GED Reasoning Through Language ArtsReading ComprehensionHard
A pilot is reading a weather briefing report. One section states: 'Current conditions indicate widespread IFR in the mountainous regions, with isolated areas of MVFR in the valleys. Freezing precipitation is probable above 5,000 feet MSL, transitioning to snow above 7,000 feet MSL.' Based on this report, what is the most significant hazard for a pilot planning a visual flight rules (VFR) flight through the mountainous regions?
- AFreezing precipitation below 5,000 feet MSL.
- BThe transition to snow above 7,000 feet MSL.
- CIsolated areas of MVFR in the valleys.
- DWidespread IFR conditions.
Show answer & explanationAnswer & explanation
Correct answer: D. Widespread IFR conditions.
VFR flights require visual meteorological conditions (VMC). IFR (Instrument Flight Rules) conditions mean poor visibility and low cloud ceilings, making VFR flight illegal and unsafe. Widespread IFR in mountainous regions is the most significant hazard because it directly prevents VFR flight in that area, unlike MVFR which is marginal VFR, or freezing precipitation/snow at specific altitudes which are hazards but can sometimes be avoided or mitigated if VMC allows.
Why the other options are wrong
- A. The report states freezing precipitation is 'above 5,000 feet MSL,' meaning it's not probable below that altitude. (Incorrect)
- B. Snow at 7,000 feet MSL is a hazard, but the widespread IFR at all altitudes in the mountainous region is a more fundamental barrier to VFR flight. (Incorrect)
- C. MVFR (Marginal VFR) conditions are challenging but do not strictly prohibit VFR flight; IFR is a complete prohibition. (Incorrect)
VFR Weather Minimums
Specific minimum visibility and cloud clearance requirements that must be met for a pilot to legally and safely fly under Visual Flight Rules (VFR).
- VFR requires pilots to 'see and avoid' other aircraft and obstacles.
- Conditions are categorized as VFR, MVFR, IFR, or LIFR.
- IFR conditions mean VFR flight is prohibited.
Memory trick: VFR: Very Fine for flying; IFR: Instruments are For Required.
