Quiz: Cold Weather Operations

Flight Training Central

Frost will change the camber of the wing, increasing its lifting capability. Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability. To determine runway braking action, consult the: local NOTAM's MU friction value. How will frost on the wings of an airplane affect takeoff performance?

What Is Air Density? A Simple Guide for Pilots

Pilot Institute

Key Takeaways Air density affects aircraft performance, including lift, engine power, and propeller effectiveness. These include lift, propeller thrust, and engine combustion. This increased density increases airflow over the wings, generating more lift. Fewer air molecules result in less dense air, which means less lift.

How to Make a Perfect Soft Field Landing Every Time

Pilot Institute

Check NOTAMs Before departure, check the Notices to Air Missions (NOTAM) publication. You might find a NOTAM about your destination’s surface conditions. Don’t depend on NOTAMs to provide up-to-date information on soft field conditions. The sudden loss of lift can cause the wheels to dig into the ground.

PAVE Checklist Explained

Pilot Institute

Icing: Ice buildup can reduce lift and increase drag. Terrain and NOTAMs Weather isnt the only thing you have to consider. On top of that, you should always check NOTAMs (Notices to Air Missions) before your flight. What do NOTAMs do? Which aspects of the weather should you watch out for?

Dealing with volcanic ash

Professional Pilot

When an area of volcanic ash is identified, the responsible VAAC will issue a Volcanic Ash Advisory (VAA), which is disseminated to pilots as a NOTAM or SIGMET via ATC, company network operations centers (NOCs), or weather services. VAACs are responsible for monitoring volcanic activity worldwide and improving forecasts of ash hazards.

Mastering Crosswind Landings (A Step-by-Step Guide)

Pilot Institute

However, check NOTAMs for runway closures. A bounce or skip is likely if the aircraft lands while the wing is generating significant lift. Look at the airport layout and determine the winds in relation to the available runways. The runway most closely aligned to the expected wind direction will likely be active.

Evaporation of some of the rain cools the downdraft, making it even more dense compared to the surrounding air. Gust fronts are normally seen moving away from weakening thunderstorm cores.
