Runway protection: No aircraft or vehicle is allowed to enter the runway or ILS critical area without explicit clearance. Controllers avoid issuing line-up clearances too early.
Use of stop bars: Red stop-bar lights at runway holding points remain on and are only switched off when ATC clears an aircraft to cross or enter the runway.
Increased spacing: Arrival and departure spacing may be increased to allow more time for vacating the runway and for radar identification.
Reduced taxi complexity: Controllers may use simpler, shorter taxi routes and restrict certain taxiways to avoid confusion.
Approach minima: Only aircraft and crews approved for low-visibility operations (e.g. CAT II or CAT III) can land when RVR is very low. Others must divert or hold until conditions improve.
Taxi discipline: Pilots must taxi slowly, follow the cleared route exactly, and stop at all stop bars and holding points unless cleared otherwise.
Checklists and briefings: Additional or extended briefings are required for low-visibility take-offs and approaches, including go-around and missed approach planning.
Lighting and equipment: Use of all available external lights, anti-collision lights, and internal aids such as moving maps or surface radar displays, if installed.
Check take-off minima: Confirm that reported RVR or visibility meets or exceeds the published minima for your runway and aircraft type.
Use the correct runway: LVP may limit departures to a specific runway equipped for low-visibility operations.
Align carefully: Use centerline lights or markings to ensure correct runway alignment before applying take-off power.
Maintain centerline: Use visual cues and, if available, instruments such as heading indicator and flight director to stay on the centerline during the take-off roll.
Be prepared to reject: In case of doubt about runway alignment, instrument indications, or aircraft performance, be ready to reject the take-off while there is sufficient runway remaining.
