20,000
What are the limitations for a tripped circuit breaker
Only reset once

TCAS Limitations
Flight crews must immediately respond to TCAS information (both TA and RA) by using TCAS (Traffic Avoidance) guidelines located in the QRH Maneuvers Chapters

Alternate Flaps Limitation
Alternate flaps duty cycle in flight is one complete cycle then 5 minutes off.
A complete cycle is movement from 0 to 15 and back to 0.

~ Center tank fuel pumps must NOT be positioned ON unless the center tank fuel qty exceeds 1000 lbs, except when de-fueling or transferring fuel
~ Center tank fuel pumps must NOT be positioned ON unless personnel are available on the flight deck to monitor LOW PRESSURE lights
~ Flight crews MUST NOT reset tripped fuel quantity, fuel pump, fuel pump control circuit breakers.
Limitations of Circle To Land
Both 1000 ft ceiling AND 3 SM vis
Review Jepp for specific wx mins greater than 1000/3. Higher mins are controlling
Use a MDA of 1000 ft above field elevation unless restricted to higher altitude in circle approach section of Jepp.
