Can VMCG be lower than V1? Explain.
Can VMCG be lower than V1? Explain.
Yes, VMCG has to be equal to or less than V1 to ensure the aircraft could maintain runway heading having suffered an engine failure at or above V1 when the aircraft is committed to takeoff.
What is density altitude? and what is pressure altitude?
What is density altitude? and what is pressure altitude?
Density altitude is pressure altitude corrected for temperature.
Pressure altitude is the indicated altitude when an altimeter is set to 29.92 (1,013.2 mb).
Describe the take off segments.
Describe the take off segments.
1st segment starts at screen height and finishes at gear retracted.
2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.
3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.
4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.
What setting would you set the trim to for long range cruise?
What setting would you set the trim to for long range cruise?
Nose up
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
5000 litres
(4 tonnes / 0.8 = 5000 litters)
What is the environmental lapse rate according to ISA?
What is the environmental lapse rate according to ISA?
1.98°C per 1000ft
What is an FMA used for?
What is an FMA used for?
Bright yellow lights will light up in the cockpit.
Why is anhedral used instead on some aircraft?
Why is anhedral used instead on some aircraft?
Anhedral:
compensates for the wing sweep improves roll maneuverability
Why do we measure speed as a Mach number?
Why do we measure speed as a Mach number?
Mach number describes the speed of sound, which changes with the density of the medium it is travelling through.
When you reach the speed of sound, the compressibility effect creates a supersonic flow along the wing if you exceed a certain mach number.
This causes airflow separation and flutter.
It is therefore much safer and much easier to use a Mach number to express a limit at which compressibility effects start to tear the aircraft apart, as it is a constant value at all altitudes.
How does GPWS work?
How does GPWS work?
GPWS is a central computer system that receives various data inputs on configuration, (radio altimeter) height/altitude and instrument landing system glide slope deviation and is able to alert the pilot when a dangerous situation is about to occur.
