McLaren's proposed Pirelli test in Austin has been cancelled much to the disappointment of team boss Martin Whitmarsh.
McLaren had hoped to help Pirelli test their 2014 tyres during a test in a 2011 car ahead of the United States Grand Prix.
However, as rivals complained that McLaren would get an unfair advantage, the FIA ruled that the run could not take place.
"I think testing the 2011 car with 2014 tyres, and with all due respect to them, Oliver Turvey or Kevin Magnussen doing the driving, it was not going to be an awful lot of help for us," Whitmarsh told Autosport.
"It is not an over-riding disappointment, but what is I suppose disappointing if that Pirelli clearly want to do the test.
"They have a challenge on with the rear tyres [for 2014] and we are denying them that opportunity. So that is not good really."
The team boss, though, says he has no plans to try persuade McLaren's rivals to give them the go-ahead.
"I said all along that we would completely respect what the other teams thought, and you can see it from the FIA's point of view.
"People have been asking if we should try to go and appeal and argue: but it is more about how it would be viewed. It doesn't matter it is the 2011 car, or 2014 tyres - you can see people will build it up into 'McLaren getting an advantage'. So it is about perception.
"I can understand the FIA's position on it and I suspect a couple of teams chipped in and said this was scandalous, but ultimately it is the FIA's decision.
"I am not surprised, but I don't think it is particularly rational. But we are driven by emotions aren't we?"
