11. Using the tabulation completed above, switch on all continuous electrical loads used for the
taxiing phase and record the current measured by the ammeter (measurement (a) in Figure
4-52). The autopilot circuit breaker (if installed) should be closed, but the autopilot should not
be engaged.
WARNING
Pitot heat should be switched on only long enough to take the current measurement and then
switched off to avoid injury to personnel or damage to the Pitot tube.
12. Using the tabulation completed above, switch on all continuous electrical loads used for the
normal takeoff/landing phase and record the current measured by the ammeter. Measurements
must be taken with the landing lights ON and OFF (measurements (b1) and (b2) in Figure
4-52).
13. Engage the autopilot (if installed).
14. Using the tabulation completed above, switch on all continuous electrical loads which are used
for the normal cruise phase and record the current measured by the ammeter measurement (c)
in Figure 4-52.
15. Using the tabulation completed above, switch on all continuous electrical loads used for the
emergency cruise phase and record the current measured by the ammeter.
16. Using the tabulation completed above, switch on all continuous electrical loads used for the
emergency landing phase and record the current measured by the ammeter.
17. Using the values measured and recorded, complete the ELA using the blank form in Figure
4-52 and Figure 4-53.
18. Verify the maximum electrical load does not exceed 80% of the electrical system capacity. See
example in Figure 4-54 and Figure 4-55.
NOTE
Electrical loads in excess of 80% but not greater than 95% of electrical system capacity are
permitted during the takeoff/landing phase of flight when landing light(s) are switched on.
