The paper gives problems and methods of introducing contemporary maintenance strategies on the basis of worldwide experiences. The analysis of maintenance in our as well as in other military systems resulted in suggesting possible strategies, conditions of their application and possible combinations. The method of their implementation and application is analyzed as well as possible effects. Adequate recommendations are also given.

Reliability of aircraft and their systems and equipment is one of the most important problems which must be considered and analysed. This analysis is based on the number and periods of failures for the last few years and it describes the determination of the parameters of aircraft avionics reliability using certain graphic methods.

Automatic and adaptive radio communication systems are developed to ensure better quality and easy link establishment and transmitting of messages over the HF radio channel. Automatic link establishment is a robust, adaptive HF radio method for automatic communications establishing over the HF SSB link. The overview of this technology, the principles of automatic link establishment and the analysis of conventional and adaptive radio systems are the contents of this paper.

The possibility of a vehicle to accelerate is very important for special-purpose high-speed tracked vehicles, especially for combat vehicles. It determines vehicle dynamic characteristics and has an important role for vehicle survivability. The determination of basic vehicle acceleration parameters is mostly carried out experimentally on realized vehicles but for vehicles in development it is determined by calculation. Some problems are present during the calculation because it is not possible to take into account all influencing parameters. The procedure for an easy calculation of these parameters is given in this paper. The values of the parameters obtained by this procedure are close to real values.

Savremeni vazduhoplovi predstavljaju složene sisteme koje treba efikasno i u određenom roku ispitati sa osnovnim ciljem da se utvrdi kvalitet leta u opsegu proračunom datih ograničenja, performansi leta unutar projektovane anvelope i stabilnost i upravljivost u toku izvođenja zahtevanih manevara. Ispitivanja u letu mogu biti usmerena i ka istraživanju drugih fenomena koji se ne mogu ustanoviti na drugi način. Ispitivanje u letu je od presudne važnosti, a s obzirom na to da je to poslednja faza stvaranja letelice, jer se samo u realnim uslovima upotrebe mogu potvrditi svi inicijalni zahtevi projektovanja i verifikovati njene performanse uz maksimalno vođenje računa o bezbednosti ispitivanja. Ispitivanje u letu sprovodi se po tačno definisanom programu koji mora zadovoljiti veliki broj civilnih i vojnih vazduhoplovnih propisa. Specifičnost ove faze stvaranja letelice je u tome što obezbeđuje povratnu informaciju timu konstruktora o opravdanosti njihove procene ili daje prostor za alternativu u projektu. Pored toga, konstruktori stiču uvid u saglasnost projekta sa zadatim specifikacijama i ponašanju letelice u stvarnim uslovima aplikacije. Vazduhoplovni opitni centar u Batajnici spada u red savremenih opitnih centara. Pored vojnih aplikacija raspolaže i svim civilnim ovlašćenjima koja mu omogućuju tržišni nastup u zemlji i inostranstvu.
