Clearance Density Altitude Rudder

The calculated density altitude was 4,790 feet. Probable cause(s): The pilot’s failure to maintain clearance from trees after takeoff, during high density altitude weather conditions. The pilot applied right rudder in an attempt to correct this, resulting in a ground loop.

Temperature An increase in temperature will increase the density altitude. A high density altitude decreases the performance of the engine and the wing. Your aircraft will fly at a faster true airspeed at higher density altitudes. This can greatly impact landing performance and obstacle clearance.

Improve your stick and rudder skills as a private pilot go beyond the instrument checkride with these advanced courses. The app includes 65 airports and hundreds of potential scenarios, so you can practice getting an IFR clearance at a Class D airport, talking to tower at a Class C airport, or making position reports at a non-towered airport.

It was 87° F, a density altitude of 7300 feet and we ended up with four people, 120 gallons plus baggage, and we got off in 2400 feet with naturally aspirated engines. An elegantly simple rope system inside the fuselage raises and lowers the Gweduck’s water rudder mounted inside the base of the main rudder (right).
