3 rotor-diameters

Question 14

Land after criteria (5)

Answer 14

1. During daylight hours
2. Runway is long enough for safe separation & no evidence to indicate breaking action may be adversely affected
3. Proceeding A/C not required to backtrack to be able to vacate the runway
4. ATCO is satisfied the landing A/C will be able to see proceeding A/C has landed (clearly and continuously) until it’s vacated the Runway
5. Pilot of following A/C is warned (Responsibility for ensuring adequate separation rests with the pilot of the following aircraft)

Question 15

Multiple line-up clearance (5)

Answer 15

1. During daylight hours
2. All A/C are continuously visible to the ATCO
3. All A/C are on same frequency
4. Pilots advised of the number ahead in departure sequence & position / runway from which they will depart
5. The physical characteristics of the runway do not render preceding aircraft in the departure sequence invisible to succeeding aircraft on the same runway

Question 16

Multiple Runways in use – Before commencing (3)

Answer 16

1. APC is advised
2. No WIP or taxiing A/C affects either runway
3. Sufficient Info’ / restrictions have been given or placed on Heli traffic

Question 17

Multiple Runways in use – When in use (5)

Answer 17

1. All traffic is suitably advised and adequate traffic information is passed as necessary
2. The designator of the runway to be used is transmitted with each take-off and landing clearance
3. The flight data display clearly shows multiple runways are in use
4. Pilots are given their number in sequence, together with the intentions of the aircraft ahead
5. Any Multi-Line up’s are IAW MATS Pt 1

Question 18

Noise Abatement Procedure – Runway 09 (Jet departures only)

Answer 18

Climb SA to 1400ft (QNH)

Question 19

Noise Abatement Procedure – Runway 27

Answer 19

1. Right turn 30° (After passing upwind end of runway)
2. Track 294° (Magnetic) to avoid church in Down Hatherley
3. Jet A/C to climb through 1400ft (QNH) before any turn

Question 20

Noise Abatement Procedure – Runway 04

Answer 20

Climb SA until passing Staverton Village (1.1 DME)

Question 21

Answer 21

No left turns until passing Chosen Hill (1.2 DME)

Question 22

FW / Heli CCT heights (4)

Answer 22

1. Jet – 1500ft QFE / 1600ft QNH
2. FW – 1000ft QFE / 1100ft QNH
3. Heli – Not above 750ft QFE
4. Bad Wx – Not Below 600ft QFE

Question 23

Co-ordination with Approach (MATS Pt 1 & 2). (11)

Answer 23

MATS PT 1:
1. Departing IFR Flights
2. Arriving A/C which make their first call on TWR Frequency

MATS PT 2:
3. Notify APC of any intended permanent or temporary change of runway in use and departures from any runway not in use
4. Notify APC when multiple runways are in use
5. Notify APC when the fixed wing/helicopter circuit is active
6. Establish transfer of control points for arrivals
7. Obtain clearance for IFR departures
8. Transfer all deps to APC as soon as possible, after pertinent traffic information has been passed
9. Not to allocate any levels above 1500 FT within the ATZ without co-ordination
10. Acknowledge APC upon notification of base turn complete or final approach track
11. Advise APC of actual time of departure for all IFR departures

Question 24

What are the Transfer of Control points? (4)

Answer 24

• OVH joins – 3 nm
• DCT joins – 5 nm
• FAF – 5 nm
• Other Instrument Traffic – 4 nm

Question 25

What are the periods of display for AGL? (9)

Answer 25

Question 26

Student considerations (MATS Pt 2). (3)

Answer 26

1. All instructions to be passed at a reasonable pace, kept simple and as far as practicable
   (IAW CAP 413 and MATS Pt1)
2. When re-joining, their number in the landing sequence is to be passed as soon as possible - When in the circuit, delaying action shall be passed on the downwind leg, or, in exceptional circumstances, at the commencement of the base leg only
3. Once the A/C has turned base or commenced its final descent it should be regarded as committed to land and should only be permitted to do so. (The aircraft is not to be instructed to do any other manoeuvre except for a go around)
