What does the attitude indicator indicate?
The attitude indicator (AI), formerly known as the gyro horizon or artificial horizon, is a flight instrument that informs the pilot of the aircraft orientation relative to Earth’s horizon, and gives an immediate indication of the smallest orientation change.
Can you fly VFR without an attitude indicator?
No. Just the removal maintenance needs to be signed off and the inop indicator shown removed per 91.213. As long as you verified it’s not needed for flight you should be ready to go.
What does attitude mean in aviation?
[Figure 3-1] Attitude is the angular difference measured between an airplane’s axis and the line of the Earth’s horizon. Pitch attitude is the angle formed by the longitudinal axis, and bank attitude is the angle formed by the lateral axis.
What is ND in aviation?
The Navigation display screen displays the lateral navigation status of the aircraft. NDs are the evolutions of the EHSI (Electronic Horizontal Situation Indicator) and implemented for the first time in the 90’s on A320 and B737 aircraft.
What is a CAS message?
The crew-alerting system (CAS) is used in place of the annunciator panel on older systems. Rather than signaling a system failure by turning on a light behind a translucent button, failures are shown as a list of messages in a small window near the other EICAS indications.
Is attitude indicator required?
An attitude indicator installed in accordance with this AC must be located within the pilot’s primary field of view. The slip/skid indicator required by section 91.205(d)(4) must be permanently mounted on the panel or on a flight instrument within the pilot’s primary field of view.
Is attitude indicator required for VFR?
An Attitude Indicator is Not required for daytime VFR flight unless it (attitude indicator) is part of the plane’s unique “Minimum Equipment List”. Rules for aviation in the United States are spelled out in the “FAR/AIM” documents.
