From Category 3 Packet

• h + c = 4.55

  1.10h + 0.75c = 5

• h + c = 5

  1.10h + 0.75c = 4.55

• h + c = 4.55

  1.10h + 0.75c = 4.55

• h + c = 5

  1.10h + 0.75c = 5

• The airplane starts its descent from an altitude 500 feet lower.

• The airplane descends 500 feet per horizontal mile faster.

• The airplane descends 500 feet per horizontal mile slower.
