SECTION 3

EMERGENCY PROCEDURES

 MOTOR FAILURE

o Operation is possible with one motor/ESC/propeller failure

 The two adjacent motors/ESCs will be increased in thrust automatically by the flight

controller to overcome the loss

 In cases where the airframe is highly loaded the maximum rating of 40 amps may be

exceeded by these two motors/ESCs

 Operation should be terminated as soon as possible to reduce the possibility of damage

to the remaining motors

 COMMUNICATION FAILURE

o Video link failure

 5.8 Ghz being the shortest wavelength in general AV use has the least ability to

penetrate. This link should be the first to be lost.

 It is best to lose video first! It is the least likely to cause a crash when it fails.

 5.8 Ghz can lose link with little warning.

 Ensure that the GCS station antennas are perpendicular to the AV. Do not point the

antenna at the AV.

 Yaw the AV to change the antenna position

 Other links should still be good. Return back to the GCS until link is restored.

 Transmitters produce heat when in operation. When overheated they may have

thermal protection which interrupts use temporarily. Use of a heat sink or fan may be

required especially with high ambient temperatures.

 Higher gain antennas may be used, but do so with caution. High gain antennas are

directional.

 Multiple antennas using “diversity” can be used. Diversity is a device which

determines the best signal, and uses that.

 5.8 Ghz even at high wattages theoretically has less range than lower frequencies.

Changing to 1.3 Ghz is an option, though there are other issues to be considered.

o RC link failure

 2.4 Ghz antennas can lose link with little warning.

 Anything in between the two antennas can cause temporary signal loss especially a

person.

 Hold the transmitter up in the air and walk in the general direction of the AV (aerial

vehicle).

 Ensure that the antenna is vertical. Do not point the antenna at the AV.

 The failsafes on the RC link should be set so that the AV returns to home. Should this

require a heading change, the antenna may move into a more desirable position and

link will be restored.

 The onboard equipment may block the signal. Yaw the AV so that the antennas point

towards the GCS.

 A LRS (long range system) can be used as a permanent solution. This is higher in

wattage and usually on 433 Mhz.

o Data Link Failure

 900 Mhz do not lose link without some warning. When drop outs are noticed to

increase in frequency that is the limit of the range.
