C.10.2 Performance Information
The GSU 73 is capable of maneuvers through a range of 360° in bank and pitch. The rotation rate
capability is ±200° per second.
Bank error and pitch error are within 1.25° over the range of 30° bank, left and right, and 15° pitch nose
up and nose down. Heading is accurate to within 2° in straight and level flight.
Due to unsuitability of the magnetic fields near the Earth's poles, operational accuracy is unknown in the
following regions:
1. North of 72° North latitude at all longitudes
2. South of 70° South latitude at all longitudes
3. North of 65° North latitude between longitude 75° W and 120° W (Northern Canada)
4. North of 70° North latitude between longitude 70° W and 128° W (Northern Canada)
5. North of 70° North latitude between longitude 85° E and 114° E (Northern Russia)
6. South of 55° South latitude between longitude 120° E and 165° E (Region South of Australia and
New Zealand)
