Unit 4 Flashcards
Aircraft
device that is used for flight in the air
Airplane
engine-driven fixed-wing aircraft that is supported by wings
Air traffic control (ATC)
service to promote safe, orderly, and expeditious flow of air traffic
Category
broad classification of aircrafts (transport, utility, acrobatic…)
Class
classification of aircraft within a category (single-engine, multi-engine, helicopter…)
Ceiling
height of lowest layer of clouds above Earth’s surface
Controlled airspace
airspace of defined dimension which ATC service is provided
Decision height (DH)
height above ground level (AGL) where the decision to continue or abandon approach must be made (instrument)
Flight plan
specified info relating to intended flight that is filed orally or in writing with ATC
Flight time
time between aircraft moves under its own power → comes to rest after landing
Large aircraft
max takeoff weight of +12,500 lb
Maintenance
inspection, overhaul, repair, and preservation of the aircraft & replacement of parts
Major alteration
alteration that might affect weight, balance, strength, performance, flight… of an aircraft
Manifold pressure
absolute pressure as measured in the induction system (expressed inches of mercury)
Minimum descent altitude (MDA)
lowest altitude where a descent is authorized on final approach (expressed in ft above mean sea level)
Night
time between end of evening civil twilight → beginning of morning civil twilight
(1h after sunset to 1h before sunrise)
Non Precision approach procedure
standard instrument approach with no electronic glide slope
Pilotage
navigation by visual reference to landmarks
Pilot in command (PIC)
person who has final authority, hold appropriate category/class/type rating, was designated PIC before flight
Positive control
control of all air traffic, within designated airspace by ATC
Precision approach procedure
standard instrument approach with an electronic glide slope
Small aircraft
max takeoff weight less than 12,500 lb
AFM
airplane flight manual
AGL
above ground level
