A great shame
Pilots without physics wouldn't be able to see the necessity of physics - a situation akin to "you don't know what you don't know".
Hands up all those that subscribe to the idea that, upon reaching top of climb, rather than just level out and allow the aircraft to accelerate, you climb a few hundred feet more, accelerate, then descend down to the cruising altitude so as to leave you with a higher cruising speed?
There are many, many pilots in Australia that subscribe to this idea. I have heard this "technique" referred to as "getting over the step". I have even heard pilots requesting a "climb overshoot" to ATC when about to conduct it.
If these pilots had done physics (and understood it) they wouldn't be doing that because they would know that there cannot be any benefits to it - and, they would also know that, in fact, doing so only prolongs the time it takes to get settled down in the cruise!
A pilot with an understanding of physics is a much more astute pilot than one without.
A great shame, but such are the commercial realities facing Qantas.
