48.4. Modern passenger airliners fly at altitudes ∼10 km. The supersonic airliners “Concord” and “TU-144” that were used for sometime, flied at the altitude 15–20 km, although now they are out of service. The projected supersonic aircrafts of the future, apparently, are going to ...
Overall, drivers of flight altitudes that were related to thermal updrafts showed different levels of complexity due to spatial and temporal variation of those drivers than did flight altitudes related to orographic updrafts.Duerr, Adam EMiller, Tricia A...
it does not provide the aircraft's actual height above ground. At low altitudes the true height of an aircraft relative to an object on the ground needs to be known. The pressure setting to achieve this is calledQNHor "altimeter setting" and is available from various sources, including...
The Northerly Turning Error occurs during shallow turns through southerly and northerly headings. As a rule, the compass “leads” when turning from southerly headings, and “lags” when turning from northerly headings. There is approximately no turning error when turning east and west headings....
Ocean tracks often start and finish perhaps a hundred miles offshore at named waypoints to which a number of airways connect. Tracks across northern oceans are suitable for east-west or west-east flights, which constitute the bulk of the traffic in these areas....
A characteristic of RF signals in the S-band range is that "line-of-sight" must exist between transmitting and receiving antennas to permit communications. With the availability of the east and west TDRS, potential total S-band PM support time using direct and relay links will be as much as...

GA flight and the minimum legal altitudes for this is 500 ft over non populated areas or 1000 ft over populations and these are AGL altitudes. So one can legally fly along a coastline at 500 ft AGL IF this coast is not along a populated area and the airspace is not otherwise restricted...
I mentioned my plans to do this in the Oz Rally FBO a while back, but now I've started the flight itself. and its backstory takes some telling. My youngest daughter is a Warrant Officer in the RAF and she's based at RAF Shawbury in the West Midlands of t
