Just curious, do you have info that supports this? Not challenging the statement, just interested. I would have thought that intersection takeoffs were simply not done unless runway construction etc mandates such a departure.
"PJ2"
Not sure about other countries or foreign carriers operating in Aus etc (my experience doesn't stretch that far), but from the Australian documents:
"A pilot wishing to use less than the full length of the runway available should nominate the intention when requesting the taxi clearance" AIP ENR 1.1-4.3.11
"ATC may offer an intersection departure and will advise the remaining runway length of the runway if required" AIP ENR 1.1-4.3.12
And one must not forget
"The pilot in command must ensure that the runway is suitable for the operation. If not suitable for an operational reason, ATC must be advised before taxiing or when requesting an airways clearance by using the phrase: "REQUIRE RUNWAY (number)" ............. The decision to take off rests solely with the pilot in command" AIP ENR 1.1-4.6
