Try these first

1. 1.

   What does GBAS stand for?

   Hint

   Think about the type of corrections it provides.

2. 2.

   Where is GBAS primarily used?

   Hint

   Consider what setting requires precise navigation.

3. 3.

   What is the primary function of GBAS?

   • To provide long-range corrections
   • To enhance GNSS accuracy locally
   • To replace GNSS systems

   Hint

   Consider its application in aviation.

4. 4.

   True or False: GBAS operates solely using satellite-based corrections.

   • True
   • False

   Hint

   Think about where the corrections come from.

5. 5.

   Evaluate the effectiveness of GBAS compared to traditional satellite-only navigation approaches in aviation contexts.

   Hint

   Think about the consequences of positional errors in aviation.

6. 6.

   Design a hypothetical scenario where GBAS could significantly impact the operations of a new airport. What factors would you consider?

   Hint

   Consider both technical and logistical aspects.
