TDA – Underfloor infrastructure solutions for feeding aircraft at airports
Made in France 
PIT SYSTEM
TDA is the world leader in underfloor infrastructure solutions for airports.
PIT SYSTEM systems adapted for fast connection of heating/cooling pipes and 400Hz electricity.
Installed in over 180 airports across Europe.
SUITABLE FOR AIRBUS AND BOEING AIRCRAFT AND MILITARY AIRPORTS
A company with 60 years of experience and extensive experience.
All tariffs have an EN-124 standard adapted to the F900 load for airports.
B-PIT
400Hz aircraft power feed
The B-PIT opens with a simple push of a button and allows singing access, all power cables in the B-PIT are located near the aircraft which makes it possible to connect easily and quickly. At the parking station of the aircraft, for power supply of 400 Hz or 50 Hz (up to 250 A).
Once all cables are connected, the pit can work in a closed position (there is no access into the pit). Holds up to 2 cables.
It is possible to connect in B-Pits in parallel delivery to various services.
FLEX PIT
FLEX-PIT allows aircraft to be connected to a 400 Hz power supply and all other utilities in hangars for maintenance.
The “pop out” system simplifies access to cables and sockets by raising them 50 cm above the ground.
Once all cables are connected, a hatch pit can work in closed mode.
Load resistance by: (T 90) class F900 124 EN
PCA PIT
Air conditioning for PCA PIT aircraft
The unique PCA pit design provides optimal pipe storage, easy access to the connecting device and maximum pipe protection.PCA pitsare available for all pipe technologies. PCA
Upon opening the pit, the connection point to the aircraft is displayed above the ground, at hand level.
Characteristics of the pit
POP OUT PIT
The POP OUT Pit is the optimal solution for storing and protecting a 400Hz aircraft feed cable.
Provides easy pit and cable care. In the closed state, a uniform level with the ground.
An aircraft grounding cable can also be integrated.
The lifting mechanism is operated by counterweights and is not affected by temperature changes.
The opening mechanism is regulated by gas springs, allowing smooth and effortless opening and closing.
Full sealing against water and sand penetration into the cistern in both closed and open positions.
