Practice
The Spencer aerobatic box is available for practice in advance of the contest under the waiver and special provisions listed below.
The current plan calls for the box markers to be set up on Wednesday, August 8. Practice flights will be available provided there is an authorized Chapter 78 person to open the box and personnel available to act as a ground observer and monitor local CTAF and box frequencies.
To use the box during these times you must first:
1. Read and understand the FAA waiver
2. Sign the printed waiver at Spencer.
3. Coordinate each of your flights with the person running box operations.
