Without a night rating, must be on ground 10min beforehand. Definitions Definitions Principles Aerodrome Lighting • Taxiway lighting is either green centreline or blue sideline lights. • Holding point is amber lighting. • Obstacles have red flashing light at top. Principles • Aerodrome Lighting – Approach End Green – Departure End Red – Edge Lighting White Principles • Aircraft Lighting • CAO 20.18 Appendix V Considerations Go-around • as per day, except 100% instruments. • be aware of somatagravic illusion. Consderations Lighting Failures • landing light failures will be practised • carry portable electric torch for cockpit lighting failures. Considerations • Profile • Wide / Narrow runways
Air Exercise Pre-Flight • Pay Particular attention to lighting • Otherwise as normal • May be dark Start Up • as per day • Use Landing lights to signal intent Taxi • Speed Judgement • Watch out for unlit aircraft / animals Air Exercise Take-Off • conducted 100% visual, as per day • lift-off, climb out on 100% instruments • check +ve RoC, safe IAS, maintaining RWY X-Wind • conducted 75% instruments, 25% visual Downwind • 50% instruments, 50% visual Air Exercise Base • 75% visual, 25% instruments Final • 100% visual • use RWY lighting for approach guidance Landing • RWY lights at shoulder level, power to IDLE • watch end lights to judge FLARE and HOLDOFF Airmanship • Lookout • Remember instrument scans • Trust instruments and be aware of illusions • Correct handover/takeover procedure • Be familiar with aerodrome lighting Review • Review • Definitions – Instrument Scan • Principles – Aerodrome / Aircraft Lighting • Considerations – Go Around – Lighting Failure • Air Exercise • Airmanship • Review
