1 a Sufficient moisture in the air and lifting action are also other ingredients.
2 c Windspeed of up to +/-100kt in microbursts have been recorded in America and elsewhere but are unlikely to exceed 45kt over Europe. But if a light aircraft flying at say 110kt IAS were to encounter such a microburst it could initially accelerate to 155kt then decelerate to 65kt within less than a mile. Best avoided
3 b But also only if you are flying upwind of the storm cloud because anvils form on the downwind side of a thunderstorm cloud, the trajectory of hailstones falling from them can be much larger, sometimes as far away from the Cu-nim as 1nm per knot of windspeed at the anvil height.
4 d Turbulence poses the greatest threat to aircraft safety in thundery conditions, and generates the static electricity which causes lightning, so pilots should avoid flying anywhere near lightning. Frequent lightning flashes usually mark the developing stage of a thunderstorm but it is potentially dangerous for aircraft to fly through any towering cumulus cloud (TCu or Cb) even if no lightning can be seen
5 d original title of what became Panavia Tornado
7 e None of these. A diagonal cross inside a circle indicates a disused or abandoned aerodrome and these symbols appears on charts solely to indicate navigational landmarks
8 d Watt (W)
