Which instrument is used by the pilot during poor visibility?
The attitude indicator is a primary instrument for instrument flight and is also useful in conditions of poor visibility. Pilots are trained to use other instruments in combination should this instrument or its power fail.
What is low visibility operations?
Low visibility procedures (LVP) means procedures applied at an aerodrome for the purpose of ensuring safe operations during lower than standard category I, other than standard category II, category II and III approaches and low visibility take-offs. (
What is the difference between pilotage and dead reckoning?
Pilotage is the art of knowing where you are by reading a map and comparing it with the surrounding terrain and landmarks, while dead reckoning is the art knowing where you currently are by using a compass, your ground speed, a clock and an initial known position.
What causes low visibility?
Visibility distance is reduced by fog and heavy precipitation, as well as wind-blown snow, dust and smoke. Low visibility conditions cause increased speed variance, which increases crash risk.
What to do when taxiing in low visibility?
Give detailed CTAF radio reports of your location and progress during taxi. The FAA requires the commissioning of an FAA-approved Low Visibility Operations (LVO) Surface Movement Guidance Control System (SMGCS) operation for all new Category III ILS supported runways. This system provides pilots extra visual references to follow during taxi.
Can a plane take off in low visibility?
The FAA says, “pilots and aircraft operators should be constantly aware that during certain low visibility conditions the movement of aircraft and vehicles on airports may not be visible to the tower controller. This may prevent visual confirmation of an aircraft’s adherence to taxi instructions.”

What should a pilot do in low visibility?
This system provides pilots extra visual references to follow during taxi. When the visibility is below 1,200 RVR, pilots should comply with ATC ground instructions while referencing a SMGCS chart for lighting details and guidance.
