’s discretion?

Climb/descend now to (altitude), then climb/descend at pilot’s discretion, maintain (altitude)

What needs to be involved for a descent to automatically be considered pilot discretion?

Restriction

After giving an amended clearance, when can the old altitude be used?

When the pilot confirms they have left the old altitude

What is the phraseology to assign more than one altitude?

Maintain block, (altitude) through (altitude)

What should you do if a pilot is unable to accept a clearance for altitude?

Issued revised instruction to ensure positive control and approved separation

What is the phraseology to instruct an aircraft to verify an altitude assignment?

(Aircraft) verify assigned altitude (altitude)

What is the phraseology to instruct an aircraft to verify a flight level assignment?

Verify assigned flight level (flight level)

What is the phraseology to inform an aircraft when to expect climb/descent clearance?

Expect higher/lower in (number) miles/minutes

How should an altitude restriction be preplanned on a strip & what should happen to it once issued to pilot?

Written in red, circled in black

When an amended clearance is given, when can you X out the old altitude & check the new altitude?

When pilot verifies they’ve left the old altitude

What should the pilot do on initial contact (if not done, you should ask them to verify this)?

Verify altitude

Unless needed, when assigning a new altitude, what should you do with the old one?

Don’t acknowledge it
