Not computing the perfs inflight has never caused a single accident/incident (if it has, please point it out).
Computing the perfs inflight is not even a legal requirement.
That makes two very clear points against your opinion.
Then there is the post just above who does exactly what I advocate : assessment does not necessarily need a calculation.
Which is a third very strong point.
However what did cause accidents related to perfs calculations is two things :
- Inability to understand that calculations have assumptions that must be met, or inability to meet them
- Inability to detect gross errors about takeoff calculations
To finish with, don't bother too much about my career. I know what opinions not to say in a training context. And know when and how to debate them to promote my point of view.
I'm just out of a type rating : my trainers valued my way of thinking and promoted it with a better mark in the "knowledge" competency.
Under EASA regulations You are at least required to compute Dispatch Landing requirements as I quoted a few posts above directly from the regulations. If your operator specifies otherwise then happy days. I wonder how you ensure that you comply with GA gradients without running in-flight landing performances (yes we could lose an engine during a normal Go Around -birds?).
I wonder how you can land with idle reverse (noise sensitive place, hello?) on a wet runway without running the in-flight landing perf. By using RCC 2 and select the appropriate auto brake that complies.
I wonder how you can demonstrate that you can use auto brake low on a short runway with RCC 6 or 5 because the LD is below the FLD and you have no brake fans (medium will kill your short turn around with those lovely summer temps…)
Anyway enjoy it as you like it, I am no one to tell you to do otherwise. 😄
