FAA Aircraft Dispatcher Practice Exam

When determining if an alternate airport is needed, what factors must be considered?

1. Aircraft age and weather conditions only

2. Potential low ceilings and visibility at destination

3. Flight crew experience and passenger count

4. Fuel efficiency ratings and aircraft weight

The correct answer is: Potential low ceilings and visibility at destination

When determining if an alternate airport is needed, one of the key factors to consider is the potential for low ceilings and visibility at the destination airport. This is crucial because the ability to land safely depends heavily on the weather conditions at the planned arrival airport. If the weather forecasts predict low ceilings or visibility that does not meet the minimums for the approach, it may not be safe to proceed directly to that airport. In such cases, an alternate airport can provide an alternative landing option should the conditions at the destination deteriorate further or prove unsuitable for landing upon arrival. Regulatory requirements often necessitate planning for such contingencies to ensure passenger safety and operational integrity during flight. Thus, assessing the likelihood of low ceilings and visibility is essential in making a well-informed decision about the need for an alternate airport.
