2. Earth is heated by
a) A. Insulation (sic)
b) some bs option
c) another bs option
d) none of the above
Those who know what is Insolation and Insulation, knows that its an ill-made question,
well as far as i know the question was how does the lower tropopause gets heated up and the answer was by long wave radiations from earth
3. If an aircraft descends to a higher altitude at constant IAS
a) M increases
b) M decreases
c) .....
d) .....
Obviously there is a mistake, but which one is mistake, 'descends' or 'higher'
this was the correction which was made in mumbai centre
actually its ASCEND
and so the mach no increases
4. Speed of sound at sea level ISA is
a) 660.7 Knots
b) 661.7 Knots
c) 662.7 Knots
d) 663.7 Knots
What the hell are they trying to evaluate...
buddy i guess this is the given value which you should know always
anyways the answer is 661.7 kts
(39 x root of (273+15)
5. Atmosphere is instable when ELR is
a) > DALR
b) = DALR
c) < DALR
d) none of above (not sure)
In order to determine Instability absolutely one needs to know ELR in relation to SALR, this is not the best way to ask this question.
to know the instability we should always compare with dalr and to know the stability we should always compare with salr
so this question is correct because if the elr lies between salr and dalr then its conditionally unstable
but if its higher then dalr then perfectly unstable
remember this is one of the factor in formation of thunder clouds
6. Aircraft generator are rated as
a) ....
b) KVA
c) KW
d) none of the above
How do KVA and KW differ?
the answer for this is kva
now whats the difference between kva and kw is i kva = 0.8 kw
well some power factor plays a role in their equation
also the question no 2 in first technicqal paper had wrong units
the question was
how much force is required to move a 10 kg object at the rate of 98m/sec^2
and in the options the units were in kgs itself
and they were
10 kg
100 kg
1000 kg
10000 kg
this question was not corrected at mumbai centre
also in one more question in the same technical paper it was said a battery has a capacity of 150 ampere/hour
thats again completely wrong because battery capacity is in ampere-hour and not ampere/hour
