What errors does an NDB suffer from?
What errors does an NDB suffer from?
NDB errors:
Interference from other NDB’s
-
Static, especially near thunderstorms
-
Night effect Coastal refraction
-
Mountain effect
-
Aircraft quadrantal error
What is the difference between angle of attack and angle of incidence?
What is the difference between angle of attack and angle of incidence?
Angle of attack is the angle between the chord of the aerofoil and the relative airflow.
Angle of incidence is the angle between the chord and the aircrafts longitudinal datum.
If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?
If you are at the locator, on glide-scope, on localiser, but your altimeter is reading 500ft high what could be the cause of this?
False glide slope.
What are the effects on the human body in case of depressurisation?
What are the effects on the human body in case of depressurisation?
Hypoxia, a lack of oxygen to tissues of the body due to low partial pressure at altitude.
Symptoms are: blue lips, apparent personality change, impaired judgement, muscular impairment, short term memory loss, sensory loss, hyperventilation, unconsciousness.
Other possible effects:
-
Baurotrauma
-
Lung damage
Is carb heat an electrical system?
Is carb heat an electrical system?
No. Carburetor heat uses exhaust air to heat air going into the carburetor. No electrics are involved.
What do the abbreviations TSRA and MIFG mean?
What do the abbreviations TSRA and MIFG mean?
TSRA: Thunderstorm with rain
- MIFG: Shallow fog
What do airplanes have to guard against reaching Mcrit?
What do airplanes have to guard against reaching Mcrit?
Barber pole on the ASI, flying at a Mach number at altitude and audible warnings.
If turboprops are more efficient aircraft, why do they not climb that high?
If turboprops are more efficient aircraft, why do they not climb that high?
Jet engines are designed to achieve their best specific fuel consumption at high rpm, which can only be achieved at high altitudes where the air density is low.
Thrust produced will be low enough to equal the required cruising thrust. Also high altitude gives the best operating conditions for the airframe i.e. minimum drag during the cruise.
Turboprops need relatively dense air for the propellers to work efficiently and at high altitude the density would be too low.
Why would someone fly a Rhumb Line track?
Why would someone fly a Rhumb Line track?
-
If no IRS/INS/GPS was available, it’s easier to fly a constant heading (but you will need to apply variation).
-
If flying over short distances (as done during your training) the error introduced by flying a rhumb line is insi
