Inkcazelo emfutshane:

Imiqathango yeNkonzo eqhelekileyo
Umphakamo 1000- 3000m;
Ubushushu bemekobume abukho ngaphezu kwe +40″C, hayi ngaphantsi kwe -30C (ummandla ophakamileyo nobandayo awukho ngaphantsi kwe-40C);
Impepho icinezela hayi ngaphezulu kwe-700Pa;(isantya somoya esilingana ne-34ms/s);
Ubunzulu benyikima abukho ngaphezu kwe-8 degree;
Ubunzima bomkhenkce abukho ngaphezu kwe-10 mm;
Ukufakela indawo akufuneki kuqhume ngokulula iimpahla ezinobungozi, ukubola kwekhemistri kunye nokungcangcazela okunobundlobongela;
Isihlukanisi sentsika ibakala elimdaka kunyana: Uhlobo oluqhelekileyo yiklasi ye-0, khusela uhlobo olumdaka njengodidi lwe-II.
