Aircraft

Q-Corner – Coffin Corner

Q-Corner or Coffin Corner is a term used to describe operations at high altitudes where low indicated airspeeds yield high true airspeeds (MACH number) at high angles of attack. The high angle of attack results in flow separation which causes buffet. Turning maneuvers at these altitudes increase the angle of attack and result in stability [...]

MACH – Various MACH Related Definitions

MACH – Various MACH Related Definitions

MACH -Named after Ernst Mach, a 19th century Austrian physicist, is the ratio of an aircraft’s true speed as compared to the local speed of sound at a given time or place.
MACH number (MACH Speed) is a decimal number (M) representing the true airspeed (TAS) relationship to the local speed of sound (e.g., TAS [...]

TCDS - Type Certificate Data Sheets

TCDS – Type Certificate Data Sheets

 

 
Type Certificate Data Sheets- Type Certificate Data Sheets (TCDS) are a part of the Type Certification Process and contain information relevant to the certification of particular aircraft. TCDS contain information that is useful, not only at the time the aircraft undergoes certification, but as an ongoing resource for the life of an aircraft. Any time a Certificate of [...]

Flight Director - FD

Flight Director – FD

Electronic Flight Directors display cues to guide pilot or autopilot control inputs along a selected and computed flight path. The Flight Director receives inputs such as altitude, airspeed heading data and temperature data. The Flight Director receives information from an Air Data Computer and a flight data computer

Accelerate-stop distance

Accelerate-stop distance

Accelerated Stop Distance is the distance required to accelerate to V1 with all engines at takeoff power, experience an engine failure at V1, and abort the takeoff and bring the airplane to a stop using braking action only and not reverse thrust. Here is a video undergoing an Accelerate Stop Test during certification

Mean Aerodynamic Chord - MAC

Mean Aerodynamic Chord – MAC

Mean Aerodynamic Chord – MAC- In relation to the aerodynamics of a wing, the average length of the chord on tapered swept-back wings is known as the mean aerodynamic chord (MAC). Business jets and commercial transport airplanes have wings that are tapered and that are swept back, so the width of their wings is different along their entire length. The width is greatest where the wing meets the fuselage and progressively decreases toward the tip.

Visual Docking Guidance Systems (VDGS)

Visual Docking Guidance Systems (VDGS)

Visual Docking Guidance Systems (VDGS), sometimes referred to as Nose-in Docking Guidance Systems or Stand Entry Guidance Systems (SEG), provide guidance where accurate aircraft parking is required.
This is usually the case where Jetways /airbridges are used. The AGNIS VDGS  currently in use in many major airports in the world  include Azimuth Guidance for Nose-in Stands (AGNIS), supported by [...]
