Ensure that the runway is (or will be) free of all known obstacles, such as vehicles, before _______________.
An aircraft departing commences its takeoff, OR an aircraft arriving crosses the threshold.
Which instruction must be read back by all vehicles
Hold short
What word is used when the destination is a runway/taxiway to permit the vehicle to proceed?
ONTO (instead of TO)
Staff 20 has just called requesting to go to the firehall. He is at the MAP, and JZA453 (DH8C) is on a 4 mile final runway 32. What do you say to Staff 20?
ST20, NEGATIVE, proceed via alfa, hold short runway 14, aircraft on final
(Ident, NEGATIVE, instructions, reason)
What must instructions not be dependent on?
Vehicle instructions must not be conditional or depended on aircraft movements
When must the specialist instruct the ground traffic to leave the intended runway, taxiway, or runway protected area?
At least 5 min prior to the ETA, or before a departing aircraft enters the manoeuvring area.
Note: this means the INSTRUCTION must be issued 5 min prior, not that the vehicle must be removed 5 min prior.
You may authorize ground traffic to operate within 5 minutes of the ETL, or prior to an aircraft ready for takeoff, provided ____________ (5 things)
- Runway will be free of obstacles
- Can maintain a visual watch of ground traffic AND the final approach leg or segment of the aircraft
- Positively identify aircraft position
- Completed PRIOR to aircraft passing FAF (IFR) or being on final (VFR)
- Other factors considered (performance, runway conditions, etc)
Define Final Approach Leg (AKA Final Leg)
A flight path extending from the end of the base leg in the direction of landing to and along the extended centerline of the runway (or landing path) to the threshold of the landing runway (or landing path).
Define Final Approach Segment
That part of an instrument approach procedure from the time the aircraft:
A: completes the last procedure turn or base turn, where one is specified,
B: crosses the final approach fix, waypoint, or point, OR
C: intercepts the last track specified for the procedure until it reaches the missed approach point.
It is in this part of the procedure that alignment and descent for landing are accomplished.
What must be done if you authorize ground traffic to cross the intended runway, assuming an IFR aircraft has passed the FAF or a VFR aircraft is established on final?
A. M405.4 requirements must be met (prior to an aircraft commencing its takeoff or landing aircraft crossing the threshold)
B. M423.3 must be met (ensure you can maintain visual watch of ground traffic and are satisfied it will remain in sight, and maintain visual watch of the final approach leg/segment of the IB aircraft, and you positively identify the aircraft’s position, and you consider the type and performance of ground and air traffic, the runway condition, and other factors that may have an impact.)
C. Coordinate with the aircraft (ACA121, truck crossing at bravo)
What is the phraseology to instruct ground traffic to leave the manoeuvring area?
Vehicle Identification (Truck 81) Leave / Exit / Get Off (Exit) Manoeuvring surface (Runway 14) AT location (at Alfa) AND REPORT OFF
In areas where the specialist can’t see the ground traffic leaving the manoeuvring area, what must the specialist instruct the ground traffic to do?
Report Off
What words shall be used to expedite the movement of ground traffic?
Without Delay
(Note: Simulator Command may require “Expedite” - as per Bill)
What is the difference between asking a vehicle operator to leave the runway “without delay” and “immediately”?
Without delay will have them proceed to the nearest suitable taxiway or adjoining runway or service road, immediately is used to have them exit the runway at the nearest edge point.
How must a specialist instruct multiple vehicles to leave the runway at the same time?
- Broadcast the instruction
- Instruct each vehicle to respond in turn, if appropriate
(ATTENTION ALL VEHICLES, EXIT RUNWAY ZERO NINE AND REPORT OFF. FOLLOWING VEHICLES RESPOND: TRUCK EIGHT ONE, STAFF TWO ZERO, BLOWER THREE FOUR.)
What must a specialist do with ground traffic if traffic is in the aerodrome circuit for which no prior information is received, and communication cannot be established?
remove ground traffic from appropriate runway protected areas
What shall a specialist do if aircraft and ground traffic cannot operate safely on the same taxiway at the same time?
Instruct ground traffic to leave the intended taxiway
(note this applies when taxiway is too narrow for the wingspan and the vehicle, AND/OR when there is a risk of damage to the vehicle by flying debris
When can a specialist omit informing aircraft and ground traffic of each other when both are operating on the same taxiway?
you have approved or restricted the movement of the ground traffic such that it will not operate within the aircraft’s intended route AND you can see the traffic on the taxiway and are satisfied that it will remain within sight.
