810. LOST COMMUNICATIONS

For the following examples, use the procedures contained in the Flight Information Handbook,

Section A. Additionally, you will need to view the Low Altitude Chart 18, panels E, F and G.

Assume that two pilots have filed an IFR flight plan from NAS Whiting Field to Marianna

Municipal Airport and the route of flight reads "direct to Crestview VORTAC, V198 to

Marianna VORTAC." If ATC cleared the flight "as filed" and the pilots had two-way radio

failure in IFR conditions in the vicinity of Corky (CORKY) Intersection, they would proceed to

Marianna VORTAC via V198 according to the last ATC clearance.

Let's develop the example in the above paragraph a step further. Assume the pilots filed the

flight plan similarly, but ATC only gave a short range clearance and cleared them to Chews

(CHEWS) Intersection via V198. Chews Intersection is now the clearance limit. If the pilots

had two-way radio failure in IFR conditions in the vicinity of Corky (CORKY) Intersection, they

would proceed to Chews (CHEWS) Intersection according to the ATC clearance and then

proceed to Marianna VORTAC according to the filed flight plan.

Developing the example one more step, assume that the pilots again filed the same flight plan.

This time, however, ATC cleared the pilots as follows: ". . .cleared direct to Crestview VORTAC

V241 To Dared (DARED) Intersection. Expect further clearance direct to Marianna VORTAC.

In this case, the short range clearance limit, Dared (DARED) Intersection, is not on the filed

flight plan.
