11.0 Definitions
11.1 Aircraft Flight Manual (AFM)
A document for each individual aircraft that contains the information necessary to operate that aircraft at the
level of safety established by the applicable airworthiness requirements, with any additional instructions and
information necessary. The certificated flight manual for the aircraft type forms the basis of the AFM, plus
any other applicable amendments or supplements. Certain portions of a manufacturer’s Pilot Operating
Handbook (POH) may be approved as the AFM.
11.2 Light Sport Aircraft (LSA)
Light Sport Aircraft (LSA) regulations introduce a new category of aircraft. The category covers various types
of sport aircraft for take off weights up to 600 kilograms (650 kgs for floatplanes). The regulations apply to
both production built aircraft and kit built aircraft. Specification F2245
11.3 Speeds
11.3.1 Airfield Pressure Altitude
The Airfield Pressure Altitude is that altitude registered at the surface of the aerodrome by an altimeter
with the pressure subscale set to 1013 millibars
11.3.2 Indicated Airspeed (IAS)
Indicated airspeed, which is the reading obtained from an airspeed indicator having no calibration error
11.3.3 Take Off Safety Speed
The Take Off Safety Speed is a speed chosen to ensure that adequate control will exist under all
conditions, including turbulence and sudden and complete engine failure, during the climb after takeoff
11.3.4 Landing Safety Speed
The Landing Safety Speed is the speed chosen to ensure that adequate control will exist under normal
conditions, including turbulence, to carry out normal flare and touchdown
11.3.5 Normal Operating Speed
This speed shall not normally be exceeded. Operations above the Normal Operating Speed shall be
conducted with caution and only in smooth air
11.3.6 Maneuvering Speed (VA)
Maximum for maneuvers involving an approach to stall conditions or full application of the primary flight
controls
11.3.6 Maximum Flap Extended Speed (VFE)
The highest speed permissible with wing flaps in the extended position
11.3.7 Maximum Structural Cruising Speed (VNO)
The speed that should not be exceeded except in smooth air, and then only with caution
11.3.8 Never Exceed Speed (VNE)
The speed limit that may not be exceeded at any time
11.3.9 Stalling Speed (VSO)
The stall speed or minimum steady flight speed at which the airplane is controllable in a specified
configuration
11.3.10 Landing Configuration
Configuration at the most forward centre of gravity
11.3.11 Best Angle-Of-Climb Speed (VX)
The speed which results in the greatest gain of altitude in a given horizontal distance
11.3.12 Best Rate-Of-Climb Speed (VY)
The speed which results in the greatest gain in altitude in a given time
