Q

TAS

A

TAS (TRUE AIRSPEED) - The airspeed of an aircraft relative to undisturbed air. It is used primarily in flight planning and the enroute portion of flight. When used in pilot/controller communications, it is referred to as “true airspeed” and not shortened to “airspeed.”

TAS is the speed shown on an FDE

TAS can be used for determining potential future conflicts as well as a guideline for the performance capabilities of aircraft (by their filed TAS)

Q

TC AIM RAC 11.1 Adherence to Mach Number
**

A

Within CDA, aircraft shall adhere to the Mach number assigned by ATC, to within 0.01 Mach, unless approval is obtained from ATC to make a change or until the pilot receives the initial descent clearance approaching destination. If it is necessary to make an immediate temporary change in the Mach number (e.g. because of turbulence), ATC shall be notified as soon as possible that such a change has been made.

If it is not possible to maintain the last assigned Mach number during en route climbs and descents because of aircraft performance, pilots shall advise ATC at the time of the climb/descent request.

If the type of separation or the minimum used to separate aircraft cannot be maintained….

A

If the type of separation or the minimum used to separate aircraft cannot be maintained, take action to ensure that another type of separation exists, or another minimum is established, before the current separation becomes insufficient.

Q

On exam: question will be, why would you assign speeds to an aircraft*

A

If required to achieve or maintain required spacing or to minimize vectoring, instruct a pilot to adjust the aircraft’s speed.

Note: avoid repetitive and constant speed changes unless they are required because of traffic flow, traffic levels, pilot workload or airspace design

Q

Express the speed adjustment using either of the following methods:

A
  • As a multiple of 10 knots, based on IAS
  • If the aircraft is a turbojet operating in high-level airspace, as a Mach number

Note: Aircraft complying with speed adjustments are expected to maintain a speed within 10 knots of the specified speed

11
Q

When making speed adjustments, use the guidelines provided in the table below.

MINIMUM ASSIGNABLE SPEEDS

A

MINIMUM ASSIGNABLE SPEEDS:

Distance to destination: 20 miles or more
- 10000 ASL and above: 250 IAS
- Below 10000 ASL: 210 IAS

Distance to destination: less than 20 miles
- TurboJet
150 IAS - only when required for spacing on final approach
160 IAS - preferred when assigning a speed to cross the final approach fix
- Propeller - 120 IAS

You may assign speeds that are lower than those specified only after coordinating with the pilot.

“CAN YOU MAINTAIN (SPEED)”
“ARE YOU ABLE TO MAINTAIN (SPEED)”
“WHAT IS YOUR MINIMUM APPROACH SPEED?”

***For voice rec in the sim “Are you able Mach .82”. Do not say speed or else you will get Indicated air speed

Some aircraft may be unable to maintain the specified speed. Turbojet aircraft that are less than 10 miles from the runway and are conducting straight in approaches in IMC should not be asked to maintain a speed higher than 160 knots

Q

Do not approve a speed over…

A

Do not approve a speed over 250 knots IAS below 10000 feet above sea level, but acknowledge a pilot who informs you of a requirement to operate above the CARs-regulated speed limitations for minimum safe speed requirements

If a pilot reports or operates at a speed over 250 knots below 10000 feet above sea level and does not state that it is for minimum safe speed, inform the ACC shift manager.

Pilot: “BURNER THREE EIGHT MINIMUM SAFE SPEED THREE ZERO ZERO KNOTS”
ATC: “BURNER THREE EIGHT ROGER”

A

(a) BELOW 10,000 ASL at more than 250 KIAS; or
(b) below 3 000 ft AGL within 10 NM of a controlled airport and at more than 200 KIAS, unless authorized to do so in an air traffic control clearance.

Exceptions (dont need to know this)
(a) A person may operate an aircraft at an indicated airspeed greater than the airspeeds referred to in (a) and (b) above where the aircraft is being operated in accordance with a special flight operations certificate – special aviation event issued under CAR 603
(b) If the minimum safe speed, given the aircraft configuration, is greater than the speed referred to in (a) or (b) above, the aircraft shall be operated at the minimum safe speed.

