Help with a question please
Hi everyone.. i just got a question i have my doubts on " As throttle is increased in a normal aspirated (piston) engine does the manifold pressure increase or decrease???" Also for a supercharged engine does manifold pressure increase or decrease... i have a CAA exam tomorow for piston engines.. it will be of great help if i was able to clear my doubts... thanksss

You should not need to google the answer, anyone with a basic understanding of how a car engine works could work that one out, very worrying so called "engineers" are having to ask questions like that. 
We cover that sort of thing on our basic ground handling techs course.

He's not yet that's why he's doing an exam!
What CAA exams are there for " basic ground handling techs" and is it a recognised qualification? As I've never heard of that, it's not in the ELGD!

The manifold pressure is measured after the butterfly valve, as the throttle opens, so does the butterfly valve - which lets in more pressure. So the pressure increases.
The five posters above are demonstrating their rather distasteful miserly attitude to the human race and can be safely ignored. (In fact there is an ignore list on this forum should you want to use it.)

The 'basic ground handling techs' course is just one of the many modules all security guards must undertake to enable them to not only legally fondle the genetalia of complete same sex strangers, but to be eligible to become a senior licenced security guard capable of performing all manner of maintenance activities on the ramp. Tommy, if you're not sure what the ramp is, its the big area sort of like a big car park where you see all the big airplanes sitting. Oh and the big spinning wheels in the front of the big motors get really really noisy too. In fact I heard it gets so noisy when those big wheels in the front of the big motors are spinning that you cant even hear the valve caps falling off of the wheels or hear the oil leaking from the wheels either.

Guys, I would of thought a straight answer to someone who is probably nervous as hell would have been the way to go instead of detracting him, he came for help not to get slagged off, shame on you and good on you checkboard for helping him out........ we have all at one point been there......... though some i doubt!
It was his first post and was obviously trying to ask it from the horses mouth, unfortunately he seems to have attracted the horses arse in reponse.
Hope it went well Arunboy, I would have answered your query if you still hadn't taken the exam.

A couple of them, yes. But really in this day and age, a simple question as asked by the OP can and should be found by a simple bit of research.
I wish I had been able to access the web when I was studying. Life would have been so much easier.
