How can you calculate Vref?
How can you calculate Vref?
Vref = 1.3 x Vs0 (stall speed in the landing configuration).
What’s the temperature at FL150 according to ISA?
What’s the temperature at FL150 according to ISA?
-15°C
because:
-2°C per 1000 feet gives -30°C.
ISA: 15°C at sea level - 30°C = -15°C at FL150
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
Via INS/IRS/GPS
What is the cabin altitude of the Boeing 737 on a cruise flight level?
What is the cabin altitude of the Boeing 737 on a cruise flight level?
8.000ft
What is dihedral?
What is dihedral?
Dihedral is the upward inclinitation of the wing from the root to the tip.
What is a Rhumb Line?
What is a Rhumb Line?
A line across the surface of the earth that cuts all meridians at the same angle. i.e. a track of constant direction.
A straight line on a Mercator chart.
Do single engined planes have a VMCG?
Do single engined planes have a VMCG?
No, VMCG is defined as the minimum control speed on the ground, with one engine inoperative (critical engine on two engine airplanes), takeoff power on other engine(s), using aerodynamic controls only for directional control and thus only applicable to ME aircraft.
How does an airspeed indicator work and which errors can an airspeed indicator experience?
How does an airspeed indicator work and which errors can an airspeed indicator experience?
The airspeed indicator uses part of the aircraft's pitot-static system to measure and compare the dynamic air pressure between air moving into the pitot tube and static air pressure measured in the case.
The ASI is calibrated to ISA at MSL and represents the dynamic pressure as indicated airspeed in knots per hour.
ASI errors can originate and vary from:
Instrument Pressure Density Compressibility Maneuver Blocked pitot static system

If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
TAS will increase.