Q

Sequencing Mental Model

A

1) Choose your order
2) Assign speeds
3) If speed alone doesn’t work, vector
4) Monitor

21
Q

if you hand off an aircraft to an adjacent sector, aircraft entrail of each other must be

A

handed of with 10 miles separation that is constant or increasing if they are at the same altitude

This is true for the entire course

22
Q

Use of the word “TO” in speed assignments….

A

may be omitted where it is reduntant or could be mistaken for the number TWO

23
Q

MATS ACC > ATS Surveillance > Speed Assignments > Issuing Speed Reductions and Simultaneous Descents

A simultaneous descent and speed reduction can be…

A

A simultaneous descent and speed reduction can be a difficult manoeuvre for some types of turbojet aircraft. It may be necessary for the pilot to level off temporarily and reduce speed prior to descending. Specifying which action is to be accomplished first removes any doubt the pilot may have concerning controller intent or priority.

REDUCE [SPEED] [TO] (number) KNOTS [OR LESS], THEN DESCEND [TO] (altitude)

DESCEND [TO] (altitude), THEN REDUCE [SPEED] [TO]
( (number) KNOTS / MACH (number) ) [OR LESS]

DESCEND [TO] (altitude), THEN REDUCE [SPEED] BY
( (number) KNOTS / MACH (number) )

24
Q

You may instruct a pilot to fly at slower speeds. Do not…

A

Do not specify the minimum aircraft speed when a higher speed would suffice.

25
Q

Issuing a Maximum speed

A

MAINTAIN [SPEED] (number) KNOTS OR LESS

MAINTAIN [SPEED] MACH (number) OR LESS

DO NOT EXCEED [SPEED] (number) KNOTS

DO NOT EXCEED [SPEED] MACH (number)

26
Q

when a speed adjustment is no longer necessary

A

Except when the aircraft has been cleared for an approach, advise the aircraft to resume normal speed when a speed adjustment is no longer necessary.

RESUME NORMAL SPEED
RESUME PUBLISHED SPEED

Resume normal speed does not cancel published speed restrictions

27
Q

SAME TRACK

  • KNOW THIS
A

In the application of separation, expression used by ATC to indicate identical tracks or tracks that converge or diverge at an angle of 1° to 44° inclusive.

28
Q

if it appears the aircraft is not operating in accordance with a previously assigned speed instruction

A

Unless the pilot advises they are unable to comply, promptly restate a speed assignment if it appears the aircraft is not operating in accordance with a previously assigned speed instruction.

29
Q

Provide air traffic services to aircraft on a _____ basis

A

Provide air traffic services to aircraft on a “first come, first served” basis

Exceptions to “first come, first served” are permitted when they increase overall efficiency and reduce the average delay.

(Exceptions in another card)

30
Q

Factors that could affect traffic sequence include:

(exceptions to first come first serve basis)

*know these

A
  • The type of approach intended
  • The types of aircraft and their relative performance
  • Any specified minimum departure interval between takeoffs
  • The routes to be followed after takeoff
  • Wake turbulence separation minima
  • Aircraft subject to ATFM
31
Q

Same Strata

A

Aircraft that are within four thousand feet or less of each other are in the same strata as far as IAS and Mach are concerned. When using speed control, it is important to keep aircraft in the same strata, otherwise you will see appreciable differences in the ground speeds of the two aircraft, even though they have been assigned the same speed.

32
Q

As a rule, jet aircraft at idle thrust will…

A

As a rule, jet aircraft at idle thrust will take about 1 NM to lose 10 knots, and 3 NM to lose 1000 feet.

Therefore, it will take 11 NM to slow an aircraft from 300 knots at 12 000 feet to 250 knots at 10 000.

33
Q

List the ways a speed can be adjusted

A
  • You may instruct a pilot to fly at a specific speed
  • Reduce to a Specific Speed or Less
  • Increase to a specific speed or greater
  • Reduce Speed by a specific value
  • Increase Speed by a specific Value
  • Issuing a minimum speed
  • issue a maximum speed
34
Q

How to roughly estimate TAS

A

For every 1000 feet of altitude, add 2% to the IAS (not compounding)

35
Q

An approach clearance supercedes…

A

An approach clearance supercedes a speed adjustment request, and pilots are expected to make their own speed adjustments to complete the approach. if you require aircraft to adjust speed while on the approach, restate the request
