What is the maximum altitude to reach over Hw 45 when taking off from runway 13R (VFR)?

• A. 1,200' MSL
• B. 3,500' MSL
• C. 5,000' MSL
• D. 10,000' MSL

Answer: (B)

In this scenario, the maximum altitude to reach over Highway 45 when taking off from runway 13R under Visual Flight Rules (VFR) is set at 3,500 feet Mean Sea Level (MSL). This altitude is consistent with common VFR departure procedures which aim to ensure safe separation from both ground obstacles and other traffic while also adhering to airspace regulations.

When departing from a runway, especially in an area with surrounding features such as highways and urban environments, it is vital to maintain an altitude that provides a margin of safety from potential obstacles, as well as to comply with any local air traffic control instructions or memorized procedures. The choice of 3,500 feet MSL is typically a standard altitude that balances these safety concerns with operational efficiency.

Additionally, this altitude helps ensure that aircraft remain clear of any controlled airspace that might be adjacent or above the departure route. Generally, lower altitude thresholds like 1,200 feet would not provide sufficient safety margins for obstacle clearance in many flight scenarios, while 5,000 and 10,000 feet MSL would typically be above what is necessary for VFR departures in such areas and might lead to regulatory or operational challenges.

Understanding these aspects helps pilots make informed decisions about maximum
