A C-5 aircraft with a crew of 10 will fly a three-hour mission with ramp fuel of 93,000 lbs. The basic aircraft weight is 367,500 lbs. What is the Allowable Cabin Load (ACL) for this mission?

To determine the Allowable Cabin Load (ACL) for the mission of a C-5 aircraft, we'll use the formula to calculate it. The ACL is the weight available for cargo, passengers, and crew after accounting for the fuel and the aircraft's basic weight. Let's break down the steps:

Determine the Maximum Takeoff Weight (MTOW):
Unfortunately, the problem does not specify the MTOW. Typically, the MTOW for a C-5 Galaxy aircraft is around 840,000 lbs. However, ensure to use the correct MTOW for the specific aircraft being considered if different.
Calculate the Total Weight on Board Before Cargo:
- Basic Aircraft Weight (BAW): 367,500 lbs (as given)
- Ramp Fuel Weight: 93,000 lbs (as given)
- Crew Weight: A typical estimate for the weight of a crew member (including clothing and gear) is around 200 lbs. Therefore, for 10 crew members, this would be 10 x 200 = 2,000 lbs.
Total Weight Before Cargo = BAW + Ramp Fuel Weight + Crew Weight
[tex]367,500 + 93,000 + 2,000 = 462,500 \text{ lbs}[/tex]
Calculate the ACL:
Subtract the Total Weight Before Cargo from the MTOW to get the ACL.
[tex]\text{ACL} = \text{MTOW} - (\text{Total Weight Before Cargo})[/tex]
[tex]\text{ACL} = 840,000 - 462,500 = 377,500 \text{ lbs}[/tex]

Therefore, the ACL for this mission is 377,500 lbs. This is the maximum weight allowed for additional passengers, baggage, and cargo.
