How to keep it safe when flying in fog ✈️
Operating in low visibility can be challenging and presents a variety of threats.
However, thanks to robust operating procedures, we can safely operate in very poor visibility and do so on a regular basis.
Maintaining situation awareness whilst taxiing around complex airports is paramount.
There have been instances in the past when aircraft have lined up on an incorrect runway or mistaken the runway edge lights as the centreline.
To prevent these errors from occurring again, airlines have developed robust operating procedures to help pilots depart safely.
For example, to ensure that the aircraft is lined up on the centreline of the correct runway, we tune the ILS frequency.
This provides electronic centreline guidance to the pilots, who must confirm that the localiser pointer is centred on the displays.
If departing from the threshold of the runway, we can also visually check the runway identifier painted on the runway - eg “22”
In more recent years, aircraft have been fitted with additional systems to help prevent runway misidentification.
An example of this is RAAS - Runway Awareness and Advisory System.
This uses a variety of aircraft systems to identify which runway the aircraft is on, as well as provide additional information, such as runway distance remaining etc.
It’s by using these comprehensive procedures that the safety of the operation can be maintained 💪✈️
