Heinkel HE IIIH-2 and HEIIIP-2

There are two Heinkel HE III variants. The HEIIIP-2 is powered by the DB601 and the HEIIIH-2 that is powered by the Jumo 211. The DB601 powered P-2 has the same automatic continuous step less Supercharger system as fitted to the 109. The Jumo 211 powered H-2 has a 2 stage Supercharger with Manual Supercharger Shift. Being Medium level bombers these aircraft have Low G ratings. It is relatively easy to exceed these G limits especially at the higher speeds. Consider having a dedicated Joystick sensitivity set up for these aircraft. Both these aircraft are equipped with straight out Variable Pitch props. Many features in these aircraft are identical. This guide will cover both variants with differences noted.

The Bomb aiming system is the same as the Ju88 using the lofte semi automatic bombsight. Both variants are equipped with AFN-2 gauge and are able to home on beacons and use the Lorenz approach system. The Autopilot system is essentially the same as the Ju88.

FUEL SYSTEM

The HEIII has a total of four fuel tanks 2 in each wing. These tanks are referred to as Inner and Outer tanks. Fuel Quantity indicators for both Port and Starboard tanks are located in the ceiling outboard of the pilots right shoulder. Individual selector switches are provided to allow each tank to be selected to read its respective quantity. There are a total of 4 Fuel Cocks. Two are on the Left hand sill panel (Fuel Cocks 1 &2) and two levers are located to the right of the pilots seat (Fuel Cocks 3&4). These cocks allow for tank isolation and the control of fuel transfer between tanks. Cocks 3 and 4 are used to select the Source tank and destination tank for Fuel transfers. The Long lever selects the source tank and the short lever selects the destination tank.
