1. In the METAR/SPECI above, the dry bulb temperature is:
a) 18 and the wet bulb is 13 and the closer the two temperatures become the higher the probability of fog
b) 18 and the wet bulb is 13 and the closer the two temperatures become the denser the air becomes
c) 13 and the wet bulb is 18 and the closer the two temperatures become the higher the probability of fog
d) 13 and the wet bulb is 18 and the closer the two temperatures become the denser the air becomes
2. Information on the automatic weather stations (AWS) can be received:
a) only by phone (numbers in ERSA)
b) only by ATIS
c) only on certain navaids, VHF/UHF
d) on certain navaids, VHF/UHF frequencies and by telephone
3. A scheduled HF broadcast of forecasts for major airports and a VHF broadcast of METAR are respectively termed:
a) AERIS and VOLMET
b) VOLMET and AERIS
c) AWIS and WATIR
d) WATIR and AWIS
4. For a VFR flight by day to an aerodrome where the forecast visibility of 5000m an alternate is:
a) required
b) not required
c) not required if a private flight
d) not required if the aircraft has a MTOW of 577 kg or less
5. A TTF contains the following information “RMK RF 02.00/004.0” What does this information mean?
a) it is the rainfall recorded in the last 20mins followed by the rainfall recorded since 0900Z, expressed in millimeters(mm)
b) it is the rainfall recorded in the last hour followed by the rainfall recorded since 0900 local time, expressed in millimeters(mm)
c) it is the rainfall recorded in the last 2 hours followed by the rainfall recorded in the past 4 hours, expressed in millimeters(mm)
d) it is the rainfall recorded in the 10mins prior to observation time, followed by the rainfall recorded since 0900 local time, expressed in millimeters(mm)
6. If a TTF was issued for YMML that contained the following “INTER 0204 2000 SHRA BKN 010” then which of the following is a true statement?
a) An alternate or holding fuel of 30 mins must be carried between 0130 and 0430Z
b) An alternate or holding fuel of 60 mins must be carried between 0130 and 0430Z
c) An alternate or holding fuel of 30 mins must be carried between 0130 and 0430Z
d) An alternate or holding fuel of 30 mins must be carried between 02000 and 0400Z

ANSWERS
1. A The wet bulb is lower due to evaporation; the closer they become the higher the humidity; humid air is less dense than dry air at the same temperature and pressure
2. D AWS info from some sites is also avail via telephone
3. B AIP GEN 3.5 -18 VOLMET on HF and AERIS on VHF and broadcasts only METAR
4. A ENR 1.1 para 72.2.13
5. D AIP GEN 3.5 -30 para 12.18.1
6. C AIP ENR 1.1 -87 para 72.2.9