How far behind a departing aircraft must ground traffic be if operating on the same runway?
200 feet (60 metres)
What is the radius of the ILS critical area, and what vehicles can be in this area?
500 feet (150 metres) Tech vehicles ONLY
These restrictions apply when the ILS is being used or may be used (enroute aircraft in bay) by IFR aircraft.
A vehicle is in the ILS critical area. Should a VDS be in the strip board, and if so in which bay?
Yes, and ACTIVE.
The exception is TECH vehicles. A tech vehicle in the ILS critical area does NOT require a VDS in the active section.
A vehicle may be instructed to operate on a single runway and through a runway intersection repeatedly for repetitive ground traffic operations. What phraseology would be used to approve this?
UNTIL FURTHER ADVISED
Define Runway Incursion
Any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for landing and takeoff of aircraft
What must be done if a runway incursion takes place?
After resolving the incursion a log entry is required
Example: ST20 CROSSED RWY09/27 WITHOUT AUTHORIZATION. NCM/BL ADZ 1910 DC
When should a specialist issue advance notification of inbound aircraft to ground traffic?
if requested be vehicle operator, or when the specialist judges it to be appropriate.
(May be particularly useful for personnel conducting crack filling or snow removal)
To whom must a specialist issue anticipated aircraft traffic information, including low approach, in advance?
To ground traffic that will not be in continuous radio communication with the specialist.
note: the above is the MUST, there are other times when the specialist could do so, such as extended delays.
What is the phraseology for requesting a readback of hold short instructions if they were not readback by the ground traffic?
READBACK HOLD INSTRUCTIONS
When the MF is out of service, what should the specialist do?
Restrict movement of ground traffic on the manoeuvring area or within the RPA. As a minimum MUST put into operation the features of the agreement with the APO dealing with the movement of non-radio equipped ground traffic.
If no contact can be achieved with a vehicle on the runway, and there is an inbound aircraft, what must the specialist do?
Contact aircraft and inform them “WE HAVE NO CONTACT WITH A VEHICLE ON RUNWAY >. MAY WE BLINK THE RUNWAY LIGHTS OR DO YOU PREFER TO MAKE A LOW PASS PRIOR TO LANDING?”
If pilot approves blinking lights, blink lights.
An alternate solution is dispatching another vehicle to get the first vehicle off.
When must a specialist inform aircraft of ground traffic
when the specialist does not expect the ground traffic to be off the intended runway, taxiway, or runway protected area before the aircraft lands or begins to taxi onto any portion of the intended taxiway or runway
A specialist cannot establish communication with an inbound IFR aircraft, and cannot obtain an ETL from the ACC. What must the specialist do?
Communication is later established. What can the specialist do?
Instruct all ground traffic to leave runways and runway protected areas at least 5 minutes before the last known estimate.
Authorize ground traffic that has been removed from runways o RPAs back onto the runway or RPA IF the position of the aircraft is established OR it is apparent that the aircraft will not be landing at the aerodrome, AND IF there is no likelihood of collision between an aircraft and ground traffic.
Staff 20 is on Runway 32 replacing a runway light. Jazz 452 calls and is taxiing for departure runway 32. You have passed him his clearance, but Staff 20 has told you he only needs 1 more minute to clean up his tools and get off the runway. What do you say to JZA452?
Jazz 452, Vehicle on Runway 32 expected to be off in 1 minute, will advise when off.
What must a specialist do if a pilot plans to do a low approach, in regards to ground traffic?
Inform aircraft of any ground traffic and other aircraft expected to be on the intended runway or within the runway protected area when the aircraft will commence it’s low pass above the runway.
Advise ground traffic and other aircraft on or near the intended runway of the aircraft about to do the low approach. (STAFF 20, BEECH 200 ON LOW APPROACH RUNWAY 27)
What is the phraseology to report ground traffic “off”
Example: Grader 23 was on Runway 32 with an aircraft on downwind and you informed the aircraft that the vehicle would be off in 1 minute. Grader 23 is now on Alfa
IS OFF
Example
GRADER IS OFF RUNWAY THREE TWO
When must helicopters be informed of ground traffic?
When ground traffic will be operating in close proximity or might affect the safety of the flight, or whose safety might be affected by the helicopter.
