Engine BMW D-2/328909 to 27.9 .
Engine BMW D-2/316248
A-8 production condition (without outer wing weapons).
Armament: 2 MG 131, 2 MG 151 (MG 151 with ammunition)
ETC 501. Rigid wheel door panels.
Wing nose camera BSK 16 installed (temporarily)
AT-bomb rack mockup with 6 bombs per wing ( Panzerblitz ) 29.9 . / . 6.10.


1.Determine the airspeed indicator error on the test course.
2.Horizontal speeds with combat and take-off power in the as-delivered condition.
3.Speed and flight characteristics control with Panzerblitz.
4.Shooting an instructional film with the BSK 16 gun camera.


1.The ram calibration as flown over the test course was plotted taking into account compressibility and was used to convert the indicated level speeds
2.The graph shows speed performance with n=2400 RPM and n=2700 RPM obtained before the implementation of the planned fuselage modifications on this machine to improve performance. Important points are:
Speed at Sea Level with combat power        VwKC = 318 mph (512 km/h)
Speed at Sea Level with take-off power       VwKC = 327 mph (526 km/h)
Speed at full throttle height with combat power (5600 m)       VwKC = 362 mph (582 km/h)
Speed at full throttle height with take-off power (6150 m)     VwKC = 376 mph (605 km/h)
After completion of the test flights the engine, Serial No. 328909, failed due to supercharger damage and was changed. Repetition of speed performance check is therefore necessary.
3.During flight testing with the mock-up of the Panzerblitz installation it was established, that there was no significant negative impact on the flight characteristics resulting from either the slide rails rack alone, or the rack with bombs attached. The take-off with and without flaps as well as the landing with loaded installation was quite normal. In level turning flight with combat power the aircraft starts dropping a wing at Va = 265 ./. 260 km, and in horizontal flight with engine idling starts dropping the nose at Va = 200 ./. 190 (landing gear and flaps in) or Va = 172 km/h (landing gear and flaps out). In dives, where a Va = 735 km/h was reached, a slight disturbance of the ailerons was noted, at the same time a movement of the outer racks (wood) was observed. An adverse effect on the attack run, even if this phenomenon occurs with the real installation, is not to be expected.
As can be seen from the speed comparison chart, the loaded Panzerblitz installation compared to the normal condition results in a loss of speed of Δ V = 50 ./. 53 km/h with combat power. After dropping the bombs, the aircraft is about 10 ./. 11 km/h faster.
4.Several landings were recorded with the BSK 16 gun camera for use as an instructional film. The normal camera setting to R.B.A. had to be modified for this purpose to obtain the horizon reference line as well as three-point landing with the aircraft.
