Final answer:
The appropriate cruising altitude for a VFR flight on a magnetic course of 135° is odd thousandths plus 500 feet, ensuring separation between VFR and IFR traffic and maintaining aviation safety.
Step-by-step explanation:
Cruising Altitude for VFR Flight
The appropriate cruising altitude for a Visual Flight Rules (VFR) flight on a magnetic course of 135° is odd thousandths plus 500 feet. According to VFR cruising altitude rules, when flying at altitudes of more than 3,000 feet above ground level (AGL) and on a magnetic course of 0° through 179°, pilots should fly at odd thousand foot altitudes plus 500 feet. This means that if a pilot chooses to fly at 5,000 feet, they would add 500 feet, for an actual cruising altitude of 5,500 feet. This system ensures separation between VFR and Instrument Flight Rules (IFR) traffic, which uses the even thousand-foot levels (without the additional 500 feet).
The flight path of a commercial airliner is strictly regulated by the Federal Aviation Administration (FAA) to ensure planes maintain a safe distance from each other, similar to the way quantum mechanics suggests electrons have restrictions on their locations. This controlled airspace design is critical for the safety and efficiency of air travel.
