Rare PBY Catalina, General Electric Type DJII Flap Position Indicator

Manufactured by General Electric, this rare Type DJII WWII Flap Position Indicator was installed in the US designed Consolidated Catalina, long distance patrol flying boat.

The PBY Consolidated Catalina had extended wing flaps which were controlled by the co-pilot under direction from the pilot.

The indicator provided visual information on the angle of extension of the wing flaps during take-off and landing, measured from ‘Full Up' at 0 degrees to 40 degrees ‘Fully Extended Downward'. 

Preparing for takeoff the copilot would extend the wing flaps to the 20 degree down position which would be the maximum setting for takeoff lift.

Holding the operating lever in the down position until the aircraft was airborne, once the copilot released it the wing flaps would automatically return to the neutral position.

One of the constant challenges for pilots of the Catalina and the British Short Sunderland seaplanes, was breaking the surface suction that built up against the bottom of the hull as the aircraft increased its take off speed through the water.

Aeronautical engineers had long recognised the problem of surface suction and had designed a small ’step’ midway down the hull of the aircraft to lessen the suction effect but it still required a significant effort from the pilot to break its hold.

Often the pilot would weave the aircraft side to side on takeoff, cutting across any ocean chop in an attempt to break the surface suction. In fact it was often easier getting the 35,420 lb Catalina into the air in rough conditions than if the water was glass smooth.


Given the extraordinary takeoff length required by the Catalina and even more so, the Short Sunderland to get airborne, it was not uncommon for the pilots to make two or three attempts to get airborne after running out of water in calm conditions.

Landing in calm conditions was often no easier with it being almost impossible to accurately gauge the aircraft’s hight off the mirrored water surface.

Land with the nose too far down and the aircraft was instantly gripped by the water, pitching the Catalina violently forward. 

Land with the nose too far up and the tail hitting first and the aircraft would suddenly porpoise, pitching the nose skyward and threatening to flip the aircraft over onto its back as the lift suddenly developed at the wings whilst the water held the tail down.

This General Electric Type DJII PBY Catalina Flap Indicator is a rare collectable of an iconic aviation veteran of WWII.
