Final answer:
In aviation, 'Land as Soon as Possible' means finding the nearest safe landing site, while 'Land as Soon as Practicable' means to land at the first suitable site without unnecessary delay. The pilot has discretion in choosing the landing site and considering other factors.
Step-by-step explanation:
In aviation, the phrase 'Land as Soon as Possible' (LASP) means to find the nearest suitable landing site as soon as practical, taking into account factors such as weather, terrain, and aircraft condition. The emphasis is on safety rather than speed. On the other hand, 'Land as Soon as Practicable' (LASP) means that the pilot should land at the first suitable landing site without unnecessary delay, but some additional factors can be taken into consideration such as fuel availability or passenger comfort. However, extended flight is not recommended.
The decision to land rests with the pilot in command, who assesses the situation and determines the safest course of action. This allows for flexibility based on specific circumstances.
