Abstract : Requirements for repair quality of a damaged runway are highly dependent upon the design capabilities and the strength of an aircraft and its undercarriage. It is obvious that, regardless of the repair technique, low repair quality will save valuable time to the reopening of a damaged runway for use. Accurate knowledge of the behavior of the aircraft on non-flat surfaces is necessary and it is standard practice to develop a computer model of the aircraft and its undercarriage for analytical coverage of all operational cases. This analytical model requires comprehensive verification in tests. Since development of a service clearance by test along is impossible, due to the vast number of possible initial conditions, it is the verification where the test should concentrate. Tests are also necessary to optimize pilot techniques for the use of the aircraft under such conditions with minimum risk. The paper describes tests, which were performed with a combat aircraft on a runway, where mat repair has been simulated.
