Question 246-3 : Contaminated runways..for an aeroplane with a tyre pressure of 16 bars, there is a risk of dynamic hydroplaning as soon as ?
Speed is greater than 138 kt.
.you first need to convert bars to psi..bars x 14.5 = psi..16 x 14.5 = psi..psi = 232....for a rotating tyre, dynamic hydroplaning = 9 sqrt p..for a non rotating tyre, dynamic hydroplaning = 7.7 sqrt p...p is the tyre pressure in psi...unless states in the question, we assume a rotating tyre, so...9 sqrt 232 = 137 kt... sqrt = square root.

2, 4.
. /com en/com070h 9.jpg.. gderoq111.this image doesn't explain increasing tailwind during approach landing....guess what a decreasing headwind is similar to an increasing tailwind...the increase in tailwind will cause a decrease in ias/tas, hence if you do nothing about it, you will go below the glide path.

Question 246-26 : Viscous hydroplaning occurs primarily if the runway is covered with a thin film of water and ?
The runway is very smooth and dirty.
.as a tire rolls along a wet runway, it is constantly squeezing the water from the tread. this squeezing action generates water pressures which can lift portions of the tire off the runway and reduce the amount of friction the tire can develop. this action is called hydroplaning, so technically, whenever a tire is moving on a wet surface, it is hydroplaning. this results in tire to ground friction which can be low at high speeds and improve as speed reduces...there are three types of hydroplaning viscous, dynamic and reverted rubber... viscous hydroplaning.viscous hydroplaning occurs on all wet runways and is a technical term used to describe the normal slipperiness or lubricating action of the the water..a thin film of water acts like a lubricant. the microtexture of the runway surface sandpaper like roughness breaks up the water film and greatly improves traction. viscous hydroplaning is the most commonly encountered cause of low friction on wet runways, and occurrences are often mistaken for dynamic hydroplaning.. 2653.. dynamic hydroplaning.dynamic hydroplaning is the technical term for what is commonly called.hydroplaning. during total dynamic hydroplaning the tire lifts off the pavement and rides on a wedge of water like a water ski.. 2654.. reverted rubber hydroplaning.reverted rubber hydroplaning can occur whenever a locked tire is skidded along a very wet or icy runway for a time long enough to generate frictional heat in the footprint area. reverted rubber hydroplaning can be initiated at any speed above about 20 knots and results in tire friction levels comparable to that of icy runways..reverted rubber hydroplaning. when a tire locks up on a smooth wet or icy surface, the friction heat generates steam. the steam pressure then lifts the tire off the runway and the steam heat reverts the rubber to a black gummy deposit.. 2655

1, 2, 3.
.wake turbulence is formed whilst you are creating lift, it is the flow of air from the high pressure surface of the wing underneath to the low pressure surface top at the wing tip..these vortices then sink slowly downwards and outwards. so, heavy clean slow produces the greatest pressure differential between the two surfaces of the wing.

Question 246-38 : The icao procedure designed to collect and disseminate information on bird strikes to aircraft is called ?
Ibis icao bird strike information system.
.icao began to monitor bird strikes, in 1965, through the collection of bird strike reports which led to the creation of the icao bird strike information system ibis in 1980..since that time, increases in bird strike reporting, which have come about through a greater awareness of the problem and the efforts of those states actively involved in the field of airport wildlife control, have provided a better perspective of the present bird strike situation..the number of bird strikes occurring world wide appears to be increasing. this increase is the result of many factors, including increased numbers of aircraft movements new quieter aircraft and, in many parts of the world, highly successful wildlife bird conservation efforts..while estimates vary, it is now believed that more than 50,000 bird strikes occur to civil aviation aircraft each year. bird strikes are truly a worldwide phenomenon, as demonstrated by the fact that bird strikes have occurred in more than 190 states and territories, from every icao region...ibis data reveals that ninety percent of bird strikes, with known locations, occur on or near airports. birds are attracted to airports and to the airport vicinity for a variety of reasons, all basic and tied directly to their survival. however, their basic needs put birds in direct conflict with the aircraft using airports and, unless an effective airport bird control programme is in place, it is inevitable that collisions between aircraft and birds will occur...while the vast majority of bird strikes have no effect on the flight, approximately eleven per cent of all bird strikes do affect the flight in some tangible way. while rare, fatal accidents resulting from bird strikes have accounted for the loss of 400 lives and the destruction of 420 aircraft.
