8. Determine the position of landing gear by checking the gear
position light and the mirror on the right side of the left cowl.
9. To prevent tripping the overheat lockout switch and to get
best service life from the heater components, it is recommended that
the heater switch be turned to "FAN" just prior to landing. This will
allow adequate cooling during ground operation.
10. Remember that when the post lights are on, the gear position
lights are very dim.
11. Before starting the engines determine that all radio switches,
light switches, and the pitot heat switch are in the off position so as not
to create an overloaded condition when the starter is engaged.
12. The trim tab on the Aztec is very responsive and a small
adjustment in trim control gives a rapid trim change attitude.
13. A high fuel pressure indication on the fuel flow indicator is a
possible indication of restricted airbleed nozzles.
14. When flying in icing conditions' at high altitudes the engine
ram air filter can flash over with impact ice. The alternate air doors will
open and an asymmetrical manifold pressure drop may occur.
15. In anticipation of gust load conditions when operating near
zero fuel gross weight, carry fuel in the outboard tanks and distribute
cargo according to the Flight Manual and Weight and Balance form.
Regarding increased payloads, cargo weight is not approved in excess of
passenger and seat weight displaced .
. 16. The shape of the wing fuel tanks is such that in certain
maneuvers the fuel may move away from the tank outlet. If the outlet
is uncovered, the fuel flow will be interrupted and a temporary loss of
power may result. Pilots can prevent inadvertent uncovering of the
outlet by having adequate fuel in the tank selected and avoiding
maneuvers which could result in uncovering the outlet.
Normal takeoffs are not to be made when the tank selected is
less than one-quarter full.
Running turning takeoffs should be avoided as fuel flow
interruption may occur when the tank selected is less than half full.
Prolonged slips or skids in any pitch attitude or other unusual
or abrupt maneuvers which could cause uncovering of the fuel outlet
must be avoided when the tank selected is less than half full.
