Final answer:
Manual controls for a Delta One seat are most commonly found on the armrest, providing passengers with easy access to seat adjustments. Some aircraft also have complementary controls on the touchscreen display.
Step-by-step explanation:
The manual controls for a Delta One seat are typically found in one of the following locations for ease of access and ergonomic convenience:
- Option 1: On the armrest
- Option 2: In the seatback pocket
- Option 3: On the touchscreen display
- Option 4: Near the galley area
However, in most Delta One cabins, you will find the manual controls for the seat primarily on the armrest. This allows passengers to adjust their seats without having to reach too far. On some aircraft, there may also be complementary controls on the touchscreen display integrated into the seatback or the remote for the in-flight entertainment system. It is uncommon to find seat controls in the seatback pocket or near the galley area, as they might be less accessible in those locations.
