DGCA MET PAPER-4
1. A layer in which the temperature decreases with 1°C per 100m is
A. absolutely stable
B. absolutely unstable
C. conditionally unstable
D. neutral for dry air
2. Stratosphere extends from Tropopause to
A. 50 km
B. 60 km
C. 40 km
3. Compare the following TAF and VOLMET reports for Nice: TAF 240716 VRB02KT
CAVOK = 0920Z 13012KT 8000 SCT040CB BKN100 20/18 Q1015 TEMPO TS = What
can be concluded from the differences between the two reports?
A. That the weather at Nice is clearly more volatile than the TAF could have predicted
earlier in the morning
B. That the weather conditions at 0920 were actually predicted in the TAF
C. That the weather in Nice after 0920 is also likely to be as predicted in the TAF
D. That the VOLMET speaker has got his locations mixed up, because there is no way
the latest VOLMET report could be so different from the TAF
4. An outside air temperature of -35°C is measured while cruising at FL 200. What is the
temperature deviation from the ISA at this level?
A. 10°C warmer than ISA.
B. 5°C warmer than ISA.
C. 5°C colder than ISA.
D. 10°C colder than ISA.
5. The reason for the fact, that the Icelandic low is normally deeper in winter than in summer
is that
A. the temperature contrasts between arctic and equatorial areas are much greater in
winter.
B. the low-pressure activity of the sea east of Canada is higher in winter.
C. the strong winds of the north Atlantic in winter are favourable for the development of
lows.
D. converging air currents are of greater intensity in winter.
, 6. During a flight over the sea at FL 100 from Marseille (QNH 1012 hPa) to Palma de
Mallorca (QNH 1012 hPa), the true altitude is constantly increasing. What action, if any,
should be taken ?
A. Compensate by heading further to the left
B. None, the reason for the change is that the air around Palma is warmer than the air
around Marseille
C. Have your altimeter checked, because its readings are obviously wrong
D. Recheck the QNH because one of the QNH values must be wrong
7. 850 hPa in ISA corresponds to the level
A. 7,000ft
B. 5,000 ft
C. 10,000 ft
8. The pressure altitude is equal to the true altitude if
A. the outside air temperature is standard for that height
B. the air pressure is 1013.25 hPa at the surface
C. the indicated altitude is equal to the pressure altitude
D. standard atmospheric conditions occur
9. An aircraft lands at an airport (airport elevation 540 FT, QNH 993 hPa) with the altimeter
set to 1013 hPa. What will it indicate ?
A. 380 FT
B. 0 FT
C. 1080 FT
D. 700 FT
10. The morning following a clear, calm night when the temperature has dropped to the
dewpoint, is likely to produce
A. a cold front
B. advection fog
C. good clear weather
D. radiation fog
11. Minimum temperature is reached at ...
A. sunrise
B. midnight
C. 1/2 - 1 hour after dawn
12. A wide body takes off on a clear night in Dhahran, Saudi Arabia. Shortly after take off the
aircraft's rate of climb drops to zero. This can be due to
A. very pronounced downdraft
B. low relative humidity
C. a very strong temperature inversion
D. sand/dust in the engines
