I guess even if it does begin to load shed at 50kts, Envoy dgaf if anyone knows it. Anyways. Cool.

"SPDA1 or SPDA2 generates CAS advisory message LOAD SHED if one of the following conditions
exist:
• AC Generator capability is reduced to only one source (only one IDG or APU generator) while in
the air mode.
• One AC Generator is sensed as supplying greater than the full load rating, regardless of air/
ground mode and AC Generator capability.
(3) An IDG or APU GEN overload is defined as follows:
• Phase A, B, or C current is between 116 and 130 A for 2.5 min.
• Phase A, B, or C current is between 130 and 174 A for 2.5 s.
(4) CAS advisory message LOAD SHED is reset when the above conditions no longer exist.
(5) CAS advisory message LOAD SHED is inhibited during takeoff, landing, or while in flight"
