Continue to fly in VMC or IMC, proceed to land at an aerodrome that provides radar services.

Continue to fly the flight planned route, hold at the initial approach fix until the estimated approach time, then proceed to commence an instrument approach at the destination aerodrome.

Continue to fly in VMC, proceed to land at the nearest suitable aerodrome and report the arrival to the appropriate Air Traffic Services unit as soon as possible.

it allows Na⁺ and K⁺ concentrations to re-equalize at points that have already produced APs.

APs can generally travel in only one direction along the neuron.

it allows electrotonic current spread from one point to the next along the neuron.

it allows neurons to respond even to a second stimulus presented 1msec after the first one.

it allows the AP threshold to recover.

30 minutes after ETA or the last EAT, whichever is later.

30 minutes after noticing the radio failure.

15 minutes after vacating the transition layer.

30 minutes after waiting for the EAT.
