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.
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
Explain what coffin corner is and what happens when reaching the coffin corner?
Explain what coffin corner is and what happens when reaching the coffin corner?
Occurs at absolute ceiling where low speed buffet and high speed (Mach) buffet are coincident.
When reaching the coffin corner, both increasing and decreasing the corner speed will result in a loss of control (either the aircraft stalls, or mach buffeting starts).
What do the abbreviations TSRA and MIFG mean?
What do the abbreviations TSRA and MIFG mean?
TSRA: Thunderstorm with rain
- MIFG: Shallow fog
What will happen if the primer of your engine/fuel system kept operating?
What will happen if the primer of your engine/fuel system kept operating?
A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage, fixed pitch propellers only have a certain rpm.
How would you load an aircraft for max range?
How would you load an aircraft for max range?
The position of the CG directly influences the fuel consumption of an aircraft. An aft position of the CG makes the aircraft less stable, requiring less lift to be generated in both the horizontal stabilizer and wings, reducing the overall drag of the aircraft, and increasing the max range.
You want to load the the aircraft so that the CG is at, or as close as possible, to the aft limit (Without exceeding it).
What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?
What is ACA/H? What ACA/H did you use? Why do we have an ACA/H?
Asymmetric Committal Altitude/Height is the minimum height needed to establish a positive climb whilst maintaining adequate speed for control and removal of drag during an approach to a landing.
In the Seneca at Oxford we used 200ft AGL. At this altitude when continuing for landing you selected the landing flaps (check clear runway, on speed, on altitude, landing clearance received).
You now are committed to land, single engine G/A with flaps 40 and gear down is not possible in a Seneca.
What is windshear?
What is windshear?
Windshear is a change of wind speed and/or direction from place to place, including updraughts and down draughts.
It is ussualy characterized by a strong change over a short distance. Windshear can effect the flight path and airspeed and can be hazardous.
How does an altimeter work and which errors can an altimeter experience?
How does an altimeter work and which errors can an altimeter experience?
When an aircraft climbs, the static pressure in the instrument case decreases, which allows the enclosed capsule to expand.
This in turn moves the needle on the instrument to indicate a corresponding altitude.
During descent, the opposite function applies.
Altimeter errors can originate and vary from:
Instrument Pressure Time-lag Barometric Density Temperature Blocked static port
What does a Mach trimmer do?
What does a Mach trimmer do?
A Mach trimmer automatically compensates for Mach tuck above Mcrit.
