A
  • When the AC reaches a position from which it appears that a successful approach cannot be completed
  • If the AC is not visible on the situation display for any significant interval during the final 2NM (4km) of the approach
  • If the position or ident of the AC is in doubt during any portion of the approach
  • In all cases the reason for the instruction or advice should be given to the pilot.
105
Q

What is allowed if an obstruction is within Zone 1?

A
  • No approach clearance

- Take off allowed away from obstruction only

106
Q

What is allowed if an obstruction is within Zone 2?

A
  • OCA increased by 200’ for an ILS approach
  • OCA increased by 300’ for a NPA
  • Take off allowed
107
Q

What is allowed if an obstruction is within Zone 3 - Departure surface?

A
  • No approach clearance

- No take off

108
Q

What is allowed if an obstruction is within Zone 3 - Approach surface?

A
  • No approach clearance

- Take off away from obstruction only

109
Q

What are obstacles in the protection zone defined as?

A
  • Obstructions during construction work, normally planned well ahead or possible restrictions can be foreseen
  • Suddenly occurring temporary obstructions may require immediate action
110
Q

How can the required obstacle clearance be achieved with an obstruction within the protection zone?

A
  • Shortening the RWY by a displaced threshold

- Zones 1 2 and 3 will be recalculated

111
Q

If a displaced threshold is established due to an obstruction, what are pilots to be informed about?

A
  • Type and position of the obstruction
  • Details about the reduced RWY length
  • Change in OCA
112
Q

What are the most common types of RWY incursion?

A
  • Departing AC enters RWY contrary to ATC clearance
  • AC crosses a RWY after landing, contrary to ATC clearance
  • ATC issue taxi clearance in conflict with another AC clearance
  • ATC clear something onto a RWY in error, or due to misjudgement
  • Towed AC crosses a RWY contrary to ATC clearance
113
Q

How could an ATCO induced situation contribute to a RWY incursion?

A
  • Poor vis may hinder ATCO’s judgement
  • Not verifying the read back
  • Losing traffic situation or misjudging (or assuming) the location of the AC or vehicle
114
Q

How could a flight crew induced situation contribute to a RWY incursion?

A

-Disorientation, especially at an unfamiliar airport

115
Q

How could a driver related situation contribute to a RWY incursion?

A
  • Lack of sensitisation
  • Lack of training
  • Loss of position
116
Q

List RWY incursion contributory factors

A
  • Poor vis
  • AD design
  • Conditional clearances
  • Simultaneous use of intersecting RWYs
  • Late issue of or late changes to departure clearances
  • Use of non standard phraseology
  • Concurrent use of more than one language for ATC comms
  • English language competance
  • ATC and pilot workload
117
Q

What measures can be taken to reduce RWY incursions?

A
  • Use of standard phraseology
  • Maintaining situational awareness by the tower controllers, of AC and vehicle movements near to active RWYs
  • Maintaining situational awareness by flight crews and others using the manoeuvring area
  • Presence of ICAO standard RWY markings and TWY surface markings and signs
  • Identification of hot spots
  • Training for airside vehicle drivers
