Final answer:
The appropriate VFR cruising altitude for a flight on a Victor Airway with a magnetic course of 175° and terrain less than 1,000 feet would be 1,500 feet or higher.
Step-by-step explanation:
The appropriate VFR cruising altitude for a flight on a Victor Airway with a magnetic course of 175° is determined by the magnetic course. In this case, the magnetic course is 175°. To determine the cruising altitude, we need to refer to the east-west rule. According to the rule, flights with magnetic courses of 0° to 179° should fly at odd thousands plus 500 feet, and flights with magnetic courses of 180° to 359° should fly at even thousands plus 500 feet.
Since the magnetic course in this case is 175°, which falls in the range of 0° to 179°, the appropriate VFR cruising altitude would be an odd thousand plus 500 feet. To calculate the specific altitude, we add 500 feet to the odd thousand below the current altitude. If the terrain is less than 1,000 feet, the possible VFR cruising altitudes would be 1,500 feet or higher to maintain the minimum safe altitude above the terrain.
Therefore, the VFR cruising altitude acceptable for this flight on a Victor Airway with a magnetic course of 175° and terrain less than 1,000 feet would be 1,500 feet or higher.
