Fichas del conjunto (14)
- 1Flying with no change in surface pressure of datum point in warm to cold air?You will descend
- 2How many feet per hpa?27 ft/hpa
- 3Is cold air more or less dense?Colder air denser, warmer air less dense
- 4Important to remember ("watch out below")?"High to low watch out below"
- 5Altimeter temp error correction?4% for every 10C deviation from ISA (- if colder + if warmer)
4% x (ISA dev /10) x alt - 6What occurs if the alt subscale is unchanged but the ground surface pressure changes?Will climb or descend depending on the change of pressure relative to the subscale
- 7SPSStandard Pressure Setting of 1013
Also called pressure altiude - 8If QFE set on landing and a pressure drop overnight?It will seem like an apparent climb on the altimeter
- 9Height?Vertical distance of a level or point from a specific datum (e.g. above ground level)
- 10Altitude?Vertical distance above sea level
- 11Slight difference between Pressure Altitude and FL?Pressure Alt in 1000s of feet, FL in 100s of feet
- 12Transition Altitude?Point at which you switch from QNH to the SPS. Fixed by the state
- 13Transition Level?Point at which you change from SPS to the local QNH. Level varies day to day and is set by ATC
- 14When stationary what happens to true alt and pressure altimeter indication?True alt will remain the same as you are stationary though the pressure altitude indication will vary
