QUESTIONImproper loading of an aircraft reduces its efficiency in terms of

  1. Aengine time between overhauls and oil consumption
  2. Bradio range and navigation accuracy at altitude
  3. Cceiling, rate of climb, and speed
Show the answer and explanation

Correct answer: C. ceiling, rate of climb, and speed

  • A — incorrect These are engine maintenance factors; the handbook's list concerns aircraft performance.
  • B — incorrect Avionics performance is unrelated to weight and balance; the losses are in flight performance.
  • C — correct The handbook lists ceiling, maneuverability, rate of climb, speed, and fuel consumption as the efficiency factors reduced by improper loading.

BACKGROUND

The maximum weight of an aircraft is based on the amount of lift the wings or rotors can provide under the operating conditions for which it is designed, and taking off and landing at lower airspeeds is safer than doing so at higher speeds. Beyond safety, weight and balance affect efficiency: improper loading reduces the efficiency of an aircraft from the standpoint of ceiling, maneuverability, rate of climb, speed, and fuel consumption. A nose-heavy airplane, for example, needs higher tail forces, which add drag and demand more power and fuel.

STUDY TIP

Memorize the five efficiency factors: ceiling, maneuverability, rate of climb, speed, and fuel consumption.

KEY POINTS

  • Maximum weight is based on the lift the wings or rotors can provide.
  • Improper loading reduces ceiling, maneuverability, climb, speed, and fuel efficiency.
  • Safety is the primary concern; efficiency is the second.
