Why is it important to consider tape stack height when selecting a site for the MRES?

Considering tape stack height when selecting a site for the MRES (Mobile Rack External Storage) is crucial because insufficient runout can pose a significant danger to the aircraft. If the tape does not have enough height, it may prevent the aircraft from safely maneuvering in and out of the area, which could result in accidents or damage to the aircraft or equipment.

Runout refers to the distance the aircraft needs to effectively engage or disengage from the tape. If the tape stack is too low, it compromises the necessary clearance, leading to potential hazards during operation. This consideration is essential to ensure that the aircraft can operate safely without encountering any obstacles or risks associated with inadequate tape height, ultimately enhancing the safety and efficiency of ground operations.
