was it a beautiful VFR day close to v1? Expect training procedures in the near future concerning RTO's. Way too many, 9e leads the industry. Stuff like aborts at v1 on contaminated runways for anti skid inop caution or a Gen 1 caution on a clear blue day etc.

Not tryin to bust your balls, since it has been trained that generally we have aborted in the sim for a/s indicator, but expect change like I said so that we aren't so trigger happy to abort. Maybe your non fly thought it was safer to take it into the air rather than abort. What was the wx? you have 2 others. I've had a handful of FO's tell me to abort for a meaningless master warning or master caution. they look at me like a deer in headlights when I continue, until I explain to them why we continued and you see the light bulb go off in their head.

p.s. If I were you I would have not called abort and then the CA would have to shoot the approach for your PC
