As haul flight (Engl. Cross Country or short XC ), the motorless flying a glider , a hang glider or paraglider understood, in which attempts greatest possible route to traverse or cope with a predetermined distance in the shortest possible time. Thermal flights within the own glide angle range do not count as cross-country flights. To document the flight, photos of prominent points on the flight route and turning points as well as a barogram for altitude recording were created. GPS loggers are now used for this purpose .

technology

Since this sport is only practiced with aircraft that do not have their own propulsion devices, attempts are made to gain altitude by using thermals or other updrafts , which is then used for the onward flight to the next updraft.

Gliding

In addition to altitude and speed records, long distances are conquered in gliding in the international competition in the FAI class D " Gliders & Motorgliders ". Distances of up to 1,000 km are no longer uncommon. These are increasingly flown with the help of lee waves , large-scale air oscillations in the lee of mountain ranges. With classic thermal flying , the time window between the beginning and the end of the thermal would no longer be sufficient.

Paraglider / hang glider

competition

A special form of cross-country flying is competition in direct comparison with other pilots. The aim is to cover a distance determined by turning points in the shortest possible time. These competitions are held in different national and international classes; z. B. in the Paragliding World Cup (PWC).

A special event is the Red Bull X-Alps , in which the pilots only race across or over the Alps on foot or by paraglider.

Cross country competitions

Cross-country flying competitions are usually held locally. I.e. each pilot determines his own starting point and time. He then tries to fly as far as possible. Documentation is carried out using GPS. The track recorded by the GPS device is then downloaded to a server for analysis. With the help of an evaluation formula, the flight is evaluated and given a score according to the rules.

Cross country flying as a recreational sport

In addition to cross-country flying in competition, many smaller and larger routes are also carried out by less competitive pilots. Due to the simple documentation, many of these flights can also be found on the usual online servers (see online contest ).
