We did have to haul ourselves along the Inca Trail, a high-altitude path with a number of steep ascents and descents.
I Inca Trail (Peru) Splendid as the sites and views may be along the demanding, high-altitude path built by the Incas, it's arriving at the breath-taking, ancient city of Machu Picchu that is the icing on the cake.
Flying with pre-determined guidelines, including altitude, flight path and airspeed, the ALS pulses the terrain with more than 16 laser beams per square metre during flights.
I had not counted on the extra mileage, nor had I thought about the effect that hiking at altitude (the path goes up from about 5,000 feet, and ends at an elevation of over 6,000) would have on my sea-level system.
Despite this, ERAM represents a quantum leap in flight management technologies, tracking aircraft identity, altitude, flight path, and speed, doubling the number of flights tracked by controllers.
This flight-path angle profile is designed with required altitude, flight-path angle and range-to-go, and then optimized as a one-parameter search problem to meet the velocity constraint.
This technology has the advantage in that it is helicopter mounted, allowing for relatively slow air speeds and low altitude flight paths which result in the collection of extremely high resolution height data (10 cm).
If it weren't for the way the chairs are arranged in groups, or the fact that the ministering staff wear a variety of unflattering uniforms, I thought, this might be the business-class section of some wide-bodied jet bumbling down to Heathrow along a dangerously low-altitude flight path.
First, antiaircraft defenses had improved to a point where bombers could no longer reach their targets with the usual high-altitude flight paths.
"His breath indicated an arduous journey, some steep path, altitude.
Its flight computer would then manage the best speed, altitude and flight path to ensure that the plane landed on time.
