an aircraft has to communicate with a VHF station at a range of 300 nm,if ground station is situated 2500 ft amsl,which is the lowest altitude at which contact is likely to be made???

Question Bank
 

I shall be highly grateful if someone can send me the question bank. my email id is [email protected]



Regards

range= 1.25 under root(h1) + 1.25under root (h2)
h1=2500
h2=FL36
rANGE=300

has anyone rcvd the call letter with a roll number,date and location yet?

but the answer is 33,600 ft

Sometimes its the most suitable answers what examiners are looking for.......if there are choices you should have mentioned in the question

THIS QUESTIPON HAS BEEN PREV ASKED IN THE FORUM

An aircraft has to communicate with a VHF station at a range of 300 nm, if the ground station
is situated 2500' amsl which ofthe following is the lowest altitude at which contact is likely to
be made?
a) 190'
b) 1,378'
c) 37,600'
d) 84,100'

Range (nm) = 1.25 sq root ht. of transmitter + 1.25 sq. root ht of reciever
300 =1.25 sq root 2500 + 1.25 sq root ht of rec.
300 = 62.5 + 1.25 sq root ht of rec
300-62.5 = 1.25 sq root ht of rec
237.5 =1.25 sq root ht of rec
237.5/1.25= sq. root ht of rec ( Assume this to be X feet amsl )
190 = sq root x
sq. both sides
x= 36100 feet
Hence, the close option is C

can someone please tell me whr is the exam conducted ?

venue adn hall ticket ?
 

has Capt. Upendranath sent the hall tickets adn dates to anyone for the june 20th attempt ?

june 20 - june 23 ..!

doubt
 

can anyone please post the solution to this question.thnx in advance.

1) A great circle track joins position A (59?S 141?W) and B (61?S 148?W). What is the difference between the great circle track at A and B?Ans. It increases by 6°

convergency = change of long * sin latitude (mean)

conv = 7 * sin60which gives 6.02

Convergency gives the heading change when gc is followed
and HEADING increases to fly gc track westwards in SH

@ ilsdme28
Thanx a lot for your reply. But I am confused with the part that it increases,shouldnot it decrease? Can u please explain this.

@Aviator4u
 

It's increasing cuz it's SHS..Reading decrease in NHS & increase in SHS..

You need to draw it correctly to see why it increases .......i will advise you to look at gsp navigation .....
