A
  • Unlinked targets
  • CJSs
  • Coast list in full format
  • Altitude readouts (mode C)
  • Current weather data and history
  • VMI
  • Appropriate geographic map
17
Q

What does the term ‘ACKNOWLEDGE’ mean?

A

Let me know that you have received and understood this message.

18
Q

Fill in the blank: An aircraft is deemed to be maintaining a validated altitude when it is within _______ of the assigned altitude.

A

200ft

19
Q

What is the IFR Clearance Format order?

A
  • Prefix/aircraft ID
  • Clearance limit
  • SID
  • Route
  • Altitude
  • Speed
  • Departure, enroute, approach, or holding instructions
  • Special instructions or information
  • Traffic information
20
Q

True or False: An aircraft is considered to have reached an altitude when its altitude has been within 200 ft of the assigned altitude for four consecutive readout updates.

A

True

21
Q

What should be prioritized when assigning altitudes?

A
  • Aircraft carrying a sick or seriously injured person
  • Aircraft already at the requested altitude
  • Leading aircraft when multiple are at the same altitude
22
Q

What is Transition speed?

A

The speed at which a pilot makes the transition between indicated airspeed and Mach number when climbing or descending.

23
Q

How do you express a speed adjustment?

A

As a multiple of 10 knots, based on IAS.

24
Q

What is the general rule for adding speed to indicated airspeed (IAS)?

A

Add 2% of the IAS per 1000 feet of altitude.

25
Q

Fill in the blank: An aircraft is considered to have vacated an altitude when its altitude readout has changed by _______ or more.

A

300 ft

26
Q

What is the purpose of maintaining an effective scan in air traffic control?

A
  • Not forgetting about aircraft
  • Eliminating surprise by unknown aircraft
  • Monitoring previously issued clearances
  • Establishing priorities
