Flashcards in Unit Operating Instructions Deck (12):

Who gets Cardiff QNH

Departing aircraft passed by Aerodrome (unless aircraft is staying in the visual circuit and using the Cardiff QFE)

VFR arriving aircraft passed by Approach (on first contact Aerodrome passes Cardiff QFE)

IFR arriving aircraft passed by Approach (and QFE if required)


When does RDP show altitude

At or below 6000ft (even in areas where transition altitude is only 3000ft)


Min Stack Levels

Based on lowest QNH of Cardiff and Bristol (combined min stack)

FL90: QNH 943-977
FL80: QNH 978-1013
FL70: QNH 1014+



Cardiff is in Cotswold, close to the boundaries of Portland and Wessex and in the Green 'larger' ASR


SVFR Minima

For departing aircraft (not helicopters) in a control zone - More than 1800m vis and Cloud Ceiling 600ft or more (MATS Part 1)

At Cardiff same minima apply for arrivals into Cardiff or St. Athan


Passing Met Info to (S)VFR Transits

The following should be passed to aircraft prior to entering class D airspace

Met vis is, or falls below 5km
Cloud Ceiling is, or falls below 1500ft

Note: When transiting it is the responsibility of the pilot to determine whether or not the relevant VMC can be complied with

Published VFR Routes Procedures

Defined by VRPs and flown at a max altitude of 1500ft (Cardiff QNH)

For light aircraft ONLY

Include altitude limitation in abbreviated clearance

Pilots must maintain VMC, comply with ANO (low flying rules) and inform ATC of any deviations

ATC should exercise caution in using some VRPs at night - Lavernock Point, Quarry, Nash Point, Coastline

ATC can give full zone clearance instead


Published VFR Departures

", Hold Position, Cleared for a published departure, VFR not above altitude 1500ft, QNH " - issued by tower

When aircraft airborne, Cardiff Tower shall reiterate the level restriction of "not above 1500ft" before transferring to Cardiff Radar

When aircraft contact Cardiff Approach, pilots should be instructed that they are to remain outside CAS once they have departed the Cardiff CTR

8 Published Routes : VFR St Hilary, VFR North, VFR Wenvoe, VFR Flat Holm, VFR South (30+12) VFR Nash Point (30+12). More details MATS Part 2 Page 49


Published VFR Arrivals

Clearance issued by Approach

VFR Nash Point arrival not used when St Athan LFZ active

", cleared for a published Arrival, VFR not above altitiude 1500ft, QNH "

Radar also pass the ATIS and Runway in use

Transfer to Tower after following conditions are met:
1. VFR Block is active
2. ATM is serviceable
3. Aircraft is within 15nm of the CDF
4. Aircraft is displaying an assigned SSR code which tower is aware of

(Radar ATSA will pass full details of the VFR inbound to tower who will ensure that allocated squawk is clearly displayed on the FPS)

Cardiff Tower issue circuit joining instructions and pass the QFE

Non-Published and SVFR arrival clearances will be issued by Radar and co-ordinated with Tower.

9 Routes: (see MATS Part 2 p.50-51)


Single engine VFR aircraft over water?

Try not to impose altitude restriction or remove at the earliest opportunity


Radio Fail Procedure (Light Aircraft, Based at Cardiff, Local Flight)

Select 7600, Route North of Cardiff CAS to the Wenvoe TV mast VRP and complete 2 orbits of the mast at altitude not above 1500ft (Cardiff QNH). Then Follow the published VFR route to the last notified runway in use for landing at Cardiff. Alternative (weather wise), route to Nash Point and make 2 orbits then route East to Cardiff at not above altitude 1500ft (Cardiff QNH) and after passing Aberthaw Power Station proceed to the last notified Runway for landing
