CASR.
TLOF means touchdown and lift-off area and is the surface over which the touchdown and lift-off is conducted.
transition altitude means the altitude at or below which the vertical position of an aircraft is controlled by reference to altitudes.
transition layer means the airspace between the transition altitude and the transition level.
transition level means the level at or above which the vertical position of an aircraft is controlled by reference to flight levels.
transponders and surveillance equipment: see subsection 1.07 (7).
trip fuel means the amount of fuel required to enable an aircraft to fly from any point along a route until landing at a destination aerodrome including (as applicable) the following:
(a) fuel for take-off and climb from departure aerodrome elevation to initial cruising level or altitude, taking into account the expected departure routing;
(b) fuel for cruise from top of climb to top of descent, including any step climb or descent;
(c) fuel from top of descent to the point where the approach is initiated, taking into account the expected arrival procedure;
(d) fuel for executing an approach and landing at the planned destination aerodrome.
TSO is short for Technical Standard Order of the FAA: see the CASR Dictionary.
Type A, for an instrument approach operation, means a minimum descent height, or a decision height at or above 250 ft.
Type B, for an instrument approach operation, means a decision height below 250 ft, and includes CAT I ILS and low-visibility CAT II and CAT III ILS.
Type 2 DAT approval means an approval issued by EASA that authorises the supply of aeronautical databases for which aircraft compatibility has been demonstrated.
Type 2 LOA means an LOA issued by the FAA or EASA that identifies the compatibility of its delivered data with a particular avionic system or avionic systems.
unforeseen factors means factors that could have an influence on an aircraft's fuel consumption to the planned destination aerodrome, including the following:
(a) the aircraft's deviation from the expected fuel consumption data for an aircraft of the same type;
(b) extended delays and deviations from planned routings or cruising levels.
use NVIS means to use NVIS as the primary means of terrain avoidance for safe air navigation by means of visual surface reference external to the aircraft.
valid, for a navigation database: see section 14.07.
VAT, or velocity at threshold, for this MOS, means the indicated airspeed at the threshold which is equal to the higher of whichever of the following is available in the landing configuration at the maximum certificated landing mass:
(a) stall speed VSO multiplied by 1.3; or
(b) stall speed VS1G multiplied by 1.23.
VFR, or visual flight rules, and has the meaning
