Report 200 feet prior to DH or MDA and arrival at MDA/DH

CHAPTER FIVE

T-6A INSTRUMENT NAVIGATION

verbiage "increase rate of descent" if above the glidepath or "decrease rate of

descent" if below the glidepath.

Descend to MDA. On an ASR approach, upon controller instruction, direct a descent

to MDA. Ensure rate of descent utilized is sufficient to arrive at the MDA prior to the

MAP.

NOTES

1. If receiving recommended altitudes, remember that they are

advisory in nature. They should be used as a guide to give an idea

if you are on a proper descent path to arrive at the MDA prior to

the MAP. If there is a deviation between aircraft altitude and

recommended altitude, state the difference. If above the

recommended altitude for 2 consecutive calls, recommend the pilot

increase his rate of descent to arrive at MDA prior to MAP.

2. There are 2 different techniques for the descent to MDA.

One is to maintain a gradual descent similar to the glideslope.

Another is to descend at a higher rate and arrive at the MDA

sooner. The goal of both is to arrive at the MDA with enough time

to visually acquire the runway environment prior to getting to the

MAP.

11. Report 200 feet prior to DH or MDA and arrival at MDA/DH.

12. For ASR approaches, direct the pilot to level off at MDA. Ensure the pilot levels off at and

maintains the MDA since, at this point, their primary focus will be visually locating the airfield.

Do not allow descent below the MDA. If the pilot descends below the MDA, direct an

immediate climb to the MDA ("climb to 680 feet").

13. MAP.

For ASR approaches, when the controller advises, "Over MAP," ask the IP if he has

the field in sight.

For PAR approaches, once you reach your DH or the controller advises "at DH"

(whichever occurs first), ask the IP if the field is in sight. After reaching DH, the

controller will continue to provide course and flight path information until the aircraft

passes over the landing threshold and you advise "Proceeding Visually" . This

information is strictly advisory in nature.

14. If the field is in sight and the aircraft is in a position to make a safe landing, descent below

the MDA/DH is authorized. If both conditions are not met, direct the IP to execute a missed

approach.
