ALTITUDE. Operators follow voluntarily agreed upon routes for tour flights and maintain minimum altitudes of 1,500 feet for helicopters operating above residential areas, except during takeoff, landing or when deviations are required by weather or traffic.
ALTITUDE. It is good airmanship, and also the law, to maintain a safe altitude at all times and to ensure that when flying over residential areas this is maintained. Except when in the act of landing or taking off the minimum height fixed wing aircraft will fly at is 1,000 feet over inhabited areas and 500 feet over uninhabited areas or the sea. Night circuits must not be conducted at a height less than 1,000 feet. CASA may approve aircraft operations to routinely operate at lower altitudes, such as emergency service aircraft (e.g. Police, bushfire water bombers, search and rescue operations) and special types of air work for which the operator has a permit (e.g. media helicopters, aerial surveying and environmental spraying). There may also be times where aircraft need to fly at lower heights due to the weather (e.g. low cloud).
ALTITUDE a. All data block altitudes will reflect the aircrafts assigned “hard” altitude.
b. Temporary altitudes may be used, but should be cleared prior to handoff unless otherwise coordinated.
c. Both facilities shall ensure aircraft comply with altitude assignments noted in Attachment C

ALTITUDE. The Seeker shall operate within the requirements of this specification over an altitude range of -1500 m (-5000 ft) to +3000 m (10,000 ft) MSL. Note: The high negative altitude requirement reflects operation in deep mine shafts.
ALTITUDE. The transceiver shall operate at altitudes up to 10,000 feet. Conditions associated with the altitude exposure are as defined in MIL-STD-810E, Method 500.3, Procedure II.
ALTITUDE. A. arabiensis is one of the principal vectors of malaria in throughout sub-Saharan Africa often oc- curring sympatrically with A gambiae s.s,. However, in some areas, such as the Great Rift Valley in East Africa, A. arabiensis is the predominant malaria vector species (Minakawa et al. 2002). Xxx- xxx et al 2003 also found A. arabiensis to be the principal vector responsible for malaria transmis- sion in Ethiopia and Eritrea, also known as the horn of Africa. These countries have similar high- land topographies and high elevation characterized by unique mountainous areas, rugged plateaus and interspersed with towering mountains and deep chasms. Hot and humid low lands and semi- desert areas. With average elevation of 2000 m above sea level and scarce rainfall, this confirms that A. arabiensis is better adapted to dry environments than A. gambiae (Xxxxxxx et al. 1998). Observations of Imbahale et al (2011) from Fort Ternan in western Kenyan highlands, indicate that
A. arabiensis comprised 71% of A. gambiae s.l. collected. This is the highest proportion of this species that has ever been recorded in the highlands of western Kenya. Fort Ternan has average weekly air temperature of >19°C and an average maximum relative humidity of >80% providing conducive conditions for malaria transmission. However, the valleys in Fort Ternan are narrow with steep slopes, causing a rapid drainage of water unless human activities create or construct water-retaining structures. The presence of A. arabiensis in Fort Ternan can be attributed to the slow changes in land use, such as deforestation, that leads to changes in micro-climatic conditions favouring the survival of this species. The air temperatures found were lower than the correspond- ing water temperatures in the sampled habitats, a factor that seems to favour the existence of A. arabiensis in high altitude areas.
ALTITUDE. Altitude is set in metres and can be searched against as you would for any numeric field. The operators available are: =, !=, <, <=, >, >=.
