In VFR without GPS, which should be avoided?

• A. Entry into controlled airspace without clearance
• B. Flying into cloud
• C. Climbing above 18,000 ft
• D. Deviating from planned route

Answer: (A)

In VFR without GPS, the most critical constraint to respect is airspace classification and the requirement for ATC clearance to enter controlled airspace. Without GPS, you’re relying on charts, ground references, and pilotage, which makes it easier to misjudge your position relative to airspace boundaries. Entering controlled airspace without the proper clearance can put you in conflict with other traffic and with ATC, and it’s illegal. That combination of regulatory obligation and safety risk is why this action should be avoided. Flying into cloud is also something to avoid under VFR because you must remain clear of clouds to maintain visual flight rules, but the scenario emphasizes the airspace clearance aspect as the primary risk when navigating without GPS. Climbing above 18,000 feet would generally require different rules and equipment (and would push you into a different airspace regime), and deviating from the planned route, while not ideal, is not inherently as critical a safety/legal issue as entering restricted airspace without clearance.
