|
| Tight engine cowling.
|
| Split flaps.

| Armament: 2 MG 151
|
| Autopilot.
|
| Variometer installation

| Robotic system.
|
| Auxiliary wing tanks with standard Ju 87 rack fairing, or two faired ETC 50 each wing in accordance with 8-190862-Z01
|
| ETC 501 under the fuselage with ER 4 lock 50 L 2
|
| Program: |
| 1. |
Check the auxiliary wing tank system.
|
| 2. |
Level speeds for various operational conditions with ETC 50 or bomb locks.
|
| 3. |
Assessment of the instrument panels.
|
| 4. |
Ram pressure calibration on the test course.
|
| Results: |
| 1. |
The re-check of the fuel flow from the auxiliary wing
tank gave 960 l/h. The pump limiter responded at 285 liters indicated
in the rear tank. It is noted in this context that in some cases the
pump limiter reopens only at 245 liters in the rear tank, so that the
auxiliary tank pumps must be switched off only after the indicator
shows less than 240 liters. |

With regard to flying characteristics, no objections were found in all conditions.

|
|
| 3. |
The variometer
installation is not working properly, that device cannot be read between
+2 and -4 m/sec, as this area is hidden by the Revi.
The clock installed in parallel to the right cockpit wall can also not be read between 13 to 14 clock.
