(1) ATM - SID & STAR

Question 1

What is a STAR? (2)

Answer 1

STAR - Standard Terminal Arrival Route

A designated instrument flight rule (IFR) arrival route linking a significant point, normally on an ATS route, with a point from which a published instrument approach procedure can be commenced

Question 2

What is a SID? (2)

Answer 2

SID - Standard instrument departure

A designated instrument flight rule (IFR) departure route linking the aerodrome or a specified runway of the aerodrome with a specified significant point, normally on a designated ATS route, at which the en-route phase of a flight commences

Question 3

What is the purpose of SIDs & STARs? (7)

Answer 3

• Segregate traffic operating along different routes and traffic in holding patterns
• Provide adequate terrain clearance
• Be compatible with RTF procedures
• Be compatible with NPRs
• Allow for uninterrupted climb and descent
• Allow for the performance of the aircraft (Must cater for the poorest performing)
• Reduce RTF loading for ATC and pilots

Question 4

What is NPR(s)? (5)

Answer 4

NPR(s) - Noise Preferential Routing(s)

• Assisting aeroplanes in avoiding noise-sensitive areas on departure and arrival
• Turns to direct aeroplanes away from noise-sensitive areas located under or adjacent to the take-off and approach flight paths
• Designed to minimise the overall exposure to noise on the ground and at the same time maintain the required levels of flight safety
• Always be incorporated into a SID

Question 5

Composition of a STAR diagram

Answer 5

• Validity Indicator numbered from 1- 9 indicates amendment number
• Basic Indicator – Brandy (BRN) NDB where the ATS route ends (generally a holding facility) and the instrument approach begins
• Route Indicator - Charlie indicates the particular STAR route within a group

Question 6

What information is contains within STAR(s)? (6)

Answer 6

• Standard arrival routes
• Descent Gradients
• Level Restrictions
• Speed Limitations
• Holding Pattern
• Frequency and identity Coding of navigation aids used

Question 7

Composition of a SID diagram

Answer 7

• Validity Indicator numbered from 1- 9 indicates amendment number
• Basic Indicator - Dart (DRT) VOR shows where the ATS route commences and the SID route ends
• Runway Indicator - indicates the SID commences from a particular runway

Question 8

What information is contains within SID(s)? (6)

Answer 8

• Standard Departure routes
• Frequency and identity coding of navigation aids used
• Climb gradients
• Level restrictions
• Speed limitations
• Transition altitude
