Mechanical - Answer: backup to electronic decelerometer as they require longer runway down time and don't provide automatic friction average Dynamic Hydroplaning - Answer: Occurs from water build up Occurs from high speeds Vicious Hydroplaning - Answer: Occurs from the lubricating of oil, rubber, dirt particles combine with water Occurs from Low speeds Rubber reversion - Answer: Less commonly known it is caused by the rubber heat buildup beneath a tire footprint area due to friction. Pavement grooving - Answer: One option to minimize hydroplaning and loss of friction. It consists of forming or cutting closely spaced transverse grooves on the runway surface Porous friction course - Answer: One option to minimize hydroplaning and loss of friction. It consists of a layer of asphalt aggregate with voids in it to allow for better water drainage.
Joint seal damage (Rigid) - Answer: any condition that enables incompressible foreign material such as soil rocks Disintegration (Rigid) - Answer: breaking up of pavement into small loose pieces improper mix of concrete can cause this distress Types of rigid disintegration - Answer: Scaling Alkali Reactivity Joint spalling Corner spalling Flexible pavement distresses include - Answer: Cracking Distortion Loss of skid resistance Cracking (flexible) - Answer: Cracks in flexible pavements are caused by deflection of the surface over an unstable foundation Distortion (flexible) - Answer: Caused by foundation settlement, lack of stability between surface and underlying of the pavement structure
Joint seal damage (flexible) - Answer: Any condition that enables incompressible form material such as soil or rocks to accumulate in the joints that allows infestation of water Records for fueling agent training must be kept how long - Answer: 12 consecutive months Can non movement areas be controlled by by a company ramp tower - Answer: Yes (FedEx ramp at Memphis Airport) Instructions received from the control tower for movements do not imply control responsibility for those areas, who is responsible for these controls and the safe operation of aircrafts or vehicles - Answer: Aircraft and vehicle operators AC 150370-15 - Answer: airside applications on the airfield for artificial turf provide, can mitigate erosion problems made by jet blasts etc main reason for use at airport are to net low cost Artificial turf - Answer: enhances visual aesthetics minimize maintenance and management mitigate erosion
Runway Object Free Area (ROFA) - Answer: An area on the ground centered on a runway provided to enhance the safety of aircraft operations by having the area free of objects, except for objects that need to be located in the OFA for air navigation or aircraft ground maneuvering purposes. Runway Protection Zone (RPZ) - Answer: A clear area beyond a runway end that "not only preclude obstructions potentially hazardous to aircraft, but also to control building construction as a protection from nuisance and hazard to people on the ground Clearway - Answer: A defined rectangular behind the end of the runway clear for use in lieu to satisfy takeoff requirements Taxiway and Taxilane Object Free Area (OFA) - Answer: An area centered on the taxiway and taxilane centerlines. The taxiway and taxilane OFA clearing standards prohibit service vehicle roads, parked airplanes, and above ground objects, except for objects that need to be located in the OFA for air navigation or aircraft ground maneuvering purposes. Visual Approach - Answer: Initiated by either ATC or the Pilot. Requires at least 1000' ceiling and 3SM visibility (IFR under VMC). Pilot must have either the airport or the traffic to follow in sight.
Non-Precision Approach - Answer: Standard instrument approach procedure in which no electronic glide slope is provided Precision Approach - Answer: A standard instrument approach procedure in which both vertical and horizontal guidance is provided. Runway aiming point marking - Answer: Provides a visual aiming point for landing operations. This marking is white and begins 1,020 feet from runway threshold 2 rectangular markings 150 feet in length for runway at least 4,200 feet and 100 feet for runways less than 4,000 feet Continuous Taxiway edge markings - Answer: used to delineate the taxiway edge from the shoulder or some other area not intended for use by pilots Dashed taxiway edge marking - Answer: used where there is an operational need to define the edges of a taxiway route to a sizeable paved area that permits pilots to cross over this surface marking dual dashed yellow lines Taxiway centerlines are enhance for how long past the holding position - Answer: 150 feet
tungsten-halogen bulb - Answer: Incandescent light bulb containing a tungsten filament and a halogen gas. hotter filament, longer lasting flourescent - Answer: Generate light through low pressure gas discharge used for internal lighting of airfield signs Stopway Edge Lights - Answer: unidirectional red lights oriented toward the takeoff direction of the runway two parallel rows that are equidistant from the runway centerline and coincident with the rows of runway Runway centerline lights - Answer: required for CAT II and CAT III runways and for CAT I runways used for landing operations below 2,400 feet RVR. Runway centerline lights are required on runways used for takeoff operations below 1, feet RVR. Although not operationally required, runway centerline lights are recommended for CAT I runways greater than 170 feet in width or when used by aircraft with approach speeds over 140 knots Rotating Beacon - Answer: 24-30 rotations
