PPl 4 qustion need answer AIRCRAFT GENERAL KNOWLEDGE
 

Hello every body

can you answe these qustion plz

A

B

C

D In series mode.


The services connected to a supply bus-bar are normally in:

A

parallel, so that isolation of loads decreases the bus-bar voltage.

B

series, so that isolation of loads increases the bus-bar voltage.

C

parallel, so that isolating individual loads decreases the bus-bar current consumption.

D series, so that isolating one load increases the bus-bar current consumption.

The pitch angle of a constant-speed propeller

A

increases with increasing true air speed.

B

only varies with engine RPM.

C

decreases with increasing true air speed.

D is independent of the true air speed.

The diffuser in a centrifugal compressor is a device in which the:

A

pressure rises and velocity falls.

B

pressure rises at a constant velocity.

C

velocity, pressure and temperature rise.

D velocity rises and pressure falls.



i need the answer plz it is very importent

Best Regards

I can understand that you need the answers, maybe even urgently, but you really need to learn these subjects and not just learn the answers by wrote. This stuff is also pretty basic so it appears you must have been asleep during the first lessons so unless you catch up by revision, you'll be left by the wayside. Believe me, you will need this information.

PM

Thank You Bro For Your Answer And I Will Study This Very Good But Any Way What The Answr For These

Best Regards

I go be good pilot, I expert, I no need you advice, I no need anyone advice. Just give me answer so I pass test, then I go fly for India airlines.

Sir, if you do in fact think you will study, then go ahead and study. Do not believe that you can obtain your answers from a web forum, nor should you put your faith in having answers to these extremely simple questions giving you the ability to fly an airplane, let alone one with the types of systems described by these questions.

Why not just help the guy?

Question 1:D

Question2: D

Question3: B

Question4: C

Hope this helps.

You would help him more if you explained the thinking behind your answers!, then let him decide if you are correct.

1. look it up in wikipedia

2. surely they are coinnected in parallel, as you shed a load the bus current goes down

3. job of constant speed prop is to maintain constant rpm - so A is closer answer

4. pressure rises and velocity falls .... wikipedia is your friend

:E.........

tut, tut := !!!!

Thank you all for your help

the problem is that the ground school in swedish language this is the reason that i asked about these qustion in english to translate it

thank you

best regards

I don't know how bad your swedish is, but your english ain't that good. Maybe you should be taking the ground school in a language you can understand.

I must be stupid, but
 

With 13000 hrs ATP, with FAA, JAA, GCAA and DGCA, I can not answer these questions.

pray to God I dont have to resit my PPL exam.

I am a retired professional pilot and CAA consultant lecturer from PPL level to ATPL.

May I suggest that you consult a professional tutor to answer your questions and not rely upon response postings on this site!

I am able to answer ANY questions you may have, but since I am a professional, I require payment in advance.
