Honored test-pilot, test-cosmonaut and engineer. He graduated from Kirovograd Higher Military Pilot School and "Zhukovski" branch of the Moscow Aviation Institute, his major being technical engineering, and also finished the test-pilot training program of the Flight Research Institute with the Ministry of Aircraft Industry. He has flied all types of Soviet aircrafts, including fighter aircrafts, military cargo aircrafts and bombardment aircrafts. He has completed the working cycle on different automated flight management systems, as well as fine-tuned test and modified propulsion power systems. He has carried out aircraft tests, including spinning dives and high angles of attack, inertia coupling, resistance and hardness, aerodynamics and flight dynamics. He has conducted researches on replenishment of fighter aircrafts and in-flight refueling. He has also conducted a series of important and complex tests and experiments, including spin-diving of Su-27 ans Su-27UB aircrafts. His total flight hours exceed 7000 hours, whereas his test-flight duration is over 3500 hours.
He has also taken part in endoatmospheric tests of an aerospace vehicle, developed under the "Spiral" project. At the end of 1978 he was given the post of a test-pilot No. 1 commander of complex "A" of the Flight-test Center. He has undergone general cosmonaut training in the Cosmonaut Training Center "Yurii A. Gagarin". He was a member of the test-cosmonaut command with the Flight Research Institute of the Ministry of Aircraft Industry, having been acknowledged the qualification of a "test-cosmonaut".
Within the period of 17-29 July, 1984, he took part in the expeditions on visiting spacecrafts "Soyuz T-12" and OS "Salyut-7", in his capacity of test-cosmonaut. Within the framework of those tests, immediately upon landing, he piloted helicopters and aircrafts Tu-154 and MiG-25 along the route Baikonur - Ahtubinsk - Baikonur aiming at evaluating the ability of a cosmonaut to pilot space shuttle "Buran" following performing works in orbit. Since 1984, under the program for preparation of the space transportation system (STS) "Buran", he carried out works and test on the manual management system and the automated landing systems on the flying test-bench Tu-154, fitted with "Buran" management system, and worked on flying test-bench Su-7 and MiG-25, which are much similar, in terms of aerodynamics, to STS "Buran". I. P. Volk, within the framework of "Buran" project, has carried out five aircraft taxiing and thirteen flight operations on the special aircraft BTS-02. He had to be the aircraft crew commander on the first flight of STS "Buran".
A First Class Test-Pilot. A Third Class Cosmonaut.
He also held the post of a Head of the sectoral complex for test-cosmonauts training with the Flight Research Institute, head of the Pilot Training Center with FRI "Gromov" and deputy head of FRI "Gromov". He was the first Vice-President of the Russian Cosmonautics Federation (RCF), Chairperson of the Executive Committee of RCF.
