What is a METAR?
What is a METAR?
A METAR is an observation of the actual weather given by a meteorological observer at that aerodrome.
What is a Great Circle?
What is a Great Circle?
A line of shortest distance between two points on a sphere.
What is rate of climb/descent?
What is rate of climb/descent?
It's vertical velocity of the aircraft usually expressed in feet per minute.
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
The speed is too low for an indication.
What frequency range and band is an NDB in?
What frequency range and band is an NDB in?
Frequency range from 200-1750kHz, medium and low range frequency bands.
Why do jet aircraft fly as high and fast as possible?
Why do jet aircraft fly as high and fast as possible?
Because the air is less dense thus the TAS is higher for a given power setting and for this reason modern jet aircraft are designed to be most efficient at high altitude.
What is the range of a VOR at 32000ft?
What is the range of a VOR at 32000ft?
Range = 1.23(√H1 + √H2)
= 1.23 * √32000
= 220 nm
What is VMBE?
What is VMBE?
The maximum brake energy speed.
It is a function of the gross weight, altitude, temperature, runway slope, wind component, and braking configuration.
V1 must be less than VMBE.
How accurate are NDB's?
How accurate are NDB's?
NDB’s are stations emitting a signal. There is nothing for them to be accurate about. ADF's on the other hand, when tuned to an NDB need to be accurate within +/- 5 degrees.
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.
