Altimeter Settings

Question 1

Issue the current altimeter setting to …

Answer 1

All en route aircraft operating below FL 180 at least one time while in your airspace, aircraft cleared to descend through the lowest usable flight level, arriving
aircraft approximately 50 miles from the destination airport if the destination is not served by an approach control

Question 2

Lowest usable flight level table.

Answer 2

29. 92+ (180)
30. 91-28.92 (190)
31. 91-27.92 (200)

Question 3

You must let the aircraft know if the altimeter is more then ____ old.

Answer 3

1 hour

Question 4

Appropriate altitudes for direction of flight.

Answer 4

• At and below FL410- east odd, west even
• Above FL410:
East odd 4,000 ft intervals starting with FL410
West odd 4,000 ft intervals starting with FL430

Question 5

When can you assign an IAFDOF altitude?

Answer 5

Traffic conditions prevent it, LOA or FD, meteorological conditions, military aircraft on random routes, exceeds the aircrafts operational limitations

Question 6

What types of clearances allow for descent pilots discretion?

Answer 6

Crossing restrictions, approach clearances and cruise clearances

Question 7

Define Descent Pilots Discretion.

Answer 7

Can climb or descend or level off whenever but cannot return to an altitude once it is left

Question 8

How do you cancel pilots discretion?

Answer 8

Assign a new altitude and state it is an amended altitude

Question 9

What must be done when a route or altitude in a previously issued clearance is amended?

Answer 9

Restate all applicable instructions

Question 10

How do you assign more than one altitude?

Answer 10

MAINTAIN BLOCK (altitude) THROUGH (altitude)

Question 11

What do you do when a pilot is unable to accept a clearance?

Answer 11

Issue revised instructions to ensure positive control and standard separation

Question 12

Controllers are expected to issue ATC clearances which conform with..?

Answer 12

Normal aircraft operational capabilities and do not require last minute amendments to ensure standard separation

Question 13

What do you tell a pilot when you anticipate an altitude change?

Answer 13

Expect climb/descent clearance, or request altitude change from another controller

Question 14

On initial contact or when position reports are received, request a pilot to confirm assigned altitude unless:

Answer 14

The pilot states it on initial contact or you assign a new altitude to climbing or descending aircraft

Question 15

How do you ask for an altitude assignment verification in level flight?…climbing or descending below lowest usable FL?… at or above lowest usable FL?

Answer 15

VERIFY AT…VERIFY ASSIGNED ALTITUDE…VERIFY ASSIGNED FLIGHT LEVEL
