About the M-1H
A main-deck upper contoured container built to the AMD code, shaped to follow the upper fuselage profile.
The contour is what separates it from the rectangular M-1: it fills the space above the shoulder of the main deck where a square unit cannot go. At the same weight rating it carries 21.2 m³ against the M-1's 17.6 m³.
What it carries
How it is built
- A main-deck container with an upper contour, shaped to the crown of the fuselage.
- The door is canvas, carrying built-in net door straps.
- A heavier structural section than lower-deck equipment, sized to fill the main cargo deck of a freighter or Combi.
- Rectangular or upper-contoured in profile, depending on where in the deck the unit is positioned.
- A solid or canvas door with net straps, and base rails matched to the main-deck restraint system.
Why it is used
- Far higher gross weight and volume per unit than any belly-hold ULD.
- Loads through the main cargo door in one lift, which is what makes freighter turnarounds fast.
- Suits dense or bulky consignments that would otherwise need several lower-deck units.
What to check before booking
- Loadable only on freighters and Combi aircraft that have a main-deck cargo door.
- Some positions accept centre loading only, which limits where the unit can be placed.
- Handling needs main-deck loaders, so not every station can accept it.
