Go-around below minimums
 
Hello! Typically, the list of reasons to initiate go-around includes such reasons as the runway is occupied or landing permission is not received. But I could not find any information about minimum altitude when go-around should be initiated if the runway is occupied or landing permission is not received. Can anyone help me with the answer to the question: to what altitude (DA/DDA or below) it is possible descend legally without landing permission or waiting for the runway to be to clear? Thank U!

Unless otherwise stated, crossing the threshold is the limit without clearance to land. Ref PANS ATM.

From what I've been told by a controller (FAA), as long as your wheels aren't on the ground, there's still separation.

I've seen ORD operate where the first plane is rotating while the second is in the flare. Closer than I'd like, for sure, but at busy airports here, it's not unheard of to still have the runway occupied as you descend below mins.

Depends upon the country? I've gone around just prior to the flare as the previous aircraft missed their second or third exit.

Looks like the 3-10-3 section of the U.S. controllers manual requires 2,500'(??). https://www.faa.gov/documentLibrary/media/Order/ATC.pdf

no permission to land before minimum, that is easy...GA. follow what is on the chart.

a GA or balked below minimums is an emergency procedure...therefore, there are no rules.

So if the minimums are 900 feet, you are visual with the runway, stable, etc, but don’t have a landing clearance, you are going to go around? Really? You might want to think that through.

Respectfully disagree.

Minimas can be quite high. A GA is never an emergency procedure.

Agreed with a caveat- terrain clearance is based on a go-around from the minima. For a go-around below minima you may need to be mindful of any special take-off procedure.

Some curious replies on here. Emergency procedure? No. If a go around to a professional pilot is anything other than a standard procedure then additional training is required.

You can go around from below the minima. Of course you can. What if you lose visual reference after the minima (eg large shower). Vis reduced to zero. “Oh well gotta land off this VOR approach??!”. What if you realise the gear is not locked, etc? The AIP specifically references going around from visual circling due to loss of visual reference. You’d never land st some airports if you required the clearance by the minima on a 2D approach. You can even go around after you have touched the runway in certain circumstances (not getting into aircraft specific stuff).

Perhaps the following criteria when deciding to GO AROUND:

1. Any SOPs, specific requirements / instructions in the AIP for the airport in question.

2. Good old fashioned AIRMANSHIP.

To answer the OP, in my company we would GA at alert height (200R on my type) if < CAT I and not in receipt of a landing clearance. In any other situation it’s up to the crew to decide...

Trossie 16th Sep 2019 09:54

An interesting one on the landing clearance bit: What about on an approach into CDG where you are cleared to land being number three on the approach?

I have done a few below minimums, the closest being as I was waiting for the wheels to touch and ATC said "XYZ Go around, er... can you make a go around from there?" By the time he had finished his transmission we were already climbing! He had spotted another aeroplane that had missed a taxiway turn and was about to infringe our runway. A formal 'thanks' was sent by our airline to the ATC unit.

Another landing that I did with a very late landing clearance was when, on a CAVOK day, a departing ahead was asked if he could expedite, said he could, was cleared to line up and take off, then 'dithered' (one of the 'legacy' airlines). We continued below 'minimums' as the go-around routing would have taken us straight into his climb-out with him being below our nose; using parkfell's 'point 2' we continued with a landing clearance as his wheels lifted off and we were near touching. We got a 'thanks' from ATC as we turned off the runway.

Quoted for thruth...

Flying on very short gravel strips in windy conditions teach you that quite fast. A go around is always an option.... all the way down to the ground, and sometimes a little longer (if you don't have thrustreversers and liftdumping devices)

Whether or not to land, that is in the end the decision of the pilot in command.... noone else.... even I as a ATCO can instruct a "go-around", if the pilot deems it safer to land.... he is in his right to do so (I've done my part).

A reminder of the question:

The answer is go-around by the time you cross the threshold if landing clearance is not recieved. Refs are PANS ATM 7.10.2, FAA Order JO 7110.65X 3.10.3, CAP 493 2.1.19, amongst others. I dare say most pilots have continued an approach past the threshold in anticipation that the overworked controller will imminently blurt out your landing clearance. Nonetheless you should understand that the separation minima for a runway does not depend on whether you have touched down, it depends on whether you have passed the threshold.

Wow. Competition is admittedly pretty stiff, but this has to be a contender for the title of "biggest load of bollocks ever written on PPRUNE".

Next time we hear somebody on frequency declaring an emergency because of a go around we will know who to look for ;-)

safelife 16th Sep 2019 11:58

oggers has it right. Runway threshold, or 50 ft above the runway, if you're looking for a vertical minimum.
Official solution in my company (operator of considerable size in Europe) after lengthy discussions.

Reading 3.10.3 and I didn't see any comment about requiring a go-around by the threshold. It mentions distance between the aircraft.

oggers 16th Sep 2019 12:13


oggers has it right.
Thankyou for reading and understanding the question.

safelife 16th Sep 2019 13:25

It’s actually quite reaonable... crossing the threshold at 50 ft is where the approach ends, and the landing begins.
You were cleared for approach, but not for landing, so go around at this point if you aren’t cleared any further.
