Missed Approach Performance
An interesting reminder about missed approach performance; specifically note:-
"Balked landings, initiated after touchdown but before reverse thrust application, present unique challenges due to limited regulatory guidance and the need for engineered assumptions in performance evaluation. The analysis methodology parallels that of missed approaches but requires careful modeling of conservativisms, configuration transitions, and thrust management. Flight path analyses at challenging airports, including those with high elevation, high temperatures, or “hot and high” conditions, reveal performance limitations that can make achieving a positive rate of climb under OEI conditions difficult. This situation highlights the need for mitigation strategies such as operational weight restrictions, deviation from standard procedure (EO routing not aircraft operating?), and enhanced crew training."

Where this is a consideration, your Fleet Technical Team and Performance Engineers should have prepared specific rejected landing instructions. They are often identical to the Engine Failure procedure for departing the same runway. It is worth noting that PANS OPS requires far better obstacle clearance for a missed approach than Perf A requires for takeoff.
Not all operators do a comprehensive analysis though!

A very well written paper.
Even I, a helicopter driver whose fixed wing experience was mostly “bush” ( I think I can land on that lake surrounded by hills and trees and take off again in my single engine 1 ton pickup truck) could understand it.
The elephant hiding at the back of the room in these days of crowded airspace and airports.
The horrible scenario of a runway incursion perceived after the touchdown and deployment of reverse thrust must be something that many have thought of. You can’t go around so all you can do is apply max reverse and braking while steering to avoid colliding with the other aircraft even if it means leaving the runway. Even such a scenario before reverse thrust selection is a conundrum as if you do elect to attempt a baulked landing go-around you may collide with the other aircraft at high speed, high power and a high pitch attitude.
